I try to login this morning with google authentication, and the login dialog does not go away. All the rest is standard: Safari comes to the foreground, asks if it can authenticate, I click the OK button. But nothing happens.

I tried

• restarting FileMaker
• restarting Safari
• relogin to Google account
• another browser ( Vivaldi )
• restarting the Mac
• throwing away com.filemaker.client.advanced12.plist

I tried on my old MacBook ( I switched to a new one recently ) and there everything works correctly.

Next thing I will try is to start throwing away caches, but I wonder: did anyone experience this already? How did you solve it? Please do not tell me I have to reinstall my Mac...:-)

I used Onyx to rebuild launchservices and caches. It was probably launchservices that was broken, since Onyx asked me where FileMaker was using the typical AppleScript dialog, it was in the list, and it was running, so the db was probably corrupted somehow.

Problem solved.
