Article on Radeon 7950 with 3 Displays updated for OS X 10.9.3 follow-up
Updated the page on incorrectly reported display rez w/10.9.2 with Dave's notes after installing 10.9.3. (Upgraded over a 10.9.3 beta.) Also has links to Apple docs on Multi-Display setup/info.
Saw a reply to an Apple forum post on OS X 10.9.3 breaks MacPro D700 GPU for Adobe CC and Resolve links to an Adobe forum post that suggested replacing the video card(s), claiming some early builds may have had flaws (?). The question of course is if the vram/card was suspect, why didn't the problem appear only after updating to OS X 10.9.3. (Granted many have had various display problems with Mavericks in general, even before 10.9.3.) Unless the 10.9.3 update enabled a feature/hardware acceleration which increased GPU load and triggers a problem. (Or just introduced bug(s) that trigger it.) Also odd was the comment about 'replacing the card' (not both?) and a comment it took 18 hours to replace, unless that was just his turnaround time. But if any other Late 2013 Mac Pro owner can confirm a card replacement (under warranty) for problems like this, . TIA.
Update - here's a reply from a reader to the above:
"Regarding OS X 10.9.3, Adobe ME CC on Late 2013 Mac Pro
Just a note that I haven't seen any problems encoding with Adobe Media Encoder CC and 10.9.3 on my 8 core D700 nMP with 64 GB. I received this unit in early January. It's currently hooked up to an Asus 32" 4k display, a 24" Apple LED Cinema Display, and a Seiki 39" 4k TV.
To be fair, all I am doing is encoding H.264 using it with ProRes HQ source files. I have openCL ON. No issues. I am currently editing with FCPX 10.1 which also shows no issues. (I encode h.264 with AME because it's a lot faster than Compressor or FCPX, and looks better; FCPX export to ProRes only is however fast.)
Of note: Davinci Resolve (I tried three versions) does crash my machine hard using 10.9.3.
