Since you will probably use a single language on Mac, just get rid of other language files and free up more space on your Mac. A language file cleaner software will also help free up this space.

Hi Mac Users, System is taking an incredibly large amount of space. I mistakenly loaded heavy video files to Numbers and the hard disk immediately filled up. Any help accorded will be highly appreciated.
After I checked my computer storage usage and I was surprised to find my “System” is also taking an incredibly huge space – 43GB of the total 120GB on my MacBook Air.
As well known, the Mac operating system usually takes up from 8GB to 13GB. So I don’t think my Mac “System” storage could be that huge, so I searched to find how it defines “System” storage for a Mac, and how to free up that storage.
What is in the Mac “System” Storage?
The “System” on your Mac storage bar stands for that space your macOS operating system used, including the system itself and the caches and cookies it generated while driving on your computer hard drive.
Sometimes, your Mac may mistakenly put other sections into the “System” storage. For instance, my mac made the mistake of failing to exclude the “Music creations” and “iOS files” (iOS backups) from the “System” storage, so that I get a huge “System” on the storage bar.
And after I clicked the Manage.. button on the top left of the bar, it showed the real system storage was taking only 29.3 GB. And there were two new categories named “iOS files” and “Music creations” being separated.
And the sum of the storage size of these three parts (System, Music Creation, and iOS Files) is 43.38GB, equal to the size of the huge System storage I showed before on the storage bar.

- When storage space is needed, files, photos, movies, email attachments, and other files that you seldom use are stored in iCloud automatically.
- Each file stays right where you last saved it, and downloads when you open it.
- Files that you’ve used recently remain on your Mac, along with optimized versions of your photos.
If you haven't yet upgraded to macOS Sierra or later, learn about other ways to free up storage space.

Store in iCloud
Click the Store in iCloud button, then choose from these options:
- Desktop and Documents. Store all files from these two locations in iCloud Drive. When storage space is needed, only the files you recently opened are kept on your Mac, so that you can easily work offline.

Storing files in iCloud uses the storage space in your iCloud storage plan.

Learn more about prices in your region.
Click the Optimize button to save space by automatically removing watched movies and TV shows. When storage space is needed, movies or TV shows that you purchased from Apple and already watched are removed from your Mac. Click the download icon next to a movie or TV show to download it again.
Your Mac will also save space by keeping only recent email attachments on this Mac when storage space is needed. You can manually download any attachments at any time by opening the email or attachment, or saving the attachment to your Mac.
Optimizing storage for movies, TV shows, and email attachments doesn't require iCloud storage space.

How to free up storage space manually
Even without using the Optimized Storage features described in this article, you can take other steps to make more storage space available:
- Music, movies, and other media can use a lot of storage space. Learn how to delete music, movies, and TV shows from your device.
- Delete other files that you no longer need by moving them to the Trash, then emptying the Trash. The Downloads folder is good place to look for files that you might no longer need.
- Move files to an external storage device.
- Compress files.
- Delete unneeded email: In the Mail app, choose Mailbox > Erase Junk Mail. If you no longer need the email in your Trash mailbox, choose Mailbox > Erase Deleted Items.
- The Storage pane of About This Mac is the best way to determine the amount of storage space available on your Mac. Disk Utility and other apps might show storage categories such as Not Mounted, VM, Recovery, Other Volumes, Other, Free, or Purgeable. Don't rely on these categories to understand how to free up storage space or how much storage space is available for your data.
- When you duplicate a file on an APFS-formatted volume, that file doesn't use additional storage space on the volume. Deleting a duplicate file frees up only the space required by any data you might have added to the duplicate. If you no longer need any copies of the file, you can recover all of the storage space by deleting both the duplicate and the original file.
- If you're using a pro app and Optimize Mac Storage, learn how to make sure that your projects are always on your Mac and able to access their files.
