I've so far tried three different methods for creating a bootable Yosemite installer, with varying failures:

 

http://www.insanelymac.com/forum/topic/298753-boot-usb-os-x-yosemite-chameleon/

Result: I get stuck half way through boot, with 'Waiting for root device'. http://www.insanelymac.com/forum/uploads/monthly_07_2014/post-1188792-0-44397500-1406549178.jpg

 

http://www.insanelymac.com/forum/topic/299865-clover-v2k-r2780-special-edition-yosemite-beta/

Result: Is not even recognized as a proper boot device. I only get the message: 'Insert proper boot device and press any key to continue'

 

http://www.insanelymac.com/forum/topic/298521-easy-yosemite-1010-usb-installer-updated-public-beta/

Result: Is not even recognized as a proper boot device. I only get the message: 'Insert proper boot device and press any key to continue'

 

What am I doing wrong here? Hardware specs in my signature, and for your information I'm using a 16GB Transcend USB 3.0 stick as boot device.

 

Any help would be greatly appreciated, would love to give Yosemite a shot!

Alright, I have now gotten past the installer (had to use -x, otherwise I would get a kernel panic). However, when booting from my freshly installed drive, I can´t seem to avoid a kernel panic.

You use a same bootloader or not.Maybe problem in bootloader.Do you have a NullCPUPowerMangement.kext?

Put your USB on USB 2.0 port and use a org.chameleon.boot.plist Ive corrected....Yes and put your smbios to iMac13,2....

Stuck at 'Missing Bluetooth...' now, trying to work out my graphics issues. At least I'm making progress!


Hm, seems my graphics card is having some issues. Tried combinations of -x, GraphicsEnabler etc, but booting stops at 'Missing Bluetooth...'. Any ideas how to solve it?
