    This from the Adobe Photoshop CS5 system requirements page:

    "1024x768 display (1280x800 recommended) with qualified hardware-accelerated OpenGL graphics card, 16-bit color, and 256MB of VRAM"

    Note that this is the general requirements to run the program, not for the GPU-accelerated features that need further support for Shader Model 3.0 and OpenGL 2.0.

    However, there's no explanation of what exactly is a "qualified" graphics card.

    It's been raised on John Nack's blog, but with no answer as yet (as of 13th April, John is "looking for more details").

    So, anyone any ideas? Does this mean for example that PS CS5 won't run on a Mac without a discrete video card (i.e. all Mac Minis, low end MacBook Pros, the MacBook, and low end iMacs)?

    The 256MB requirement would also seem to eliminate earlier aluminium iMacs with the 128MB cards and most of the white Intel iMacs.

    Any help much appreciated - thanks.

    Qualified should mean that it is supported by OpenGL.

    Apple has a list of the cards it supports for Snow Leopard (which has OpenGL), and they are:

    NVIDIA GeForce 9400M, GeForce 9600M GT, GeForce 8600M GT, GeForce GT 120, GeForce GT 130, GeForce GTX 285, GeForce 8800 GT, GeForce 8800 GS, Quadro FX 4800, Quadro FX5600

    ATI Radeon HD 4670, ATI Radeon HD 4850, Radeon HD 4870

    (http://www.apple.com/macosx/specs.html)

    ( To that add the new cards on the MacBook Pro's)...

    Every current Mac will thus be able to run PS CS5. So will all the "last-generation" Macbook Pro's. (NVIDIA 9400M)...

    The 256 MB VRAM speaks for itself. (I think all the supported cards have 256 MB anyway).

    Nothing strange here really. 256 isn't much at all nowadays; I don't think computers with less can be found on sale, with the exception of netbooks.

    So why is that a requirement now? How much more bloated can this software get?

    @*LTD*, @heyendo30 - Thanks for the clarifications. That's reassurance about the suitability of the current Mac line up. From the wording on the Adobe site, it seemed as if they were going to be deciding what is a "qualified" device.

    @decksnap: I can't figure out why this is included either; as I said there are further requirements for the GPU-accelerated features. Maybe there's an error and these graphics requirements are actually for the extra 3D / video features in Extended?

    If all this "bloat" is too much for you just use gimp or preview. ;)

    I'm looking forward to CS5 and its new features. Everything that makes my workflow faster is welcomed.

    Both of you are wrong.

    You are both listing the OpenCL cards, which is not OpenGL.

    Someone else will come out with what this really means, but if I had to guess, if you download GLView and have 100% support for 2.0 and have 256MB of VRAM then you're fine.

    As an example, my 8,1 iMac has a ATI Radeon HD 2600 PRO. It will qualify.

    I have been beta testing Photoshop CS5 on both my MacPro (2.66 Ghz quad Xeon with ATI X1900XT video card with 512 vram) and Macbook Pro 2.5 Ghz Core 2 Duo with NVidia GeForce 8600M GT video card with 512 vram).

    I can tell you that some advanced Open GL features in Photoshop CS5 are not supported by the ATI X1900XT GPU while it fully supports the GeForce 8600M GT GPU.

    What advanced features are you referring to? Anything worth the hassle of upgrading?

    I have the GForce 7600 GT with 256 Mb Vram. It's not on your Snow Leopard list, but I am still running Snow Leopard.

    What does this mean? That this card is "not really" supported by Snow Leopard and I cannot trust my colors?

    So this means I won't have trouble with my G-force 7600 GT?

    But I have to download this particular software from the source you gave to be able to run Photoshop CS 5 ( on 24" iMac with Core 2 Duo)?

    Can you elaborate on what advanced features aren't enabled?

    Isn't it interesting whenever a software update is released with additional or improved features, there are always knockers willing to complain the software is bloated. What difference does it make. If you want the extra features, buy it. If you don't need them, stick with your current version

    When OpenGL is enabled in Photoshop CS5, there are 3 selectable modes available. Basic, Normal and Advanced.

    Basic - This mode used the least amount of GPU memory and the most basic OpenGL features. Use this mode when experiencing visual defects or general slowdowns in your document window or when running other applications that preoccupy the GPU.

