Suitcase Fusion compatibility with OS X 10.8 Mountain Lion
July 31st, 2012 by Jim Kidwell
With the latest and greatest OS X update now out in the wild, many of you are making the jump to upgrade your systems.
Suitcase Fusion 4 is compatible with Mountain Lion 10.8.
For full Suitcase Fusion compatibility information, including OSes, plug-in support for the Adobe Creative Suite and QuarkXPress, see the Suitcase Fusion compatibility page.
Notes about upgrading to Mountain Lion:
- Before installing Suitcase Fusion 4 on Mountain Lion, you need to override Apple’s gatekeeper. This is a simple process. See these instructions for details.
- If you are upgrading from an existing Suitcase Fusion 4 install, before you do so, please follow these instructions. These instructions also include details about how to fix any issues if you upgraded before following the instructions.


I downloaded the trial of the suitcase 4 and install it on mountain lion and no way to make it work. I get the following error:
Suitcase Fusion has detected an incompatible version of FMCore. Please can you help me. Thanks
