  • Mac Pro Owners Continue to Experience Issues


    Just one year after the release of Apple’s redesigned Mac Pro, the device continues to remain a frustration for many video-focused professionals whose workflows are being interrupted by rendering glitches apparently caused with the unit’s ATI graphics system. The problem tends to center primarily around OpenCL-driven color corrector DaVinci Resolve, which first began to appear in May of this year, manifesting as application lockups and visual artifacts on exported video. At the time, Apple’s OS X Mavericks 10.9.3 was blamed but problems seemed to have continued even after the release of OS X Yosemite.

    An AppleInsider user by the name of “OpenCL LSD” wrote the following regarding the matter:

    I and others have reported this to Apple, yet they are quiet on the issue. I first reported it to Apple in late September. Since then they requested AppleCare replace the graphics cards three different times which did nothing to fix the issue.
    Although the cause of the issue continues to remain a mystery, a number of threads on both Apple’s own support forums and those owned by DaVinci creators BlackMagic Design points to the device drivers supplied for the Mac Pro’s ATI FirePro D700 graphics cards. Many users have reported that restarting their Mac Pro into Windows using Bootcamp resolved the problem but the fix isn’t the optimal solution to their workflow. BlackMagic user, Edo Brizio, wrote the following regarding the matter:

    Yes, I confirm that installing Windows 8.1 on my MAC PRO and running Resolve 10.1.5 solves the render issues. Resolve sees the 2 D700 as 2 Radeon HD 7900.
    Other users are claiming that thermal problems could be to blame with some resorting to software tricks that force the Mac Pro fans into high gear. Others are saying that they went as far as constructing elaborate cooling modules around their towers, both of which appear to have helped ease the issue. According to Apple forum poster Alex Sylicone:

    Seems heating problems ... we made a "box" with two fans (one under the mac to flow and one over to aspirate heated air) and ... miracle, most of our problems are solved.
    BlackMagic employee, Peter Chamberlain said the following in a post regarding the matter:

    There are a number of people looking into these reports. I'm hopeful of an update from those engineering teams shortly. As mentioned above we don't see this in our lab but I have seen some of these at a customers facility. In the meantime, I have reports that the latest Yosemite update helped with one of the problems so be sure to you are up to date with that.
    Apple seems to be treating the problem reports as possible hardware concerns with numerous users reporting that the company readily replaced GPUs and logic boards in affected units. Some users are reporting receiving multiple replacements with Apple technical support acknowledging a possible software problem for the third incident. Although only a few dozen complaints have surfaced, this marks the latest in a string of incidents, notably including the disastrous rollout of Final Cut Pro X, which has seen much of the professional video community lose faith in Apple.

    We’ll have to see if the issue is resolved going forward but as of right now, no clear answer has been given.

      While nobody is sure what the deal is yet, it wouldn’t surpise me in the least if the heating issue was down to this stupid ever increasing quest for miniaturisation on the part of Apple.
      Stupid Tim. Go with the Tower design by all means but why so small? I’d prefer a slightly bigger tower if it meant I could have a better cooling system.

      ATI has been going downhill for a long time. There is a reason why Nvidia has been #1 for so long. And a lot of it has to do with the fact that you can actually install nvidia drivers. 80% of the time, driver installs fail with ATI cards.
