How to Safely Remove Language Files on a Mac

When you buy a new MacBook you can instantly start using it in your native language. Since Apple devices are sold all around the world, macOS provides a set of localisation files by default for the user’s comfort. This helps to avoid searching the web to download essential language data.


However, the longer you use your Apple device and the more programs you install, the less free space you have. In this case, removing Mac language files and app leftovers can help you free up some storage.


Before we start


Useless localizations can eat up the precious space needed for your favourite games or your family photos. The easiest way to get rid of them all in one go is to find the perfect app.

What are language files

Localization files are responsible for the language of any app’s interface. For example, in games, it will be anything from item descriptions to dialogues.


Every application that you have on your device utilises pre-installed language files. This is very convenient when you first start using the computer. In time, however, most users find themselves using only a few selected languages. The rest of the 150 language files just take up space on the hard drive.

Where are localization files stored?

Language data is stored locally for each application. To see the list of languages, you need to gain access to the “Resources” folder of that particular app. Each file ends with “.lproj” as the file format.

How to delete language files on a Mac (the manual way)

Removing language files on Mac doesn’t impact your computer’s functioning, but it will help you get some memory space back. You can delete files manually or automate the process with cleaning software.


To delete language files manually, you will need to separately erase each language pack for every third party application on your Mac.


To remove the files manually:

1. In the Applications folder, right-click on the app’s icon and select “Show Package Contents” from the drop-down menu

2. In the list of folders that appears, go to the “Resources” folder;

3. Find any subfolders that end with .lproj

4. Each language file contains shortened names of the languages with the .lproj extension, e.g. en.lproj or pl.lproj;

5. Select all the languages that you do not need and drag them to the Trash bin in the dock. Clear the Trash after.


Depending on the number of third-party apps you have on your laptop, this process can take more time—it gets quite exhausting at times.

Is there a way to remove languages on Mac faster?


MacKeeper can significantly speed up this daunting process. The utility will scan your third-party apps and locate the ones that use language packs. It will then suggest clearing them out. Your location and preferred languages will be taken into account, so the necessary files remain.


How to initiate cleanup with MacKeeper:

1. Open MacKeeper and go to Find & Fix section in the sidebar on the left

2. Click Start Full Scan

5. Back in Safe Cleanup, consider if you also want to delete other junk files such as logs, caches, trash, and mail attachments. If so, check the respective categories

6. Click on Clean Junk Files to get rid of unused languages and other chosen files


Bear in mind that after you’ve deleted the files, you will be unable to use the application in any language other than the ones utilised by your system. If you ever need to use another language in an app, you will have to reinstall it to renew the default language packs. If you cleared the .lproj files for Apple’s own default applications, you will have to reinstall macOS to get the rest of the languages back.


The more third-party apps you have, the more memory space will be freed after the cleanup. You can check what other files are taking up space on your Mac to free up additional space. The first place we recommend to check is Other on Mac storage.  


And if you want to always keep your Mac free from useless files and apps, try MacKeeper. It helps you quickly deal with junk files, needless programs, and duplicates in seconds so that you always have enough storage on your Mac.
