Clear cache and free up storage
LumaSpace downloads wallpaper files to your Mac so they play smoothly. Over time, this can use noticeable storage.
Clear the cache
- Open LumaSpace.
- Go to the Settings tab.
- You'll see how much space LumaSpace is using (e.g., "256 MB").
- Click Clear Cache.

What happens after clearing?
Your wallpapers aren't deleted — they're still available in the app. But the next time you apply one, LumaSpace will need to re-download it (takes a few seconds).
Your uploaded wallpapers (in the Library) are stored separately and aren't affected by clearing the cache.
Tip: LumaSpace has a built-in storage limit of about 500 MB for cached files. It automatically removes old files when space is needed, so you don't have to clear it manually very often.
