  1. Hello!


    I finally succeeded. I have an old 80GB SATA hard disk which I use to experiment with Mac OS. I had a Mac OS X 10.11 El Capitan installation complete with Office and other applications. Using Clover 3322 in iATKOS EC installer I managed to successfully boot it from within a virtual Mac in VMWare Workstation 10 (patched to support Mac OS). The SATA disk was connected to a SATA-USB adapter and then connected to the virtual Mac as a USB disk. I downloaded Sierra, but instead of creating a USB installation medium I stupidly tried to just upgrade by running the setup. The installation didn't succeed of course but while connecting and disconnecting the USB installer and the USB disk amd forcing several resets I finally screwed the partition and could not boot either in VMWare or natively in my PC. So I reinstalled El Capitan natively and then booted within VMWare. I successfully did all the upgrades up to version 10.11.6 and then downloaded Sierra again. This time I used Pandora's Box to create the USB installer. I booted the USB installer in VMWare and I installed 10.12 Sierra. For some reason it took a couple of hours, but it finally succeeded! It even made the sound and graphics work out of the box without having to install the VMWare Tools!


    Thank you for creating Pandora's Box! Pity I now have to reinstall all my applications...

  2. Hello!


    I'm not sure if my problem applies to this thread, but I wanted to ask you this:


    I have a perfectly working Mac OS X 10.11.0 El Capitan installation in my main computer. To avoid connecting and disconnecting the disk, I connect it with USB so I can easily remove it if I want to load Windows. The disk boots in UEFI mode in Clover and from there I load El Capitan. For some reason standard loading doesn't always succeed, but if I load it by ignoring caches it works OK.


    As you can imagine I have also loaded a lot of applications. I want to use that installation in VMWare Workstation (patched to support Mac OS X), so I created a new Virtual machine and the chosen guest OS is Mac OS X 10.9 (the higher on the list). I have the Mac hard disk connected to my host (Windows 10 Pro 64-bit) and upon starting the virtual machine I connect it to the guest. Since the main virtual hard disk is empty yet, the virtual machine tries to boot from the USB disk and starts clover. So far so good. The problem is when I choose to start El Capitan, no matter which option I choose (standard, verbose, safe mode, ignore caches), I see an error message "Internal Error" and the virtual machine hangs and closes. Does anyone knows what changes I have to do to the virtual machine settings and/or the VMX file to make it work? I would like to boot into the USB hard disk and then clone my El Capitan installation onto the main virtual hard disk, so I can use it and experiment with upgrades without fearing to destroy the original installation. Of course I would prefer to use my existing installation with all the installed applications. I don't want to start from the beginning with a new El Capitan installation!


    Thank you in advance.


    PS: Just to make sure, I restarted my PC and loaded El Capitan natively, it does work. I only have problem making it work in VMWare Workstation.


    EDIT: I recently downloaded iATKOS EC (El Capitan version) and I prepared a USB Flash drive for it. Before trying to install El Capitan from scratch, I decided to connect my El Capitan disk and boot it. iATKOS has a newer version of Clover, 3322, and it succeeded into booting my existing El Capitan installation in VMWare! I only had to install VMWare tools for the drivers and I'm good to go!

  3. These are entries in Clover's config.plist file? I will try that on the weekend. Thank you. Did you upgrade to 10.11.1 yet? Did it work? I wouldn't dare to try it and screw my installation...


    EDIT: I could not find the entries I have to change in config.plist file! I write the steps bellow in case I did something wrong...


    In Terminal I typed these commands:


    cd /

    cd EFI

    cd CLOVER

    sudo nano config.plist


    I then saw two settings for USB. The original settings are both true. I tried all other combinations, both false, one true the other false and vice versa, could not make the USB ports work. I plug a USB flash drive and it is ignored. Not even the LED switched on, no activity! Leaving the USB Flash drive connected and restart the computer made no difference! Of course I saved the changes and restarted the computer after each attempt.


    Any other ideas? Any USB kexts that support my Intel H61 chipset? Only if Apple wasn't that stubborn and allowed manufacturers to release drivers for Mac OS X! They fear that anybody would install Mac OS X on their computer! Is that hard to understand that this means profit for them, as more customers would buy Mac OS X?


    Thank you for your time.

