Get Rid of Unused Languages and Architecture-Specific Files on Mac

Updated on January 25, 2018

Mac OS X has many languages, and I bet you don’t need most of them. You might want to have Spanish, Chinese, French, Portuguese, or any other widespread language. However, what’s the reason for keeping Welsh, Yiddish, or invented languages like Klingon or Esperanto or dead languages like Sanskrit or Latin? You probably won’t need these languages in the future and can sweep them off to free some space for more important files. Besides, if you need some more extra space, you can also remove architecture-specific files from the so-called universal apps. And in this post, we’ll show you how to do both. Let’s start!

Download and Install Monolingual App

To get started, you need to install Monolingual – a small app that can remove all unneeded languages and PPC-specific files from Universal apps. To do it:

  • Download Monolingual and click on the downloaded file
  • In the appearing window, drag Monolingual icon to the Application Folder

  • Wait until it’s copied to Applications folder

Now, the app is installed and you can move to the next stage.

Remove Unneeded Languages from Your Mac

To remove unused languages, do the following:

  • Launch Monolingual from the Launchpad by clicking on the app icon or go to Finder->Applications folder-> Monolingual. One more way to fire it up is to hit Command + Spacebar, type in Monolingual in Spotlight Search, and click on the app icon.
  • After you’ve launched it, you’ll see a window with the list of all languages included in OS X by default. Uncheck all languages that you want to keep on your Mac.

After you’ve hit it, the program will do the rest. Don’t expect to free up gigabytes of space. The languages do not eat up much. You’ll be able to get about 100 MB. Though it’s not much, getting some space on your SSD for apps and games is always a good idea, especially if you have an old machine and every free byte makes a difference.

Remove Architecture-Specific Files

Aside from language removing, Monolingual can also delete excess files that let apps run on multiple architectures. You probably don’t want to mess up with this stuff, but it’s better to have some background info about what an app is going to do on your Mac. In 2005, Macs switched from PowerPC processor to Intel.

Since that time, many applications have been developed with an ability to run on both Intel and PPC systems. Known as ‘Universal’, such apps were pivotal to a seamless transition from one system to another. However, when Apple completely moved from PPC to Intel in 2013, PPC parts started just taking up space on Intel Macs. So, you can safely remove them. Just do the following:

  • Launch Monolingual
  • Hit Architectures tab in the program’s window
  • Put a checkbox against architectures that you want to remove from your Mac

  • Click on the Remove button to start a cleanup

Monolingual will remove Universal applications turning them into Intel-only. The amount of space you can free up with it depends on how many Universal apps you’ve installed. In most cases, removing architectures will free up more space than deleting multiple languages. But please don’t expect to get that much.

Now You Know How to Use Monolingual

With our simple guides, you’ll easily remove unused languages and apps’ architectures. Even though having 300 MB of extra space isn’t much, for older macs this amount may become crucial. So, don’t ignore these tips, especially if your machine is a far cry from a new one.
