passmaster16 Posted June 4, 2014 Share Posted June 4, 2014 Hi All, I'm trying to install 10.9 Mavericks on a Sony Vaio (sve1712bcxb https://docs.sony.com/release/specs/SVE1712BCXB_mksp.pdf) without much success. I have created a Clover R2689 EFI USB drive per the following http://rampagedev.wordpress.com/os-x-10-8-mountain-lion/ using Mavericks from the App Store. I have ensured that the Sony Bios, which is severely locked down, does have UEFI enabled and Secure Boot disabled. I have tried using the USB drive in various USB 2.0 ports on the machine. When I attempt to boot from the USB drive, I get "Waiting on <dict ID="0"><IOProviderClass</key>... followed by Still Waiting For Root Device message (see attached for screen capture). I have tried various bootargs per the guide including -v cpus=1 npci=0×2000, -v npci=0×2000, -x -v, -v GraphicsEnabler=no, USBBusFix=Yes, etc. I'm sure I'm missing something simple here so any insight would be greatly appreciated. Thx Josh Link to comment Share on other sites More sharing options...

Thx Josh USB problem. Try a different USB stick, different USB options in BIOS, or add GenericUSBXHCI.kext to the kexts you're injecting. Link to comment Share on other sites More sharing options...
passmaster16 Posted June 9, 2014 Author Share Posted June 9, 2014 Thank you RehabMan, adding the GenericUSBXHCI.kext to the kexts>10.9 folder did the trick Link to comment Share on other sites More sharing options...
