I have installed, uninstalled, restarted, rebooted, checked Preferences... no matter what, this program usually crashes upon opening.  After I report it twice to Apple, it will open, but with no options to create a new file or to open any templates.

 

I would like to be a new user, but I just cannot get the program to work.

You need to download Opusmodus app for your macOS.

You can't use OM for Catalina on macOS Big Sur etc...

 

You can do the following:

 

1. Quit Opusmodus

2. Go to ~/Library/Caches and delete the com.opusmodus.Opusmodus folder.

3. Go to ~/Library/Preferences/ and delete the com.opusmodus.Opusmodus file.

4. Empty trash.

5. Remove any personal files or code from the ~/Opusmodus/Extensions directory if any.

6. Start OM

Thank you!  This appears to have reset the program, and I can reopen it once more.
