The linked msdos source code on GitHub has since been rewritten by Apple /again/ [1], so the article is a bit out of date. This happened 3 months ago, and it now plugs into a private framework named FSKit.

I did not immediately see any private entitlements that restrict access to this API, nor is msdos.fs signed with special entitlements on my machine. Chances are this API works for any filesystem by dropping an appex into /Library/Filesystems. Looking forward to this being documented and made public eventually.

Thanks. I was aware of FAT being the first filesystem in userspace (maybe for iOS devices to mount SD cards?) but did not know it was open source or that FSKit existed. Maybe an enterprising hacker could dump the Obj-C header from that framework and start writing a FUSE translation layer.
