I'm using FM Pro 11 on a MacBook Pro OS 10.13.1 (High Sierra)
Many reports state that FM11 and any other unsupported FM version is crashing on High Sierra.
Bottom line: there's no way out. Either roll back your OS or upgrade to a supported version of FM.
As stated before: these seemingly 'free' OS updates are really not free.
And here's the official line:
FileMaker platform compatibility with macOS High Sierra
all versions from 11 up to 13 will crash under 10.13, sooner or later, mostly when a dialog appears, etc
Strange: FM9 and FM10 seem to work (although there are other issues with these version, as under 10.10 and later)
Good: V11 does convert to 16 mostly without any issues, automatically. There might be some problems with old fonts
Bad: Might cost some bucks - but having V11 for quite some years...