  4. Well, today I used Clonezilla to clone the EFI partition from my USB Flash drive to the EFI partition of my disk. Now I can boot into Clover and this time choosing El Capitan works as expected and boots to Mac OS, so I don't need my USB Flash to boot any more. I also tried to copy all USB related kexts from my working Mountain Lion installation and installed them with Kext Installer, but this didn't make any difference. No USB device is detected, either connected at startup or connected after booting to El Capitan. Maybe the Mountain Lion kexts don't work in El Capitan or some boot parameter interferes with USB.


    Any help appreciated. Thanks.

  5. Don't push guys! Get in line, you'll have your chance to help! :P


    Anyway, I'll try cloning the EFI partition and see. As for USB I have a working Mountain Lion installation, I'll try to copy relevant kexts from S/L/E and install them with Kext Installer. I'll post back if it works, just in case anyone cares...


    No offence intended, but I see so many read my post an still not reply. Thank you anyway.

  6. Hello!


    I recently installed Mac OS X 10.11 El Capitan in a spare hard disk to test it. First I had not internet access, no sound and USB wasn't working. I managed to connect to the internet after downloading the official Mac OS X Realtek RTL8111F/8168 driver from www.realtek.com. For my audio card, Creative SoundBlaster Audigy Player, the download site of kxproject wasn't working, but fortunately I had saved the driver in the past. I tried to install it but installer would fail and not complete. I managed to install the kext manually using latest Kext Installer. I copied the kext file from S/L/E of an older Mac OS X 10.8.2 Mountain Lion installation and installed it with Kext Installer.


    However, I could not make USB work. No USB device is recognized, including my printer, my USB Flash drive or a USB external disk. In earlier Mac OS X version a USB disk would be used if connected at boot, but unfortunately this doesn't applies in my El Capitan installation. Could you please point me to the appropriate kext to download?


    Finally, I have problem installing Clover. My disk is formatted in GUID mode, and I have installed Clover in EFI partition. But when I try to boot to El Capitan from Clover, after a few seconds the computer restarts! I can only boot using the USB Flash drive with the El Capitan installer. The weird thing is that it has a slightly earlier version of Clover installed as well! How can I copy the boot settings from my USB Flash drive to my hard disk to make Clover work? I was thinking of using Clonezilla to clone the EFI partition, but this could make things worse. Please help!

  7. After many fruitless attempts, I concluded that this old notebook can only accept Mac OS X 10.4.8 Tiger from Jas. I cannot even update to 10.4.11. When I do, I get stuck at the desktop without icons loading forever. I managed to start the "universal" Snow Leopard installation from within Tiger and apparently complete it, but it won't boot (in verbose mode I see only two lines "loading mach_kernel" or similar and then it stucks). So I decided to abandon hope and keep using Windows. It's ridiculous since I can install Windows 7 and work without any issue (no aero, but who cares) while I cannot install anything newer than Tiger! Shame...


    Case closed.

  8. Hello!


    I have successfully installed and fully upgraded Mac OS X Yosemite to 10.10.2 in my setup. The only problem is that is doesn't normally complete the boot process, but I have to use the boot tags


    kernel -v -f




    kernel -v -x


    What can I send you to help me fix that? Some king of log? Please give details of how to do it as I am not very good at Mac OS.


    My setup:


    Custom-built PC with Asus P8H61 (Intel H61 chipset, 1156 socket), Intel Core-i3 3220 3.3GHz, 8GB DDR3-1600 RAM, nVidia Geforce GT 620.


    Thank you in advance. 

  9. Hello!


    I have a very old notebook based on Pentium M 1.8 GHz (no SSE3, maybe SSE2) with 1GB DDR RAM, Intel 855 graphics, 80GB hdd etc. I could successfully install Jas 10.4.8 Tiger on it, but by today's standards this is not very useful. Any other DVD (Kalyway or iAtkos Leopard or Snow Leopard) stucks before I even see the bootloader or it reboots. This means I can only use Darwin bootloader, not Chameleon or whatever fancy. Can I use the Jas 10.4.8 DVD to boot another DVD? How can I swap disks?


    Which are the minimum hardware specs for Snow Leopard (using a legacy kernel) ?


    Can I start 10.6 installation from Tiger? (I see a message to reboot). How can I do it from the Terminal?


    I'll give a try at Hazard 10.6.6 SSE2 SSE3 version (if I manage to boot it) an let you know.


