For some reason i can run ML on VMware with this machine but I cant install for the life of me.


I followed this Tut: Click here

For some reason I am getting stuck at Still waiting for device. (picture attached)



My Rig:

CPU: Intel® Core™ i7-3630QM Processor

Graphics: NVIDIA® GeForce® GTX 670M with Optimus™ Technology 3GB GDDR5

Memory: 12GB DDR3 1600MHz memory

HDD: 1.0TB: 500GB (7200rpm, Serial ATA) + 500GB (7200rpm, Serial ATA)

Optical: DVD-SuperMulti drive (+/-R double layer)

Wifi: Intel® Wi-Fi® Wireless networking (802.11b/g/n + WiDi Capable)

Bluetooth: Bluetooth® V4.0

USB:4-USB (3.0) ports

Any one help me PLEASE!




So I was able to Boot and install ML using a boot CD which was from OSX86.net But I cant boot into the OS I have tried the following boot flags;

-v -F -x maxmem=4084 busratio=18 npci=0x3000 PCIRootUID=0 and 1

This is what I get



Instead of getting Still waiting.... Error I get a Kernel Panic. But I myself cant figure this out.

Any help would be awesome.

Those screens are hard to read.

Well, copy the following kexts to the Extra folder of the USB installer you have created.


Boot with -f -v


Okay I tried this copied them both to the Extra Folder on my USB installer.

Booted with -f -v

and got this


Hopfully this image isnt as blurry, I get the same reaction from my system, I am going to try booting with PCIRootUID=0 npci=0x3000 -x -v -f see if that changes any other is appreciated.

Well, this shouldn't be happening. You need to know which AHCI SATA controller your system uses, Boot Windows, if you still have it, and get this info from the Control Panel/Device Manager or using Everest.exe, then post it here.


Best regards!

Well, your chipset is intel: Intel® 7 Series Chipset Family SATA AHCI Controller.


That means high compatibility with OSX. This issue should not be happening, and you should be getting your installer to work without any issues and modifications. But laptops are always harder to sort out. You'll have to start over. Use the same guide: i used it a lot of times with 100% of success. Take it slow: a single misstep and you'll have issues. Please report back here when you're done.


Best regards!

The HD4000 and the intel Centrino wireless are not supported , you can buy a wireless card that will work for around 20 $ but it involves opening up the laptop and replacing the chip , not hard at all but yea. for the resolution fix just find the chameleon.plst and add the graphics mode tag and the desired resolution ex 1600x900x32 then it will display correctly no gpu acceleration tho. If you download ##### it contains the drivers for the trackpad and sound and keyboard.

      Breaks out my shield and gets ready for the flac
      I deleted a line out of the root which was associated with my Bluetooth device
      sadly like all things I now realize I shouldn't have done that tried to find the deleted line and well, was not able to.
      I now have no Bluetooth devices even when I plug in different usb Bluetooth dongles.
      so my question to those with more  wisdom is :- is it possible to extract the missing line from the Mojave installer and re install it
      or is it a re install only?
      I am not too concerned if it is a re install, we all learn and even an old git like me still learns. I did try x code Bluetooth to re install that way
      but for some reason it did not work.
      remember go easy you will be an old git one day
      thanks and waits for the stick

      I can't connect the phone. I tried some ways but no changes.
      config.plist and information screenshoot attached.
      I am new so please forgive for information mistakes.
      I just changed device information in config.plit (smbios)
      It should be matched my build, iMac 14,2 just fine right now.

