Monolingual

Monolingual is a program for removing unnecessary language resources from macOS, in order to reclaim several hundred megabytes of disk space. It requires a Mac with Apple silicon and at least macOS 27.

I don't know about you, but I use my computer in only one (human) language — English. And I'm willing to bet that you do too, albeit perhaps not English. So why do you have a bunch of localization files for the operating system filling up your hard drive? Enter Monolingual — a handy utility for reclaiming your space for more useful things… like international mp3 files, email or whatever you like.