    Thank you in advance.


    PS: An added difficulty to the project is that I don't want to erase the build-in IDE disk and I use a spare USB disk, I hope this doesn't affect my chances of success.

  10. The message you see is that USB could not identify, is not loaded and hence not working. You have to boot with the iAtkos DVD and reinstall. I would also format the partition, so to make a clean installation and not a repair. Before you proceed, click on the Customize button and make sure you include USB drivers. While you are at Disk Utility, make two partitions. One Mac OS Extended Journaled for Snow Leopard and one FAT32 for Windows. Later, when installing Windows, you'll see a message that you cannot install in FAT32. Format the partition to NTFS and proceed. At this point you should be able to boot to Windows but not Mac OS. There are some changes you can do to Windows Boot Loader to include a choice for Mac OS, but it is easier to just boot with the iAtkos DVD and install Chameleon bootloader to the Mac partition. Then you should be able to choose from Chameleon.

  11. Hello!


    I'm not sure if this has been asked before, but I couldn't put the correct key words to find it. Please give me the thread's link.


    I have taken an old HP Pavilion notebook, and a spare disk and decided to install Mac OS X 10.6 to see how compatibility goes and experiment. A common problem is that when I upgrade from 10.6.3 to 10.6.8 with the combo upgrade, my LAN and WLAN cards stop working. No matter what drivers (kexts) I tried, I couldn't make them work properly again and the only solution is to format and reinstall Mac IS X 10.6.3 from iAtkos DVD.


    The question: is there any way to backup the working drivers and make the combo upgrade? Then I could restore them and the LAN works as it should. Alternatively, can I select which components are being upgraded, so I make sure kexts aren't?


    Thank you in advance.


    PS: My specs: HP Pavilion zv6000 series, AMD Athlon 64 3200+ 2GHz (I use legacy_kernel to boot), ATI Radeon Xpress 200M chipset, ATI Mobility Radeon Xpress 200 128MB VGA (basic display, but I don't care), Audio ATI SB400 AC'97 (no audio yet), Reatlek RTL8139/810x LAN, Broadcom BCM4318 WLAN, TI PCIxx21 Flashmedia (not working), TI TSB43AB22 IEEE 1394.

  12. Hello! After posting the question, I came across this Apple support article: http://support.apple.com/en-us/HT203387 which describes how to fix Safari 5 not connecting to sites by disabling DNS prefetch. I immediately tried the code in Terminal. Of course it didn't work as my problem was driver related, so I found a USB WLAN dongle and plugged it in to use it. MacOS couldn't install a driver automatically, so I used the bundled CD-ROM. However for some reason my Yosemite installation is very sensitive. Any time I change something such as installing or uninstalling a driver, it simply won't boot again and I have to use the installation USB Flash drive to repair it. So I did it once more and after repair it still couldn't see the USB WLAN dongle (driver wasn't installed just the Railink wireless utility), but it could finally connect to the internet using the onboard Reatek RTL8111F Gigabit ethernet card! Of course I don't care what happened and why, I at last can enjoy Yosemite without making a clean installation and having to reinstall tons of programs!


    Now I have a different problem: I can only boot properly to Yosemite using the installation USB Flash drive! I tried to install latest Clover in the first partition, it boots to Yosemite, but the screen is blank (out of range?) How can I fix that? Please point me to the relevant thread. Should I try Chameleon instead?


    Thank you!


  13. Hello!

    I have recently downloaded MacOX X 10.10 Yosemite. In my current PC I have a disk with two partitions, and the first

    contains a working Mountain Lion installation. I didn't want to upgrade to Yosemite, in case something goes wrong.

    So I used Super Duper to clone the Mountain Lion installation to the second partition, then upgraded that to

    Yosemite. So I can know test Yosemite but also keep a working Mountain Lion partition. In Yosemite everything seems

    to work OK except network. The card connects to the router (status connected) but I cannot browse pages in Safari,

    I cannot use Apple Upgrade etc. Changing to manual IP and DNS settings didn't change anything. The troubleshooter

    recommends restarting the router, but this didn't help either. The weird thing is that I can ping to the router, the

     other computers and my ISP DNS servers! So what is going on? Please give full details as I am a novice to MacOS.

    Thank you in advace

  14. Hello!


    Sorry if this has been already asked, but I didn't find something similar with a quick search...


