macOS Mojave – How to Get Old Apps Like Photoshop CS5 to Work

adobe-photoshopapplicationscompatibilitymojavesoftware

On the weekend I upgraded my MacBook Pro to macOS Mojave. Things are mostly ok but I have some apps that no longer work. The one I’m most stressed about is Adobe Photoshop CS5. When I try to run it it refuses to open.

I've tried resetting NVRAM and running Disk Utility, but this didn’t resolve the issue.

Before I take the plunge to revert back to macOS High Sierra I thought I’d try my luck here.

Do any of you folks have any other suggestions for me to try first?

The first thing I would try is changing the security and privacy settings in System Preferences. You can do this as follows:

  1. Go to Apple > System Preferences…
  2. Click on Security & Privacy
  3. Select the Privacy tab at top right
  4. In the lefthand pane select the Accessibility option
  5. At bottom left of the window make sure the padlock is unlocked (if not, select it and enter your password)
  6. In the list of apps on the right-hand side, make sure Photoshop and any of the other apps you’re having problems with are ticked
  7. OPTIONAL: If any apps you’re having problems with are not listed, click on the + button under the list and navigate to the apps to select and add them to your list. Once done, then repeat Step 6
  8. Make sure you lock the padlock again that you unlocked at Step 5
  9. Quit and restart any apps you’ve just allowed to control your Mac (i.e. if they were already open)

Now try running Photoshop etc again to see if they work.
