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 64-bit capable Intel-based Mac and at least macOS 10.13 (High Sierra).

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.

Version 1.7.8 is the last version for OS X 10.12 (Sierra). Version 1.7.3 is the last version for OS X 10.11 (El Capitan). Version 1.6.7 is the last version for OS X 10.10 (Yosemite).
