I am trying to submit fonts to MyFonts on Prosper. The native font validator shows error that fonts cannot be Installed on MacOSx/MacOS" and shows message "Your font may have serious errors. Please check your font files." I have uploaded files in ttf format. Tried with otf too. I use Fontlab VI Windows to create fonts.
I cannot understand what could be the problem. Anyone with experience please help. Thanks
The good news is, this is probably something very simple to fix.
Edit: I agree that it is a Very Good Idea to test stuff on both Mac and Windows.
And it's shocking how many designers think they can stick to testing on Apple products.
That said, using a good set of test tools can be incredibly helpful, and reduce the frequency/amount of cross-platform manual testing needed.
Both the Adobe AFDKO CompareFamily and Microsoft Font Validator are good ones to have around. However, to some degree both, but especially Font Validator benefit from having their output interpreted by somebody who is familiar with them. Otherwise it is hard to know how serious some of the warning messages are.
I use MS Font Validator once in a while but the results are pretty noisy and it ends up finding the same glitches anyway. For stubborn, hard to track down issues, MS Font Validator is good to have.
Error reason: "Failed to parse table".
But what the exact table? What interesting – I have different fonts with same features/tables, exported with the same settings. And only one family have this problem. Checked the font on MacOS (Font Book and Adobe applications) and everything works correct, including all the features. Still interesting about details of this issue.
