Plugins not working in Glyphs 3.3

Having issues with my installed plugins. Running the Glyphs app on macOS Sequoia 15.3. So far, just trying to use Show Stem Thickness and Fill Background Path. Neither are working after install and restarting both the app and my computer. Please help!

Can you check what is selected at “Preferences > Addons > Python Version”?

Do you have installed the Glyphs Python module from the Plugin Manager?

Are there any error messages in the Macro Window?

Wow thank you for the quick response!
I do not have the Glyphs Python module installed.
There does not appear to be any error messages?
This is what I see when I go into Settings > Addons

In Python version, select the one with Glyphs in parentheses.

Could you explain this a little more, please? I’m not understanding

Click on the drop-down which says “Python version” in your screenshot. Select the python version which has (Glyphs) in its name. Is it not there?

If it’s not there, go to Plugin Manager and install the Python module.

Ahhhh, that was my issue, there was no other dropdown option.
I went to Plugin Manager and typed in “Python Module” and just “Python” but didn’t find anything with that name. Please excuse my ignorance, I’m fairly new to this.

You find python in the Modules section.

I’ve installed Python Module but still no luck with the plugins.

  1. Make sure ‘Python (Glyphs)’ is selected in Glyphs > Settings > Addons > Python Version.
  2. Consider uninstalling and reinstalling the plug-ins you want.
  3. Restart after these steps.

Thank you for your help. I followed your instructions, then uninstalled and reinstalled the plugin “Show Stem Thickness.” I’ve restarted the app. Still not working… I noticed the glyph app actually doesn’t restart after trying to install this plugin, it just quits and I have to open the app again myself. Usually when it prompts me to restart, the app will open again. But not after installing Show Stem Thickness.

Can you run this code in the macro panel and post what shows up in the output?

import objc
print(objc)

Are you sure you have the latest version of the app? Double check in Glyphs > Settings > Updates.

I did check that, yes. Just double checked, says it’s up to date… using version 3.3. Should i just uninstall and reinstall entirely?

Please run the python test.

Just wanted to say thank you. This helped me solve the same problem for me.

What was your problem and how did you fix it?

None of the scripts were working until I installed the Python module, then uninstalled the scripts, then reinstalled the scripts and restarted Glyphs

Here’s what shows up in macro panel. I even tried uninstalling and reinstalling the Glyphs app entirely, nothing works.

That output means you python is correctly installed.
