i made some adaptions (mainly ligatures) in an existing monospace font and exported it.
When installing, Mac OSX warns with a fatal error called “Überprüfung des Systems”.
When checking the font in FontForge, it says following warning:
“The following table(s) in the font have been ignored by FontForge. Ignoring “DSIG” digital signature table.”
How can I fix that issue in Glyphs?
Do the errors cohere?
Did you make the fonts with Glyphs?
The dsig table it exported to make Windows recognise it as OpenType font, but is empty and should not cause problems. Does the validation show any other info?
Which version of macOS? In some system versions it depends
from where you install the font.
See the related tutorials please:
Update: see this related post/thread:
Do not trust the validation of Font Book, it is very buggy. Most validation errors are triggered by the way the font is installed, e.g. if you double click a font from within the Adobe Fonts folder, Font Book will tell you the font is broken. If you drag the file on the desktop first and install from there, you don’t get the error.
Installting the font file from desktop made the warning disappear. (OSX15)
I made the font changes with glyphs, I do not know where the original file was made in.
No other information in the FontForge validation.
