Solution
Try these troubleshooting steps in order; if you continue to have problems, you can submit a support request and Technical Support can help you.
Letting the type core start before opening Suitcase Fusion
The type core (the background process in Suitcase Fusion that activates and deactivates fonts) may not be started completely when Suitcase Fusion tries to connect, so it can't respond properly. Close Suitcase Fusion, wait 5 to 10 seconds, and open it again.
Removing Suitcase Fusion as a login item
If you set Suitcase Fusion as a login item in macOS, it may open before the type core has started completely. There's no way to set login items to start in a specific order; remove Suitcase as a login item and open it after you've logged in to macOS.
- Control-click on the Suitcase Fusion icon in the Dock
- Uncheck Options > Open at Login
Reopening windows when logging back in
Recent versions of macOS will ask if you want to reopen windows when restarting your Mac. This works in a manner similar to a login item; when restarting your Mac, uncheck "Reopen windows when logging back in" before clicking Restart.
Removing outdated temporary files
Sometimes, Suitcase Fusion can't find the type core process because of outdated or damaged session information. In these cases, waiting before trying to open Suitcase Fusion doesn't address the issue.
- In the Finder, select Go > Home
- Press Command-Shift-period; the Finder now displays hidden files and folders
- Drag the .Extensis folder to the Trash
- Open the Library folder, then open the Extensis folder
- Drag the com.extensis.FMCore-LaunchInfo.conf file to the Trash
- Press Command-Shift-period to make hidden files and folders invisible again
Repairing a damaged or incomplete hosts file
An incomplete or damaged hosts file will cause Suitcase Fusion to be unable to find a running type core process. For more information about fixing the hosts file, go to Getting FMCore error 67112974 when opening Suitcase Fusion for Mac.
