Mac - Application Crashes on startup - Access Denied

There have been some changes to the permissions on folders used CC and CS6 that are leading to problems using ACR Preset Manager for some Mac user.  On opening a message shows saying 'Access Denied' and then the program closes. 

This can fixed by opening a terminal session and entering the two commands:

  • sudo chmod a+rw "/Library/Application Support/Adobe/Bridge CC Extensions"
  • sudo chmod a+rw "/Library/Application Support/Adobe/Bridge CS6 Extensions"
