fetchInstalledExtensions only retrieves system installed FS modules

I am trying to list all the installed FS modules.

fetchInstalledExtensions seems to only list the system installed modules (exfat.appex and msdos.appex), even though System Settings --> General --> Login Items and Extensions --> File System Extension lists my custom one and is turned on.

Is this the expected behavior?

Thanks!

It’s a bug. I saw this before too (FB18398975). I was told it’s fixed in macOS 26 beta 6 (25A5338b), and in my tests this appears to be the case.

This is related to FSKit, I tried tagging it, but it didn't seem to work

Thank you so very much @kthchew, much appreciated!

I have been banging my head against the wall on this for a really long time!
