poispois Posted November 14, 2013 Share Posted November 14, 2013 My card in 10.9 DP1 - DP6 works perfectly, but i have problems in stable 10.9 - my card is recognized as 7xxx and i have not full QE/CI Can anyone help me? Thanks! You need to choose the correct framebuffer for your model. For me it was Dashimaki and using miniDVI. Check this thread for more on how I got it working right: http://www.insanelymac.com/forum/topic/292647-no-video-playback-on-hd7770/ Hey I installed Mavericks using this torrent: http://thepiratebay.sx/torrent/9086005/OS_X_Mavericks_10.9_bootable_USB_for_Intel_PCs_%2813A603%29 Everything works fine (ie. audio, network) except I cant boot using my ATI 7870 Sapphire card!

Rebuild your caches and repair your permissions. That should do the trick. Link to comment Share on other sites More sharing options...

poispois Posted November 14, 2013 Share Posted November 14, 2013 how do i "Rebuild your caches and repair your permissions"? with kext utility or something? so i just leave all the ati kexts intact? thx! I use Kext Utility. It repairs permissions and system caches on launch even if you're not going to install a kernel extension. Im Using Clover. Standard install. it recognizes the GPU, QE is working, but the performance is very poor. How can i enter ati personality, Framebuffer, etc using Clover configurator? Tks a zillion I also use Clover. You can find that information on the thread that I pointed you to. If you're not into fiddling with text files you can use Clover Configurator. That's what I used in the beginning. But be aware that it's a process that takes it time, I've managed to get the card properly recognised after "many" attempts.

hugeschnauzer Posted November 18, 2013 Share Posted November 18, 2013 You still do not have the correct frame buffer selected. Is there a way to do it using Chameleon? Will it speed up the 7970? Link to comment Share on other sites More sharing options...
BuXb Posted November 29, 2013 Share Posted November 29, 2013 Is there any experience w/ the Sapphire 100357LP Radeon HD 7750 1GB 128-bit GDDR5 PCI Express 3.0 x16 HDCP Ready Low Profile Video Card mDP/ DVI-I/ HDMI in Mavericks? Got very good reviews on Amazon and NewEgg. My Optiplex 745 SFF (Small Form Factor) and a 27" mDP ACD are looking for a new low-profile mDP video card, and the 7750 is said to groove along just fine with the PSU. Now I'm wondering about Mavericks compatibility. Link to comment Share on other sites More sharing options...
