Getting rejected plug-ins to work with Glyphs on macOS Catalina

I had a few customers reporting that RMX was rejected by macOS after upgrading to Catalina. Strangely, I did not manage to not get RMX to work with Glyphs on Catalina (even though I installed a fresh Catalina on an external hard drive to make sure no “accepted” flags are set for the binary).

Anyway, after playing around with how to get other rejected plug-ins to work, I think I found the right recipe (and this was confirmed to work with RMX as well):

  • When the system complains: do not move the plug-in file to the bin (i.e. klick Cancel)

  • In System Settings > Security and Privacy > General: klick Open Anyway (Make sure this refers to the plug-in. There may be something else in the pipeline.)

  • In the “Install Plugin” dialog: klick Install

  • In the Dialog “… Do you want to override it?”: klick Cancel (this is really important!)

  • Restart Glyphs

  • In the dialog “… Are you sure you want to open it?”: klick Open

  • You may have to restart Glyphs (not sure about this but it does not hurt)

This work-around should work for all rejected plug-ins.

My Apple developer enrollment has been underway for a week – hopefully I can provide you with a proper notarized version of RMX soon.

Please let us all know if you have further insights to share!