    Little background first: I had an old 120GB hard disk which I had formatted as MBR and had two MacOS partitions. In the first I had Mountain Lion 10.8.4 installed, and at the second Leopard 10.5.2, as a backup in case something goes wrong with the Mountain Lion , to be able to boot into Leopard and fix it. Yesterday I decided to download and try Yosemite 10.10.1 (latest). I used SuperDuper to clone Mountain Lion from the first partition to the second (I didn't wanted to do a clean installation and have to reinstall everything). Then I downloaded Yosemite from Apple Store and tried to upgrade the second partition. I got the error message that I should reformat the disk to GPT! No way I was going to lose all my data and didn't had a spare disk to install there. So I used a utility to create a bootable USB Flash with the Yosemite installer and then patched the appropriate files to allow installation/upgrade to MBR disks. I then had to boot the USB Flash with GraphicsEnabler=Yes and -v options since after detecting my card (nVidia Geforce GT 620) I lost display (out of sync). So far so good, I upgraded the second Mountain Lion installation to Yosemite 10.10.1


    My problem: I installed latest Clover, but I got a Boot0=OK, Boot1=error message, so I installed latest Chameleon with GUI. From Chameleon I can only boot to Mountain Lion (first partition), when trying to boot to Yosemite (second partition) I get an error message such as "kernel no found". I can only boot to Yosemite using the USB Flash installer. I tried to copy a kernel file to System/Library/Kernels and some other files, but I screwed Yosemite, so I now try the upgrade/repair from the USB, otherwise I will have to clone Mountain Lion with SuperDuper again and redo the upgrade. Any ideas? Any setting/configuration in Chameleon I am missing?


    Another minor problem was that my network card (Realtek RTL8111F Gigabit LAN, onboard) was supposedly connected to the router, but couldn't connect to the Internet. But this should fix as long as I install latest OEM drivers from www.realtek.com


    Thank you in advance

  15. I had Acer AspireOne 150 with similar specs. I couldn't install Snow Leopard directly, so I created a smaller partition to temporarily install Leopard so I could use the terminal to install Snow Leopard and make it work. The only version that works right away without any tweaking is Kalyway 10.5.2. I then downloaded an Atom kernel to replace mach_kernel, DSDTSE to compile my won DSDT file and some other kexts I don't remember right now. I followed this guide:




    I created three paritions since I wanted dual boot with Windows 7. After successful installation of Snow Leopard I deleted the Leopard partition and expanded the Snow Leopard partition to take all free space. After installation, with the given kexts, webcamera worked fine, graphics worked at 800x600, not 1024x600, but sure this can be fixed with appropriate Intel GMA 950 kext. Ethernet worked only when booting with the cable connected, otherwise it couldn't detect the cable and had no internet! This was fixed by installing the official Realtek driver from Realtek's site. Wireless never worked, no matter what I did (maybe I needed a driver for the key combination to enable WiFi as well). I had installed MacDrive to Windows 7 so I had full access to the Mac partition. I then backuped the atom kernel and restored it after each combo upgrade. This trick worked and could do all upgrades up to 10.6.7. It didn't work for 10.6.8 though, so I eventually deleted the Mac partition and expanded Windows to take all disk...


    I hope that helps...

  16. I think compatibility makes it popular. Snow Leopard can be installed in all PCs at least Pentium 4 3GHz (Prescott) while Lion and Mount Lion require at least Core 2 Duo system. Also Rosetta is very important for old applications. I recently installed MacOS 10.5 Leopard on a real PowerPC Mac. The owner is a graphic artist that is used to certain versions of Photoshop and Illustrator. All of them work without any problem up to Snow Leopard. In Lion and Mountain Lion he would need to buy newer versions that apart from the associated cost, he would have hard time to master. When you use a computer for work you don't want to lose any time for training, you want to be ready for work at once. So I prefer Snow Leopard over newer versions. Beside some new features, I didn't see anything else that you cannot live without. The biggest problem is upgrading to 10.6.8 since if not done correctly, the system will not boot. I had Snow Leopard installed on an Acer AspireOne 150 netbook and could do all upgrades up to 10.6.7 without any problem. After each combo upgrade I simply replaced the mach_kernel file with the custom Atom kernel one and it worked. But when I did the mistake to upgrade to 10.6.8 the system never booted again. I didn't have the courage to reinstall MacOS and all applications from scratch, so I just deleted the Mac partition and expanded Windows to take all disk.

