I have a problem when I want to install the license glyphs, I have followed the method on the web but it doesn’t work. even though I deleted the preferences file but it’s still installed

I’ve followed, but still haven’t removed the license

Or can I use this license for my 2 Mac devices?


You need to restart the Mac to make the deleting of the file permanent.
