⚠️ Caution for those of you with ancient fonts ⚠️ Accessing old font files that use a Resource Fork may cause a kernel panic on macOS Tahoe 25.1 &amp; 25.2. Selecting such a file in Finder will immediately reboot your Mac. Be careful of unsaved data! ttf/otf files are fine — Resource Fork files were primarily used on classic Mac OS (pre OSX)

If these fonts are imported into Typeface app, or any other font manager, I’d recommend to (temporarily) move the old fonts into a separate folder that is not accessed by the manager. To do that choose View › as List in Finder, which seems to prevent the kernel panic when selecting the font files. Or use Terminal to move the affected files. It appears that the kernel panic may be related to Resource Forks on external disks and accessing files located on the internal disk may be fine, but more investigation is necessary to confirm.

@Typeface@typo.social thank you for the heads-up!! Is there a way to scan our hard drives to see if we have fonts that contain Resource Forks? For example: I might have ancient fonts spread out in packaged archives from old old projects, and having a tool to locate them would be handy.
