Can someone tell me why my Glyph Icons are like the sample I have attached?
The system that the Mac uses to create file icons changed a few years ago. If you recently updated to a more modern macOS version, ensure you have Glyphs 4 or the latest Glyphs 3 installed.
You might need to allow the quicklook extensions in system settings > Search for “Extensions” and scroll down to “Extension by app” …
Solved. Thank you
