Having successfully installed OS Lion onto my iMac Intel, I have just tried to open Adobe Illustrator CS and get this message:


"You can't open the application Adobe Illustrator CS because PowerPC applications are no longer supported."


Any ideas because a lot of my work is in Illustrator file format.

iMac Intel 24", Mac OS X (10.6.6), iPad, MacBook Air, iPhone 4

    You will i'm afraid have to upgrade your copy of Illustrator (and any other PPC applications)

    I got the same problem as you actually... And I'm confused how I get my work on AI and PS.

    Rosetta, the bit of code that allowed PowerPC applications to run on the Intel platform, is no longer a part of Lion.  Apple abandoned the PowerPC architecture about six years ago.  They provided Rosetta to allow users to continue running applications which were developed for the older hardware.  At some point, they were going to have to drop that support and rely on users to upgrade to versions compatible with the Intel architecture.

    But it was in the info that Apple gave with Lion: it is not supporting Rosetta (PPC) any more!

  • John Hammer1 Level 4 Level 4

    Sorry, but those applications which relied on a Mac with a PPC processor or Rosetta will not work under Lion. (Lion cannot be installed on a PPC Mac, and Rosetta is not included with/will not run under Lion.)


    Buy an external hard drive and load it with the latest version of Snow Leopard. Then whenever you want to play those games or use other older PPC software, reboot to Snow Leopard on the external drive. You can do this with a partition of your internal drive, also.

    JH, can you go into a bit more detail on how to install Snow Leopard on an external?? And instructions on how to operate?


    Very much appreciated!

  • John Hammer1 Level 4 Level 4

    Installing Snow Leopard onto an external drive isn't very much different than installing it onto your internal drive over your current OS.


    First, buy the Snow Leopard DVD. Apple and many retailers sell it for about $30.


    When the DVD arrives (or you get home from the store with it), run whatever system maintenance you're comfortable with (Verify/Repair Disk and Repair Permissions using Disk Utility at the very least) and then back up your hard drive. I suggest both a full bootable backup onto an external hard drive plus a separate backup of your most important data (purchased music and movies and other media, your dissertation and other text files, etc.) on some external drive or removable media such as writeable CDs or DVDs.


    When the backup is complete, connect your blank external hard drive (NOT the one you used for your bootable backup!), then insert the Snow Leopard DVD. Find the "Install Mac OS X" icon (it might have a slightly different name) and double-click it to get the installer started. When it asks you to choose the disk onto which to install Snow Leopard, select your external hard drive. The rest is fairly automatic.

    If you need PPC applications you'll need to use Snow Leopard, Leopard, or Tiger.


    1. Open disk utility and select your hard drive.

    2. Go to the partitions tab, add a new partition with the + button. You'll need to determine how much space you'll need for SL. Aptly name it.

    3. Open the Snow Leopard installer, select the new partition for your install.


    Also you can open most Adobe Illustrator files in Preview for viewing but not editing.

  • John Hammer1 Level 4 Level 4

    Backup first if you do a live partition of a drive that isn't blank.

  • Moop_stick Level 1 Level 1

    That's not really necessairy (it's good to do, but Disk Utility won't ruin a disk). Boot Camp Assistant and Disk Utility have never ruined a partition for me. Once I had a kernel panic during repartitioning. I only had to run the repair disk function to fix the disk's bitmap.


    Installing Lion will repartition your disk anyway.

  • John Hammer1 Level 4 Level 4

    It's insurance. I'm glad to hear that you haven't had a problem. It's unlikely that anyone will. But partitioning a drive which already has data on it - data you don't want to lose - is the most likely time that something will go wrong due to a confirmed action of the user. Backing up is something one ought to do regularly, anyway. Running one just before a relatively risky action like a live partitioning is a good idea, even if the chance of a problem is low.
