Hi All,
After a clean install of Keyshot 5.2 on a new MacPro today I was unable to launch Keyshot.
It appears to be a permissions issue.
Navigate to: MacintoshHD > Library > Application Support > Keyshot5.
Select "Get Info"
Manually change the permissions for the folder (and all contents) to "Read and Write" from "Read"
This has been addressed. Please download the installer for KeyShot on Mac again, and run it. This will fix the permission issues.
Sorry for the inconvenience.
