Installing a valid temporary license (typical for classes or workshops) may yield the following error message:
Register Glyphs 3
The license expired.
Please obtain a new license.
Glyphs will run in Demo Mode.
…even though the date on the license has not been passed yet.
This is a rare issue, and I am sad to say we have not been able to pin it down yet. Somehow the date comparison fails under certain, rare, circumstances. So far, all I can say is:
- only Macs with Big Sur are affected,
- it always works in a separate user (create a new one in System Preferences > Users),
- at least once, removing system maintenance utilities (antivirus software, ‘cleaners’, monitoring tools) seems to have been related.
