MasterofPuppets Posted December 3, 2015 Share Posted December 3, 2015 (edited) I have Yosemite Zone somewhat installed. After install, it would boot into a gray screen with the mouse pointer on the top-left corner. About 10 seconds into that, I'd get the spinning beach ball and it wouldn't go past that screen. I rebooted my computer and typed in "-x", and it went straight into the setup assistant where I created my user account and other information. After that, I rebooted the machine, and started OS X without any additional boot flags. Again, it went into the gray screen with mouse pointer and beech ball. At this point, I suspected that it was graphics card related. I once more rebooted my machine, and this time, I typed in "-s" to get into Single user mode. I did the grafix backup all command, and rebooted the machine. At this point, the machine boots into OS X, but with graphical issues. "About this Mac" says Graphics: Display 3Mb and that's it. I've read that the Yosemite has out of the box support for R9 380 cards, but for some reason, it doesn't work well with mine. I'm also under the impression that the AMD9000Controler.kext file is what works for this card. I've used Kext Wizard to install that kext, but still nothing. I appreciate any help. Hardware info is in signature. *Edit 1* It looks like I forgot to include the AMDSupport Kext. I installed that through Kext Wizard, and after rebooting, my graphics card is now detected as AMD R9 xxx 4096MB However, I still have some graphic glitches. I moved the System Report window around the screen, and there's obvious jerking/tearing. Also, when I go to sign in, the screen flashes a bit, and then signs in. Here's a link to images I took about the issue: https://flic.kr/s/aHskmQwW2g *Edit 2* I installed the AMDRadeonVADriver.bundle file and it seemed to help a little. The animations are still laggy, but not as much as before. There's still some jerking/distortioning when I move a window across the screen, but it isn't as noticeable as it used to be. And again, there's no dock transparency. My computer is identified as a MacPro6,1, which is the trash can model Mac Pro, so it should support the transparency, right? However, there's still some lag going on. If you can't see my signature: CPU: AMD FX8350 @ stock speed Motherboard: Gigabyte GA-990FXA-UD3 Rev.4 RAM: 8GB (2x4) Patriot Viper @ 1600 Mhz Graphics Card: MSI R9 380 4GB Storage: 1x 250GB SSD (Windows 10), 1x 64GB SSD (OS X 10.10.1) 1x 2TB HDD (Storage for WIN 10) 1x 160GB HDD (Storage for OS X) PSU: Corsair CX750 non modular Edited December 6, 2015 by MasterofPuppets Link to comment Share on other sites More sharing options...

MasterofPuppets Posted December 6, 2015 Author Share Posted December 6, 2015 Revert the kexts back to the default ones and try installing these, http://www.insanelymac.com/forum/files/file/354-amd-replace-kext-for-yosemite/ Someone reported they help out with AMD cards. I tried that and it didn't really help with the graphics issue. However, it did fix my Ethernet problem. It kept telling me that there was a cable unplugged, but now that's fixed. The graphics issue is not all that obvious until I open the Applications button or when I drag a window across the screen. I suspect that it is some kext conflict, but I'm not sure. Like I said, About this Mac identifies my graphics card as AMD R9 xxx 4096 MB. Link to comment Share on other sites More sharing options...
