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!
Hi, just wondering is there any further developemnt on this?
I am still having this issue a lot, with many plugins. RMX, Noodler, SuperTool etc. It does not matter which plugin. OS always sends same reponse.
It should only reject plugins that you instal manually. Try to use the Plugin Manager as much as possible. You might need to manually remove the old version.
And RMX should be updated already.
Hi! Sorry I don’t know if you can help me. I have the last version of Catalina and Glyphs. I’m trying to install and use the @Tosche plugin, Pixel Pen Tool (GitHub - Tosche/PixelPenTool: A tool plugin for Glyphs for easier pixel font design.) but I can’t use it. I’ve tried install it by Plugin Manager (restarting after install) and manually following the Tim instructions but the tool doesn’t appear on my tool bar . Can you help me please?
Hi Tosche! Thank you for your tip! The Macro Panel reported an error about Vanilla module, I’ve installed the Vanilla module and now works perfectly installing your plugin from Plugin Manager. Sorry, I think this a beginner mistake
