After updating to Mac High Sierra 10.13.1 (17B48), no changes to the Database (FileMaker Pro 12) can be made. When you click "OK" to edit, the database crashes... Any suggestions?
FM 12 is not compatible with High Sierra:
FileMaker platform compatibility with macOS High Sierra
This really is not going to get any better in the future: you can't expect to be able to update your OS every year but not the software that runs on the OS. As I've said before: those OS updates only look like they are free, but they are not...
So either roll back the OS or upgrade to a newer FM.
