quicklan posted a question in Hackintosh YosemiteHi all, So I got yosemite 10.10.1 working nicely on Virtual box on my HP DV7 laptop. Only thing is that the sound was crackling... I tried installing the "All in one Audio solution" driver and a couple other drivers but now I have no Audio device...doh! Pretty sure I messed it up. I would like to know if there is a solution for this problem or some driver to install, have searched around but nothing really conclusive, if not, does anyone know how to get back to the initial driver without re-installing the whole darn thing.... Many thanks. In the mean time here are a couple of errors I did manage to fix during the install on VB for anyone stuck on these, this worked for me best one is at the bottom: 2 mins remaining fix You can also do in VMware Workstation .. 1. Close the VMachine when stuck on 2 minutes left (Power off) 2. Start it again, select newly created hd(0,2) <yourpartitionname> and type options: Step1 :- -s -v -x 3. You will get to bash, run two given commands to mount root device. or just see above 4 lines you will find two category ... Step2 :- /sbin/fsck -fy and when it finishes: Step3 :- /sbin/mount -uw / 4. Now move to the directory: Step4 :- cd /.OSInstallSandboxPath/Scripts/ and show its files: Step5 :- ls 5. In the result you need to find the .xxxxxx from Hackintosh.Zone.Post-Script.xxxxxx line (it's different for everybody, for example xSDnsS for me) and then move to that directory: Step6 :- cd Hackintosh.Zone.Post-Script.xSDnsS ( <- this must be changed for your .xxxxxx ) and execute: Step7 :- ./postinstall 6. When it finishes just type: exit Screen hanging after login Set login to automatic if login hangs using -x to start in safe mode. Missing Bluetooth controller Transport error start with -s -v at "root prompt" type mount -uw / cd /System/Library/Extensions mkdir intel_back mv AppleIntelHD* AppleIntelF* intel_back/ touch ../ExtensionsReboot -v reboot Virtual box screen definition fix First log in to your mac install and locate org.Chameleon.boot.plist file that should be in the "Extras" folder Add or change the line that says <key>Graphics Mode</key> <string>1920x1080x32</string> Where "1920x1080x32" reflects the screen definition you want. You need to change it by opening a command prompt window then typing cd "C:Program FilesOracleVirtualbox" Then type vboxmanage setextradata "Name of virtual machine" "CustomVideoMode1" "1920x1080x32" Where "Name of virtual machine" is the name of your machine and "1920x1080x32" is the desired screen definition.
