Hi,

 

Well it is the time of the year that I have come to dread... the release of a new OS X and the endless number of hours trying to get the damned thing working!.  So in preparation for the final release this week (hopefully) I am asking for some pre-installation-attempts advice!

 

My skill/knowledge level will probably get me through the installation process (creating a bootable USB stick etc) using the guides on here; but I usually fall over when it comes to getting sound, USB etc to work.

 

My current 10.9 Mavericks system works flawlessly 99.9% of the time and most things work OTB... but the bits that I have fiddled around with in the past with are:

  • DSDT:  I know nothing about editing these files.  My current DSDT has been fiddled with by a member of this forum in the past and I believe he added/changed some of the code to enable my graphics card (Geforce 9800GTX) to work.  I may be remembering wrong, but someone at some point, again from these forums, may have attempted to get my audio (ALC898) to work, however...
  • Audio:  If someone has attempted to fix my audio using DSDT, then it never worked. To get my audio working I have been using the beast that cannot be mentioned.  The latest version claims to place a patched AppleHDA.kext in /S/L/E aswell as doing something to the DSDT refering to layout-id and adding some parameters to org.chameleon.plist.
  • Networking:  The UD5H has two onboard ethernet ports; one Intel and one Atheros.  The Intel one works OTB I believe whereas the Atheros requires a kext.  I am going to assume that either the current kext for the Atheros will still work for Yosemite, or the guys that created it will update it for Yosemite.
As I see it, audio is going to be my biggest gripe.  While beast has always worked, I don't like the idea of messing with system files that need to be re-installed everytime there is a 10.10.x update.  Ideally I would love for audio to work without the need for messing with AppleHDA.kext.  Is this possible?  I have never understood what AppleHDA, HDAEnabler etc all do and how they function.  If anyone could explain in lamens terms?

 

Can anyone say how iCloud services function?  Does iMessages work? (At the moment I'm unable to use iMessages;  I have the contact support with customer code dialogue when I try and sign in.  I understand I can fix this but have been putting it off till I get Yosemite installed.  Does the AppStore work ok? 

 

Finally, I have been using Chameleon bootloader ever since I started with the Hackintosh and now I hear about Clover.  Which of these bootloaders should I be using?  I predominantly hear of Clover, so assume this is the one I should be using?

 

I have included an zip file with my current DSDT, smbios and org.chameleon.plist for those who think looking at them might help.

 

Thanks for reading.  Any advice is welcomed.  Thank you.

OK. @stuppy_,

 

I assume that you have the Z77x-UD5H which is the same one I have. I currently run Yosemite beta 6 which I suspect is the final. 

 

1. I used this excellent installer by Chris:

 

http://www.insanelymac.com/forum/topic/301138-new-usb-installer-os-x-yosemite-beta-1234-chameleon-enoch-r2403/

2. I don't like Clover, too complicated because you have to flash the BIOS

 

3. The Sound I use the kext from here for ALC898: by Mirone

http://www.insanelymac.com/forum/topic/298663-applehda-for-yosemite-dps/

 

4. The internet i inject the AppleIntel1000e.kext by hnak

 

For your convenient use this file, included

 

Good luck


BTW Apple store and iTunes store work. iMessage and iCloud FaceTime not working yet. NVRAM mod for Mavericks no longer works. Some experts may come around and fix this when the final version is out.

ok, with your knowledge and lack of interaction with boot loaders in general I would recommend setting up your dual bios and running ozmosis 894m.  it will make running your hack much easier and stable in the future. if you post your DSDT and config.plist from your boot loader I can configure a copy of the Ozmosis boot loader so that all you have to do is flash it and walk away. OS X will boot directly from bios just like linux or windows and will not need any any alterations from that point on and best of all there will be no (this os update broke my boot loader).

 

if you want to take me up on the offer what I need are:

a copy of your boot loader plist (so that I know what type of machine you are emulating and the serial etc)

your eth0 MAC address so I can set the ROM setting in bios (fixes iMessage issues)

your DSDT.aml file and the type of sound card you are using (so that I can integrate the patches into the DSDT tables)

 

what you can expect booting from ozmosis, extremely fast boot times, the computer is no longer booting a boot loader then an OS.

a very stable configuration that runs without needing FakeSMC, and other kexts (they are built into the BIOS)

 

Hope this helps.

