Do I have to get all new apps if I convert from PowerPC Mac to Intel?

    If you're changing to an Intel Mac running 10.6.8 or earlier, no. If it's running 10.7 or newer, yes.

    Welcome to the Apple Support Communities

     

    Not all of them, because Universal apps will work on your Intel-based Mac. However, if you get a new Mac with OS X Lion or Mountain Lion, you won't be able to run your PowerPC apps anymore because Rosetta isn't compatible with those OS X versions.

     

    If you get a Mac with Mac OS X Leopard or Snow Leopard, you will be able to get Rosetta and use your PowerPC apps

    Hmmm,

    I have Adobe Illustrator CS2 and thought I could upgrade it to CS5 and then move it to a 2011 Mac Mini (Lion) ?

    According to the Wikipedia entry for "Rosetta," Rosetta can't deal with big apps like Photoshop. From Adobe, I found out that CS3&4 will run on Intel Macs running OS 10.5 Leopard, and CS4,5&6 will run on OS 10.6 Snow Leopard. I hope both sources are accurate.

    FYI,

    I am running Adobe CS3 and CS4 on Intel Mac running OS X Snow Leopard 10.6.8.

    Runs great on 16 GBs of RAM

    Could you provide me a link to support that statement; thanks!

     

    I use Adobe Creative Suite 2 with Rosetta in Snow Leopard installed into Parallels, so I have continuing access to these programs, as needed, in Lion:

    but they perhaps loosely paraphrase " How compatible your application is with Rosetta depends on the type of application it is. An application such as a word processor that has a lot of user interaction and low computational needs is quite compatible. An application that requires a moderate amount of user interaction and has some high computational needs or that uses OpenGL is most likely also quite compatible. One that has intense computing needs isn’t compatible. This includes applications that need to repeatedly compute fast Fourier transforms (FFTs), that compute complex models for 3-D modeling, or that compute ray tracing."  as including Photoshop among apps that have " intense computing needs " - maybe the wiki author found that to be the case on an older machine?.

    That Wikipedia entry should be updated. CS3 runs fine in OS 10.8. I use it just about everyday. And Adobe says that too. I could find the link, if you need it to argue with them. Adobe does say they do not support CS 3 because it is too old, but they do also explicitly say "there are no known issues" with CS3 and Mountain Lion. I can vouch for that.

    Very loosely!  Actually that quote from Wikipedia is wrong with regard to Adobe Photoshop and should be corrected (at least as it applies to version 9, CS2, after which, later versions, starting with CS3 do not need Rosetta in any event).

     

    While I am not sure about the rest of that quoted phrase (acually in most of my posts on this forum indicating my solution for running PowerPC applications [Installing Snow Leopard with Rosetta into Parallels] in Lion or Mt. Lion, I do note: "Computer games with complex, 3D or fast motion graphics make not work well or at all in virtualization." I do, however, see this as a virtualization problem and not a Rosetta problem (as opposed to these programs running on a computer that can actually boot into Snow Leopard and run these programs in emulation, where Rosetta should not pose a problem).

     

    My experience with Adobe Photoshop is limited to CS2, which is now available for free download from the Adobe website.  My uses for this program are limited, such as when one frustrated Mt. Lion upgrader noted that Apple should post a flag about the loss of Rosetta (see my graphic posted above).

     

    But my understanding is that Adobe Photoshop (at least up to version CS2) does not require any rendering, which could be hampered and slow in virtualization and perhaps additionally with Rosetta. 

     

    Use of Photoshop 9 (CS2) appears to be similar to use of Freehand MX and none of the users of either of these powerpc applications have come back with any complaints after my suggestion to them on how to continue to run these powerpc apps in Lion or Mt. Lion.
