rainmaker3 Posted December 26, 2014 Share Posted December 26, 2014 Hello, My specs are : CPU : AMD FX 8320 GPU : Sapphire Radeon 280X MoBo : Asus M5A97 r2.0 I have succesfully installed Yosemite on my pc. I used the Bronya rc2 kernel and a post-installation utility by a "commercial spin-off of the OSx86 scene" and I also installed FakeSMC. Now I boot with -v and I see this error : Warning: couldn't block sleep during cache update Warning: proceeding w/o DiskArb and it gets past the console all the way to the grey screen. It gets stuck there with the spinning wheel on my mouse. No Apple logo, no loading bar, just a blank grey screen with the spinning wheel. It boots up in safe mode and I tried reverting some kexts from 10.9.5 but no luck. I reverted AppleACPIPlatform.kext, IOACPIFamily.kext, IONDRVSupport, IOPCIFamily.kext, IOUSBFamily.kext, Corecrypto.kext, Sandbox.kext, System.kext in that order and rebooted every time. Once I got to the System.kext things got too weird with multiple errors (mostly ACPI) so I stopped there. When I had tried to install Mavericks updates I got the same thing. No error message though. Reverting these to an earlier version (10.9.0) worked. But now it doesn't. Anybody got any ideas? Link to comment Share on other sites More sharing options...
BNZfive Posted December 27, 2014 Share Posted December 27, 2014 Yosemite requires booting with flag kext-dev-mode=1 in order for FakeSMC.kext to load 1 Link to comment Share on other sites More sharing options...

Codinger Posted February 27, 2015 Share Posted February 27, 2015 For getting r9 2xx working try to install clover to efi partition. (Note that EFI must be FAT32) Link to comment Share on other sites More sharing options...
simru Posted March 31, 2015 Share Posted March 31, 2015 add -f.... it will probably work.... anyway boot in safe mode and replace iopcifamily and appleacpiplatform (find out Carlo_67 kext's in download section) and install amd webkit. reboot and add -f Link to comment Share on other sites More sharing options...

Try this guide, it worked for me each time I have installed Yosemite. http://www.insanelymac.com/forum/topic/304513-fixguide-amd-stuck-at-greywhite-screen-with-spinning-beachball/ Link to comment Share on other sites More sharing options...
(AMD)ConanHUN Posted July 6, 2015 Share Posted July 6, 2015 I have a simple fix for this: add msibase=0x90 to boot flag Link to comment Share on other sites More sharing options...
