My app uses AppleScript extensively. On Mojave I have implemented a nice warning that my app needs access to AppleScript in Security and Privacy. However, it constantly loses this access. I just got a mail from a customer again with this problem.
In the months working with Mojave I only had similar problems with the backup app Arq which lost access to the harddisk at least 3 times. One time it lost access to the keychain from one hour to the next.
But other apps don’t seem to be affected by such problems.
Is it possible that my helper apps could confuse the wonderful Mojave? I have 2 helper apps and one login item. All of them have the same bundle id. When checking other apps with helpers (Arq and Wunderlist) I see different bundle ids between main app and helper app.