HBP

PS I am not responsible for bad flashing, and make this above statement from the information provided in the first post.

 

@Cyberbuddhah,

     to fix the iMessages issue, set the ROM to your eth0 MAC address in base64, then call apple and have them unlock your account with the code provided, it should never pop unauthenticated again.

Your idea sounds interesting. I have a few questions before I would consider this.

 

Firstly I believe my mainboard has dual bios. If for whatever reason the flashing fails, my second bios chip would be fine? And then I can reflash the bios that failed and try again? Or is it a case of once a flash goes wrong, that bios chip is lost forever? I have flashed my bios before , though only updating using gigabytes own flash files.

 

Also once the bios is flashed with ozmosis, would I lose access to the bios setup screens themselves (ie where you can set cpu speeds, ram timings and disable onboard devices etc).

 

Further, your bios flash using ozmosis; would it mean i would no longer need to mess with audio drivers and network drivers? Everything on my computer would work as if it were a genuine Mac once installed?

 

Thanks. :)

page 23 of your owners manual shows the procedure to activate the second bios incase of bad flash, it is as simple as flip a switch, next to gsata3.  as for reflashing after a bad flash, load from good get into the @bios software, or the bios flash utility  and flip the switch back, it will then flash the one that was misflashed and leave you with one that has been untouched.

 

once installed the only thing you lose access to is UEFI network login (which 99% of folks don't use) this is a mode for bios updaters to log the computer into a network without any os at all to install drivers for the UEFI bios.

 

you still can use F12 to get a boot menu, or delete to get into bios, it doesn't delete bios, it adds functionality to bios.

if you need a patch for sound, you will still need to patch sound, and you will still need to install any updated network drivers if your nic is not already on apples 'list'.

 

the only difference with using osmosis from another boot loader is that apple can't bork it with the next patch. once installed it is stable and the only things you need to worry about is where is sound and audio...

 

and it boots everything, even if you frag your HDD. toss a new drive in and the installer key direct from apple (they have instructions on how to make them without all the headaches for REAL MACS) and it will boot and install just like it thought it was a mac.

Hi HBP

Thanks again for the advice and I hope you don't think I am trying to find disadvantages and reasons why your method is the wrong method, however there are a few things that still confuse me that I would be really greatful if you could answer :)

You say flashing the bios using ozmosis means no need for a chameleon/clover boot loader and that there is no chance of these boot loaders being trashed when Apple updates are applied. In the years that I have used said bootloaders, not once have they been affected when running apples updates. The only thing that I have had to fix when installing updates is the audio; and from what you're saying I would still need to fix these things when I run updates. Unless I am misunderstanding I am in no better position using your method?

Again, please don't take what I am saying and asking as ways of ripping your ideas apart. I am genuinely thankful for your educative comments. Just need to understand more about what you're suggesting and the pros and cons. With chameleon, I at least have a working understanding of how it works and how to fix some issues with it, without having to keep asking on here.

Thanks :)

EDIT:

 

 

Actually HBP,

Having just done some looking into this a bit more through Google, it seems far way out my comfort zone so I will not be messing with the BIOS.

 

Thanks again for your advice and help!  Thank for the time being I will stick with Chameleon :)

no problem, to answer your other question in case others reading would like to know, the difference in boot speed and knowing that my bootloader will be compatible with the next release of osx is reason enough for me on why I updated my bios.

 

Before ozmosis, from power on to password was 1 minute 8 seconds with clover and 2 second delay at the partition selection screen on a fusion drive.

After ozmosis, from power on to password is 22 seconds, (caveat there is not a boot menu every boot, you have to hit home/alt to get one) so add 2 seconds to it for the boot menu, a total of 24 seconds.

This was more then double the speed of clover, and all my stuff, including power management, CPU throttling, and the like works.

Hey

 

Just to update anyone who read this topic. I managed to install Yosemite relatively easily, once I had got past a couple of problems using Chameleon and where the kernel is now stored in 10.10.

 

Once I got it installed though it was a piece of cake. Been using it a couple of days now and seems to be stable. Speed stepping works, audio works, even sleep seems to work, not that I use it.

 

My only issue now is that iMessages won't work. I believe it is something to do with nvram and chameleon. I can live without it but hopefully a fix will come along in the coming weeks :)