  17. The safest approach is to connect a separate hard disk for the Mac. Make sure you disconnect your Windows disk and have only the Mac disk connected during installation. When both disk are oresent, set boot priority in BIOS so the Windows disk is first. This will boot automatically into BCD where you select Windows 7 or XP. All you need to do it edit the Windows bootloader (use EasyBCD) and add an entry for MacOS. Unfortunatelly the default Mac settings in EasyBCD don't work, but once you create the boor entry you can modify it in command pormpt with BCDEDIT to point to file \chain0. This file is included in many Mac bootloaders such as Chameleon and is usually found in the root of the Mac disk. Another usefull utility is MacDrive for Windows. It makes Mac partitions appear in Windows Explorer as they were NTFS partitions and you can read and write seamlessly.

  18. Probably has to do with the hard disk boot priority. When all disks are connected, Windows cannot boot if the 1TB disk is set as second in order. It has to be set as first. In that case you have to set 1TB first to boot into Windows and the SSD first to boot into MacOS. Otherwise, you can create a boot entry in Windows bootloader to load MacOS. It has to point to the file C:\chain0 which you can copy from Mac partition to the root of 1TB.

  19. Γιαττί το πιστεύεις αυτό; Πραγματικά μου αρέσει πολλή η Αππλε και θα αγοράσω ενα Μακ, αλλά εδώ και 4 χρόνια είμαι ολοκληροτικά χρήστης Λινουξ.

    Δοκίμασα: Ubuntu, Fedora, Mint, Arch Linux και πολλά άλλα! Το Arch Linux είναι μια διανομή λινουξ που οταν την εγκαταστήσεις μπένεις σε περιβάλλον ΜΣ-ΝΤΟΣ και πρέπει να κάνεις εγκατάσταση απο πληκτρολόγιο σε γραφικό περιβάλλον ήχο και άλλα. Αλλά οι άλλες διανομές είναι πραγματικά εύκολες αρκεί να ασχοληθείς και να ΞΕΣΥΝΙΘΉΣΕΙΣ τα παράθυρα η το Μακ.

    Και όταν το Ubuntu ανακοίνωσε το Synaptic που μετά πείρε την ονομασία Ubuntu Software Center δηλαδή μια πιο φιλική έκδοση του Synaptic το Μακ και τα Παράθυρα έπρεπε να κατεβάσεις το πρόγραμμα και να το εγκαταστήσεις (περισσότερες πιθανότητες να κολλήσεις ιο). Και στο Μακ σου μπορείς να εγκαταστήσεις προγράμματα απο το τερματικο!.

    Ακριβώς εδώ είναι η δυσκολία. Καλώς ή κακώς οι περισσότεροι ξέρουμε από Windows γιατί σχεδόν όλοι οι υπολογιστές τα έχουν προεγκατεστημένα. Οπότε το να ξεχάσουμε ό,τι ξέρουμε και να μάθουμε κάτι διαφορετικό έχει έναν βαθμό δυσκολίας. Στα Windows ό,τι θέλεις γίνεται σε γραφικό περιβάλλον, ενώ αρκετά πράγματα στο Linux αλλά και στο Mac χρειάζονται το τερματικό και δεν είναι ό,τι καλύτερο για τον μέσο χρήστη που θέλει απλά να κάνει την δουλειά του. Ναι το Synaptic έχει απλοποιήσει την εγκατάσταση προγραμμάτων, αλλά όποιος θέλει να βάλει κάτι με τον παραδοσιακό τρόπο (βρίσκω αυτό που μ' αρέσει στο internet, το κατεβάζω και το εγκαθιστώ), σε αρκετές περιπτώσεις παιδεύεται πολύ περισσότερο στο Linux απ' ότι στα Windows. Αυτό ξενερώνει απίστευτα αρκετούς χρήστες και τους κάνει να σκέφτονται μήπως δεν ήταν και τόσο καλή ιδέα τελικά να εγκαταστήσουν Linux. Ειδικά αν τύχει κάποιο hardware που έχουν και δεν δουλέψει στα Linux, εκεί τελείωσε, πάνε για φορμάτ.

