Pretty cool. macOS's Font Book says "Do not use these font files" and then doubles down with, "Serious problems were found with these fonts and may cause system problems or even crashes if installed," and if you still insist on continuing it will copy the file into ~/Library/Fonts but it cannot be used.
- saagarjha 8y agomacOS does this for SF Mono as well and I’ve been successfully using it for years, so I don’t put much credit in that warning.
- mrmondo 8y agoI suspect there is something wrong with the font then, perhaps have a look at the console (app) to see if there are any logs related to the warning and log a bug with the fonts creator? For reference IBM Plex (Mono) fonts that I’ve been using since release do not have warnings and work perfectly, however when I re-encoded them to add ligatures it turned out there were errors with the fonts, macOS warned me and I ignored the warnings, then I noticed higher than expected CPU usage from apps where I had enabled the modified fonts incorrectly.
- mattigames 8y agoI think your engineering must be pretty bad if a font can cause a crash and system problems.
