nlbailey Posted December 16, 2011 Share Posted December 16, 2011 Haven't been able to find anything definite on this card. Anyone have it working in lion / link to post or instructions? Looking to purchase a new card and found it for a good price. Thanks!

Mine got one DVI port working only and its RAM size is wrong (should be 1024MB instead of 1536MB) Link to comment https://www.insanelymac.com/forum/topic/273568-geforce-gtx-550-ti-lion/#findComment-1780178 Share on other sites More sharing options...
Edkroket Posted December 21, 2011 Share Posted December 21, 2011 I have all ports working but audio I don't know I don't use it. I play movies from my Hack on my tv trough HDMI and sound comes from my Hack with that. Never used audio trough hdmi but I think it should be possible I've seen topics here about that. Use the latest Chamera bootloader and add Graphics enabler to Yes, don't use GraphicsMode! And do not use ATY_init or something like that. Here is a good start for your card. http://www.tonymacx86.com/viewtopic.php?f=15&t=35148&hilit=AppleGraphicsPowerManagement.kext+edit Ed Link to comment https://www.insanelymac.com/forum/topic/273568-geforce-gtx-550-ti-lion/#findComment-1780182 Share on other sites More sharing options...