    Normal - THis mode uses a large amount of GPU memory and advanced OPenGL features to perform color matching, tone mapping and checkerboard blending. This frees the CPU to perform other tasks but may cause visual defects on some GPUs.

    Advanced - This mode is the most GPU intensive. It uses the same amount of memory as the Normal mode while enabling more advanced techniques to improve drawing performance. This may cause visual defects on some GPUs.

    The ATI X1900XT is only supported in Basic Mode while the NVidia Geforce 8600M GT is supported in all three modes.

    Thanks. I'm guessing this is more about having the ability to offload processing to the GPU rather than losing functionality in the app?

    For example, I'm on an old 7300 GT, so I have no doubt I'd be stuck in the Basic mode. But from a features standpoint, I'm guessing I can still do everything I need to in PS, it's just I have to rely on the CPU for everything. Sad that Adobe really dropped the ball on Multi-threading in CS5....guess they are putting all their eggs in the GPU basket.

    I don't do 3D renders or anything fancy in PS.....I just use it in web development and photo touchups. I love the features in CS5 that I'm seeing so far....the one thing I'm not happy with is the upgrade pricing from CS3 (http://forums.macrumors.com/showthread.php?t=901248). :mad:

    Which mode would the 7600GT be able to run? It has 256 Mb of RAM.

    Not really, for example InDesign is now multi-threaded so you can continue working while writing pdfs. I'm really looking forward to this and it will obviously work on any intel dual-core machine.

    OK, this makes sense and is similar to the situation with PS CS4. For CS4, I found three Adobe KB articles - see here for a list of tested graphics cards, here for a list of features available with specific cards / amount of VRAM, and here for some known issues with specific cards.

    So presumably what we need now from Adobe is a similar definitive list of GPUs for PS CS5 and their test findings. Because, whereas the sys reqs for PS CS4 only mention graphics cards for the GPU-accelerated features, the PS CS5 sys reqs seem to say that the app will not run at all without a "qualified" card - and (as yet) there's no defined list of what they are.

    The NVidia 7600 GT for Mac wasn't even mentioned.

    Not sure if this is a good thing. ;)

    Here's some details on the OpenGL support:
    http://kb2.adobe.com/cps/404/kb404898.html#mac intel

    Just installed CS5.....my old 7300GT is supported since I'm on 10.6.3, but only in basic mode. I'm fine with that....didn't really expect anything more since it's an older card.

    I got a Nehalem MacPro with the ATI Radeon 4870 and OpenGL does not work. Photoshop CS5 does not recognize the card... :(

    Photoshop CS4 works fine though.

    Hopefully Adobe will give out more detailed information.

    My 7600 GT is in an iMac - not exactly easy to exchange. And exchange with what?

    I'm running PS CS5 extended on my 1.83GHz (ATI Radeon X1600) Core Duo iMac.
    The only difference I can tell is I'm only able to use Basic mode for OpenGL Drawing.

    Thanks for the recent responses folks. Some interesting points.


    Thanks - so this is Adobe's equivalent to the CS4 supported list that I'd found (but see below).

    This is worrying - firstly the KB article that kbmb posted lists the "ATI Radeon 4000 series" as tested (presumably a 4870 is part of the 4000 series, unless ATI do something strange with model numbers/series), and secondly this is a current model professional Mac desktop with an upgraded BTO card.

    Again, presumably a Radeon X1600 is part of the "X 1000 series", which Adobe list as "no longer being tested"; however you've proved that it does work. It's also only got 128MB VRAM, contrary to the Adobe sys reqs which state a minimum of 256MB.

    So far, it appears that PS CS5 will run successfully (albeit with GPU acceleration limited) on a 4 year old original iMac, a 2 year old MacBook Air (the GMA3100 is listed as tested), but not with OpenGL on a current Mac Pro - which seems crazy.

    Personally, I'd be interested to hear from anyone successfully running PS CS5 on a Mac with a 9400M. The 9000 series is listed as tested by Adobe, but with the above experiences, I'd be grateful for some user experience. Thanks.

    EDIT: Just to clarify, I'm still about to upgrade my old G5, so unfortunately I can't install the CS5 trial myself. Hence my interest in whether PS CS5 will run on a 9400M system, before I go and buy a new machine.