  20. Well I once had dual boot Windows 7 and MacOS X 10.6 Snow Leopard vanilla (official, not distro). In order to make the MacOS X 10.6 install successfully and boot, I needed some specific kexts and a temporary MacOS X 10.5 Leopard installation to use the terminal. I created three paritions, one small for MacOS X 10.5 Leopard, one larger for MacOS X 10.6 Snow Leopard and the rest (larger) of the disk was reserved for Windows (initially formatted as FAT32) as it would be my primary OS. In your case you could include one more for Linux and a smaller for Linux swap, total 5 partitions. The MacOS X distro that works in almost every hardware, is Kalyway 10.5.2, so I started booting from an external DVD-RW and booted into Kalyway DVD. I used Disk Utility to format the disk as GUID and create the three partitions. First was Windows, so I could later delete the other two and expand it, should I didn't want MacOS anymore. It was formatted as FAT32, so Windows installer would later detect and use it. Second was MacOS Extended Journaled intended for Snow Leopard. The temporary MacOS Extended Journaled partition for Leopard was placed at the end, so later I could easily delete it and expand the Snow Leopard partition to fit all space. I then proceeded to install Kalyway 10.5.2 in the last partition. I didn't need to configure anything, it worked automatically as I was installing Linux instead of MacOS! Well done Kalyway, pity it is too difficult to upgrade it and you stay at 10.5.2  :(

    Then (from Leopard) I formatted a USB flash drive as MacOS Extended Journaled and made it bootable (installed Chameleon), just in case. I used a Snow Leopard DMG to install Snow Leopard on the second partition. As expected the boot sector was changed, so I used the flash drive to boot into Leopard again. I then used DSDTSE to create a custom DSDT file that matched exactly my hardware and BIOS version, and Atom kernel and some other kexts (downloaded from http://www.osx86.net/). I followed a guide to install chameleon, the custom DSDT file and the kexts as needed using the terminal. After all steps were completed successfully, I could boot without the flash drive and use chameleon to go into Snow Leopard. When I was 100% sure I could use Snow Leopard without any problem, I deleted the Leopard partition and expanded the Snow Leopard partition to fit all space. I proceeded installing applications. Wireless network didn't work. Wired worked only if booting with the cable connected. If you removed the cable and connected it again, it wouldn't detect it. This issue was solved by installing official Realtek drivers from their site.


    Then I installed Windows 7 in the first partition (after formatting it to NTFS from Windows Setup). At this point I could boot into Windows but not MacOS. One solution was to boot into Snow Leopard using the flash drive and then install Chameleon again. This way I would boot into MacOS and select Windows from Chameleon as needed. But I wanted Windows to be my primary OS, so I edited Windows bootloader to inculde a MacOS option instead. So I booted into Windows or selected MacOS from Windows bootloader as needed. I installed Macdrive so I could access the Mac partition from Windows 7 and I made a backup of the Atom kernel. Every time I did a combo upgrade in MacOS, I booted into Windows, restored the Atom kernel at the root of the Mac partition and I could boot in MacOS again wthout any issue having the latest version.


    WARNING: Restoring the Atom kernel worked up to version 10.6.7. It didn't work after combo upgrade to 10.6.8 and I could fix my Snow Leopard installation! I gave up, deleted it and expended Windows partition to cover the whole disk. I didn't like to go through all this trouble again to reinstall Snow Leopard and all my applications. So be extra careful. Download and install manually the 10.6.7 combo upgrade. DON'T upgrade to 10.6.8 or you won't be able to boot again!


    I hope that helps. :)


    PS: In your case, since you don't want to reinstall Windows, I would try installing Snow Leopard in MBR mode. It is possible, but I don't know how, sorry... Just a thought, why don't you create a backup of the Windows partition (with Acronis or Clonezilla) and then format the disk in GUID mode and proceed as above? You should later be able to restore the Windows partition instead of reinstall Windows and use the DVD to make it boot into Windows (repair Windows). It could work and save you the trouble to reinstall everything in Windows :)

  21. To convert the disk from MBR to GPT, you can go in Windows, right-click the Computer icon, select Manage. You see Computer Manager. Click on Disk Manager. Select the disk and right click to see the options. There is a "Convert to GPT", but I'm not sure if it will allow you to do it and if that will affect your Linux installation. Do it at your own risk... I would try to reinstall MacOS using different settings related to SATA.

