I have searched the archives here and have not found an answer to this question.
We have a FileMaker runtime that we distribute and on some occasions users contacts us because they cannot even launch the program, receiving the error: file is not modifiable.
Before El Capitan, I would instruct the users to do two things: First, go to the Applications/Program Folder (our program) and do a GET INFO on it. Scroll down to Sharing and Permissions and make sure all three privileges are set to R&W, and then apply to enclosed items.
Second, I would instruct them to repair disk permissions. Most of the time, these work and the user can then launch the program.
With El Capitan, Apple has removed the 'repair disk permissions' feature, as they say it is no longer needed.
Who am I to argue with Apple?
But how do I fix this issue now?
Any help would be much appreciated.