      Ciao a tutti,
      sono felicemente riuscito a installare Lion sul mio Optiplex 330.
      Funziona tutto tranne la scheda audio interna ma non importa perché vorrei installare una USB esterna: una Yamaha AG03.
      Dalle istruzioni questa dovrebbe essere installata su Lion senza driver e riconosciuta subito (http://www.yamahaproaudio.com/global/en/products/mixers/ag/manual/mac/index_en.jsp).
      Su un altro hackintosh sempre con Lion viene riconoscita perfettamente.
      Il sistema la vede, nel System Report, correttamente collegata all'USB ma da Audio Midi Setup mi dice "NO DEVICES FOUND".
      Temo che mi manchi qualche parte software per far riconoscere la scheda esterna.
      Ho installato i VoodooHDA ma mi hanno mandato in crash il sistema quindi li ho rimossi.
      Avete consigli?
      Grazie mille
      Retroman Newbie

      Recently, I have been having weird issues installing Sierra to my newly created partition. It always ended up with a NASTY error message saying that it could not unmount the volume for repair (what repair, anyway?). At the first, I thought the volume was dirty, so I booted to my working El Capitan again and had formatted the partition again. It still failed. Then, I thought it was the fact that I was using the installer in El Capitan to install it to the new partition. So, I created an installation USB. The problem surprisingly appeared!
      The problem:
      The problem I believe was due to the createinstallmedia tool. If the USB is in fact created with that tool, the installer divides the installation process into two. First, it copies the installation files to the HDD partition (that part creates problem), and then it reboots from that partition to install the files and eventually create the Recovery partition. The problem is that it for some reasons tries to unmount the partition it has booted from, which is obviously not possible; hence, it fails. The root problem probably has much to do with the partitions structure. In my case, I used MiniTools Partition Manager to migrate my Windows installation from my HDD to the new SSD drive. It could have been due to that, although MSR partition is also known to cause problems in some situations. The partition structure was as follow:
      ESP = EFI Partition MSR = Microsoft Reserved (culprit, too?) Win10 = Windows drive Sierra = New partition created for Sierra Macintosh HD = El Capitan drive (already installed and working) RecoveryHD = El Capitan recovery drive.  
      The solution:
      Use the "Restore BaseSystem.dmg" method to create the installation USB.
      Follow these steps:
      I assume that you have downloaded the installation from Mac App Store. If so, then right click on the file, click "Show Contents Packages". Click on "SharedSupport". You should see InstallESD.dmg. Double click on that file to mount it. Open the OS X Install ESD partition. Make sure that hidden files visible (there are many ways, use Google). Right click on BaseSystem.dmg and click open to mount it. Open Disk Utility. Plug in your USB drive. Click "Partition" and create too partitions. One with 200MB and the other one with whatever size you want. The 200MB partition format should be MS-DOS (FAT) and give it CLOVER as name. The second one's format should be OS X Extended (journaled) and give it USB as name. And click "Apply" to format the USB. Of course, everything on that drive will be destroyed. It's needless to say that you should backup its contents first. While still inside Disk Utility app, click the second partition (it's should be named USB). On the status bar, click on "Edit" and choose "Restore". You should see "Restore from: OS X Install ESD" click on "OS X Install ESD" and choose "OS X Base System" from the dropdown menu. Now click "Restore". You might need your password to complete this task. If so, type it in and click ok then wait. Upon finition, smartly unmount OS X Base System disk under "Disk Images" in Disk Utility. Open the USB drive (the name "USB" will become "OS X Base System", that's why you need to smartly unmount the other one using Disk Utility to avoid confusion.) Inside the USB drive, go to "System" then "Installation" remove the file named "Packages". That's actually an allias (or a shortcut if you want). Go to OS X Install ESD drive. Copy "Packages" folder from there and paste it in your USB/System/Installation. The same way, copy the other files from OS X Install ESD drive to the root of your USB (the root, not inside a folder on the USB drive). You need to typically copy the following files: AppleDiagnostics.chunklist, AppleDiagnostics.dmg, BaseSystem.chunklist, BaseSystem.dmg Install Clover to the first partition of your USB drive named CLOVER (unless named otherwise). Reboot from the USB drive and everything should go smooth and without this error. This should also work for Chameleon bootloader. You might of course not need to create two partitions in this case.
      You should probably not directly upgrade from El Capitan to avoid this problem. If it happens while you were trying to do an upgrade, you might need to do these steps inside a virtual machine or a working hackintosh.
