OS X El Capitan | Do Not Upgrade (Yet!)

Grant Hodgeon
Heed this warning all that want to play with the latest and greatest.

I always like to keep abreast of compatibility issues and have a test system dedicated to tinkering and El Capitan just landed on it. Capture One initially opened and loaded a job, processed a few files (was aiming to see if Metal's intro into OS X also improved the workload on the GPU and ultimately processing speed improvements.) Alas the job no longer opens and no sessions can be freshly created. As expected, currently incompatible

Take this warning, do not upgrade to beta software on production equipment. I know this question with every new OS release gets the typical questions on this forum. The answer is to not upgrade your OS on a Capture One critical machine until Phase-One announce official support.

Cheers!

    Thank you very much for staying on the cutting edge and letting us now before we jump in. ðŸ‘

    Hey Grant,

    Did you get to run some benchmarks? I'm also curious about how Metal will improve performance, although I guess we will have to wait for Capture 9 for any real difference.

    I'm still running 10.9.5 on my systems, is 11 fully stable now especially on the new Mac Pro? Hesitent to upgrade...

    Actually averaged ~10 seconds slower on a roughly 2 minute processing job but I wouldn't chalk that up to anything conclusive. Was simply hoping there would be more GPU resources if redraw performance in the OS was improved - which it has. Slightly. Exciting times ahead for those with 13" MBP Retina's with poor redraw performance.

    This could also (long shot) allow 60hz on 4/5k displays connected to the MBP

    Excited and hopeful Phase One will integrate Metal into future releases.

    Just to be clear, Metal on OS X will not accelerate anything that has not been coded to take advantage of it. Existing builds of C1 will not see the benefit of Metal. The examples shown by Adobe however point to very significant improvements in the kinds of tasks that C1 also uses so this is potentially very exciting for the future of imaging software in general and C1 in particular.

    There seems to be a bug in the forum which caused this post from me to appear as though NNN63496970495155228 was the poster. It appeared as though I was logged in as him even though I would have no way to do that.

    If you are testing (on a dev box), Option while launching may be your friend. Turn off all OpenCL and go from there.

    The latest built of El Capitan invites me to trash Capture One which is dangerous for my Mac. 😄

    Partially true.

    Whilst C1 won't directly receive any acceleration due to Metal -- The OS UI will benefit. This free's GPU Resources and in turn should allow a slight performance boost in rendering/processing.

    It's been discovered that whilst the beta of El Capitan is snippy snappy fast, the UI is still not being rendered on Metal so there's performance improvements yet to come.

    I haven't been more excited for an OS Release since X.

    OS X El Capitan is Beta Software and if I am not totally wrong, it is not allowed to discuss
    those issues in public - I guess it is a good idea to read apples rules for beta testers.

    Grant,

    Even by typical forum standards where every statement will be relentlessly nit picked, that's a stretch. The amount of performance boost from those 'freed up' GPU resources will be very "slight" indeed. 😉

    Yeah, no one should expect any performance gains without optimizations made to specific apps.

    The examples shown by Adobe however point to very significant improvements in the kinds of tasks that C1 also uses so this is potentially very exciting for the future of imaging software in general and C1 in particular.


    The sad thing is that C1 could do a lot to improve performance without Metal. You simply have to play around making adjustments in the latest Lightroom CC 2015 on a Mac to see what's possible. It makes C1 look like a dog on 10.10.
