Any question
Some of your fonts may be corrupted, or your macOS font cache may be corrupted
This may happen more frequently if you have installed too many fonts, such as over 1000 fonts
Please move unused fonts out of the Fonts folder and only keep frequently used fonts, trying to keep them under 500
Then, restart your Mac while holding down the Shift key until "Safe Mode" appears on the screen
This will allow your Mac to delete and rebuild the cache, including the font cache
After the login interface appears, log in to your user account, and then restart your Mac again, without holding down the Shift key
Then, try using MathMagic again
If this step does not solve the problem, search for and use a third-party tool to repair the font cache on Google or the App Store
Additionally, try obtaining a brand new copy of the font (in OpenType or TrueType format) from the font supplier and reinstalling it
Also, check the permission settings of the font file to see if it has at least "Read" permission
If the font is in a subfolder, move the font out of it and install it directly under the Fonts folder
Alternatively, if possible, install the font under the (root directory)/Library/Fonts/ folder, which can reduce permission-related issues
Then, restart your computer and try again
