This article applies to Suitcase Fusion 22 and earlier, running on macOS 12 Monterey and earlier.
When you open Suitcase Fusion for Mac you get an error dialog; clicking OK quits the application.
A file or folder that Suitcase Fusion for Mac is trying to use can’t be created, read, or written to. User permissions changes, macOS upgrades, and/or migrating user data between Macs may have caused unexpected system-level changes that Suitcase Fusion can’t reconcile as is, and will need to be addressed. Purging user preferences and letting Suitcase Fusion create a fresh set of preference files upon reopening the app can fix this.
Quit Suitcase Fusion and any open Adobe Creative Cloud applications.
Open Activity Monitor (located in /Applications/Utilities/).
Search for the process "FMCore", select the process name, click the X in the toolbar, then click Quit when prompted:
In the Finder, choose Go > Go to Folder.
~/Library/Preferences/and press Return.
Locate any files that begin with
com.extensisand drag them to the Trash.
Restart your Mac.
Relaunch Suitcase; you will need to make some basic preference selections and enter your Mac’s admin password to reenable the auto-activation plug-ins.
