Mac OS 10.13.6
Photos 3.0
Aug 27 2019

My Mac photos was app was running slow so I rebuilt it and it's a lot faster, but ...... a problem.... under extensions I he pixelmator, pixeplmator pro and pixelmator touch but none of them will load now when I select them from the edit menu,

The error message I get is 'The file couldn't be opned because it doesn't exist'

I imagine I need to delete these extensions and redownload them, if so how? Any help will be appreciated.

I'm not sure what exactly could be going on, but you can try this to remove any remaining extension data and 'reinstall' them:

1. Quit the Photos app (if it's open)
2. Open Finder
3. Choose Go > Go to Folder and paste the following path:


4. Find the following folders:

5. Move all three to the Trash and empty it
6. Open Pixelmator and Pixelmator Pro
7. Go to System Preferences > Extensions > Photos Editing and make sure the Pixelmator extensions are turned on

If that doesn't help, it'd be great if you could get in touch with us about this at
