By default, macOS has support for multiple languages. If you do not use these languages, the files required can take up space with no benefit. You can set CCleaner for Mac to remove language files for specific languages during a cleaning process.
To set which language files CCleaner for Mac will keep:
- In the left pane of CCleaner for Mac, click Options, and then click Languages.
- Select the languages you want to keep, or clear the ones you don't want to keep. Your macOS installation default language (typically English) cannot be removed.
Note: These settings only specify which languages to keep or discard. You must also make sure CCleaner for Mac is set to clean unneeded languages, which is a separate setting.
- To set CCleaner for Mac to clean unneeded languages, click Cleaner, and then select the Mac OS X tab.
- Select the Unneeded Languages check box.
The next time you run a cleaning process, files for the non-selected languages will be cleared from the system.
