I have a client who has installed FMPA 16.0.4 on Mac OS 10.13.3 and every time they launch the application they get this dialog box:
There are no buttons to click to dismiss this or anyone we've found to get beyond it. We have to force quit FileMaker Pro Advanced each time but it returns when we relaunch it. We found a similar report a few years ago here:
but that had no resolution. We've tried all the suggestions in that thread, including creating a new macOS account, deleting all the prefs/files and reinstalling, disk repair permissions etc. We're installing a full version of 16.0.4 and so far haven't been able to get beyond this.