  22. As already said, you can do the same thing in all OSes, but not the same easy straightforward way. In my opinion, Windows has much more software to choose from, so why limit oneself with a few software for MacOS or Linux?  Moreover, most MacOS or Linux applications have a PC port, so just use the Windows version if you want something specific. Any piece of hardware has a driver for at least Windows XP, but in MacOS or Linux you may have to rely on third-party drivers, or not work at all. If it does work it may not have all the features you paid for, only basic functionality and certaintly I don't like that, even if I hardly use all the features, I grade compatibility too much to compromise, this reason alone hinders me making MacOS or Linux my primary OS. I may dual boot for the experience, but my main everyday OS is always Windows, unless something else proves competitive to my eyes. That's why Apple should allow Mac clones (Hackintoses) as IBM allowed PC clones in the past. All major companies would provide official 100% all-feature working drivers for their devices and MacOS port of their application. Then MacOS X could be very competitive with Windows and gain a comparable market share. Yes, the price of MacOS would rise a lot, but it would still be cheaper to buy it and use a PC instead of a real Mac. For Linux to do the same thing, the developers must concentrate on providing good all-feature drivers for most well known hardware. If there would be a way to recompile/emulate Windows drivers would be a great benefit. Is that hard to dissasemple the code of the drivers and create a MacOS or Linux compatibile code? Yes, I know copyrights make that difficult... But if the Linux had a greater user-base, the OEMs would provide their own official drivers. Now they simply don't bother. Yes, having a greater user base would attract malware programmers, but you cannot have it all. That's why Antivirus software is used for. It would also be a chance to see if MacOS or Linux are really as secure as they claim to be. In real terrms, not in theory. I believe that there is no 100% foolproof secure OS. In any OS, having an up-to-date antivirus AND be careful what you click, you shouldn't have any problem. In MacOS and Linux, the user simply enters the password every time it is asked, and that's it. The malware can do whatever is programmed to do. And it certainly doesn't need any more rights to do damage.


    Until MacOS and Linux have the compatibility of Windows, sorry I vote for and recommend Windows to everyone. I don't trash other OSes, I would install them to a friend that wants to experiment, but not as a primary OS, and of course he would have some good knowledge of PCs. I wouldn't recommend it to a newbie, since when he would have any problems, I would have to help him and unfortunatelly this would happen annoyingly frequently (sorry if the last expression is not correct, but you get the point). An advanced user makes fewer questions which can be solved by phone. A newbie would require to go his place or connect with TeamViewer, and of course, I wouldn't charge a friend... Doing too many "favors" and wasting too much time for free is not what I want, I don't know about you... ;) Of course this excludes helping others through a forum. But you do it in your own time because you like it, not forced.


    And a last thing, I am a Windows expert, so I can easily help my newbie friend in Windows. In MacOS or Linux I would have to search for the solution in Google wasting too much time. Some other poster said to be at the same level in all three OSes before judging. Yet another reason for me to vote for Windows. To get in MacOS at the same level as Windows (well, as an advanced user, not as a technician that would require much more time) would take roughly the same time if not a little more. This is because I'm familiar with Windows and I try things the Windows way. If they are done differently, I have to spend some time to figure out how to do it. In Linux this is much worse since they are not as easy and straightforward as MacOS. (I found many similarites between newest Ubuntu and MacOS Mountain Lion by the way). This means Windows has a learning curve A, MacOS has a learning curve A+B and Linux is even steeper with A+B+C (in terms of time). (That's what I meant by "user friendly" in previous posts. Learning curve is also important). I prefer it the easy way, so I choose Windows hands down when it comes to learn using a computer. By using I don't mean only connecting to Facebook and reading your e-mail, sometimes typing a document. I mean knowing how to configure stuff as well and add/remove programs. Being an adnanced user and progress, not staying a novice forever!


    One more and the most important reason for a gamer: Games. Yes, Steam is on Ubuntu now, but most others are not. Playing a Windows game using Wine doesn't count. I speak of native games.


    For all the above reasons, I vote Windows. Other OSes are for experimentation, unless you are an graphics artist or similar using a Mac. But here I refer to the average user, not some specific professionals. For the average user, it is Windows, I insist. Artist could use the Windows version of their applications, so there is no excuse.
