How to Deleted or Remove Unused Language Files on Mac

Posted by on .

Foreign language files can take up a lot of space on your Mac. If you're not bilingual or multilingual, then you should consider cleaning them up and freeing up more space from them. There are a couple of ways to do this, but there are a few things to keep in mind.

If you're using a special tool for the purpose on a Mac running anything higher than 10.10 Yosemite, then you will need to disable SIP, or System Integrity Protection. Also referred to as "rootless", SIP is a feature that prevents accidental or deliberate modifications to certain local system files. To avoid disabling SIP, you can use Terminal to execute directly on the command line to remove unused language files. We'll show you how it's done.

Part 1. Using Terminal App to Remove Unused Language Files from Mac

Terminal is Mac's command line interface where you can directly execute different types of processes and tasks. It's a much easier way to remove language files if you know the right command, but tread softly if you're not familiar with command line work. Just follow the process exactly as described below:

Terminal

Step 1. In your applications folder, click on Utilities -> Terminal.

Step 2. Input the following command:
sudo find / \( -name *.lproj -and \! \( -name English.lproj -or -name en.lproj -or -name en_AU.lproj -or -name en_CA.lproj -or -name en_GB.lproj \) \) -exec rm -rf {} \;

If you want to delete foreign language files, you can add -name en_AU.lproj -or within the \(\) command and replace en_AU.lproj with the language file to be removed. It depends on what language files are stored in your system, so if you have several of them, it's going to take a while.

Remember, if you don't know what any of that means, don't try and type it out - just copy it and paste it into Terminal and hit Enter. You also need to ensure that you take a full backup of your system before you try executing this command. If certain parts of your applications are code-signed or non-standard, you may break something and need to restore your computer to a previous state.

If you're not confident that you can execute the process properly, then the recommended method is to use a tool specifically designed for the purpose, which is what we'll talk about next.
