“Suitcase Fusion has detected an incompatible version of FMCore. Suitcase Fusion can not continue.”


When launching Suitcase Fusion, this error message is displayed.


  1. In the Finder, choose Go > Go to Folder.
  2. Enter “~/.Extensis” (without the quotes) into the “Go to the folder” field and click the “Go” button.
  3. Drag the FMCore folder to the Trash.
  4. Launch Suitcase Fusion.

If you still receive the same error message, see Could not start FMCore.

Note: Our developers but a great deal of effort into addressing this issue in Suitcase Fusion 6. So far we have gotten very few reports of the issue in that version.
