If you are getting this error when you try to start Photoshop on Mac OS, it most likely indicates one of two things:

- Your Mac has an older PowerPC processor.

To check your processor, click the Apple menu and choose About This Mac.

If you have a PowerPC processor, then you will not be able to use Photoshop on this system. You will need to use it on a newer Mac that has an Intel processor.

- The Photoshop application is incomplete/damaged, most likely due to a failed installation attempt.

To repair the installation:
1. Quit all applications.
2. In the Finder, navigate to the /Applications folder.
3. Back up any files as needed (e.g. custom plug-ins) from the Photoshop application folder (e.g. /Applications/Adobe Photoshop CS5.1/), and then drag this folder to the Trash.
4. Empty the Trash.
5. Start the installer for Photoshop your edition of Adobe Creative Suite.

* If you purchased boxed software, then insert the installation disc into your computer's optical drive. (If the installer does not start automatically, then navigate in the Finder to the installation folder (e.g. "Adobe CS5") on the installation disc and double-click Setup.)
* If you purchased downloadable software from the Adobe Online Store, then double-click the installer that you downloaded. (If you no longer have the downloaded installer, then log into your account at www.adobe.com/membership to download the installer.)

6. In the installer window, select Adobe Photoshop in the list of Installed Products.
7. (Optional) Deselect all other components besides Photoshop, if other options are available.
8. Click Install. Follow the on-screen instructions.
