A Mac cleaner that shows you everything first.
DiskMate's Cleanup page finds the files that pile up on every Mac, adds them up and sorts them into two lists: Safe to clear, for things apps rebuild on their own, and Worth a look, for real files you might still want. You tick what goes, and it moves to the Trash.
Pay once, keep it forever. No subscription, no account.
Example scan. Names and sizes are illustrative.
What Cleanup finds
The contents of ~/Library/Caches and ~/Library/Logs. Apps rebuild what they need, so these are listed under Safe to clear.
node_modules, build folders, Xcode data, Android SDK images and package caches. See the developer cleanup page for the full list.
Files you already deleted still take space until the Trash is emptied. This is the one item that deletes for good, and it's labelled that way.
Installers and images (.dmg, .iso, .pkg, .xip) you've usually already used. Listed under Worth a look.
Video and audio files over 50 MB, and zip, tar, 7z and other archives over 100 MB.
Anything in Downloads you haven't opened or changed in 90 days.
How it works
- 1Scan
Cleanup checks the usual places on its own and adds what it finds in your scan.
- 2Review
Green items are safe to clear. Orange items are real files, so open the list and look before you tick.
- 3Clean
Press Clean. Everything you ticked moves to the Trash, and DiskMate tells you how much space came back.
Open the Trash, select what you want and choose Put Back. It returns to the exact folder it came from. Only emptying the Trash deletes for good, and DiskMate labels that button clearly.
Nothing disappears by surprise
- Nothing is ticked for you. Every item that goes is one you chose.
- Cache folders are emptied, not removed, so apps find them where they expect.
- Everything goes to the Trash first. Only emptying the Trash itself deletes for good, and it says so.
- System folders such as
/Systemare never touched. - You can add any folder from the Space page to Cleanup under Your picks.
Prefer to do it by hand?
You can clear caches yourself: in Finder choose Go → Go to Folder, type ~/Library/Caches, sort by size, quit the app a big folder belongs to and move that folder to the Trash. Repeat for ~/Library/Logs, then check Downloads for old installers.
It works, but it means visiting each folder, switching on folder sizes and remembering which folder belongs to which app.
Questions
Is it safe to clear caches on a Mac?+
Caches in your own ~/Library/Caches folder are safe to clear. Apps rebuild them when needed, so the only cost is that an app may open a little slower the first time. DiskMate moves them to the Trash rather than deleting them, so nothing is lost if an app misbehaves.
What does Safe to clear mean?+
It means apps or developer tools recreate these files on their own: caches, logs, build folders and package caches. Worth a look means real files you might still want, such as disk images, large videos and old downloads.
Will clearing caches sign me out of apps?+
Usually not. Passwords and settings aren't stored in caches. Some apps may re-download things like artwork or offline data the next time you open them.
Does DiskMate clean automatically in the background?+
No. DiskMate only cleans when you press Clean, and only the items you ticked. There are no background cleaners and no scheduled deletions.
Can I undo a cleanup?+
Yes. Everything goes to the Trash, so you can drag anything back until you empty it. The only exception is emptying the Trash itself, which DiskMate labels as permanent.
