Finder shows you the files you put there. It doesn't show you what the system put there.
macOS's "About This Mac → Storage" gives you a rough breakdown, but it lumps everything together under vague labels like "Other" and "System." CleanMachine drills into every specific category:
Apple's storage analyzer groups many of these categories into a mysterious "Other" bucket that can be 30–80 GB on an older Mac. CleanMachine breaks that down into specific, actionable categories with file counts and exact byte sizes.
Beyond the junk scan, CleanMachine's Space Visualizer renders a DaisyDisk-style interactive sunburst chart of your entire storage. Click any slice to drill down. This is the fastest way to answer "where did 20 GB go?" for non-junk files like large video projects or software downloads.
Scans all junk categories in parallel — caches, logs, language files, browser data, old downloads. Shows total per category before you clean anything.
Interactive sunburst chart of your entire storage. Drill down any folder to find exactly where gigabytes went.
Scans your home directory for files over 50 MB. Sorted by size. Find the space hogs instantly and decide what to keep.
Full MD5 comparison finds byte-for-byte identical files. Often recovers 2–10 GB on first scan. Auto-keeps your newest copy.
Lists all iOS device backups with sizes and dates. Multi-select delete for old backups you don't need — often 20–80 GB recovered.
Tracks historical disk usage and projects when your disk will be full. See your storage trend before it becomes a crisis.
Download CleanMachine and run a free scan. You'll see every category of hidden storage with exact sizes. Only pay $19.99 once to actually clean it up.

It depends on your Mac, but most users recover 5–15 GB on their first clean. Developer Macs often recover 20–50 GB. The scan shows your exact number — for free — before you pay anything.
Yes. App caches are designed to be regenerated — that's the whole point of a cache. Deleting them just means the app rebuilds fresh ones on next use. You might notice apps take a tiny bit longer to load the first time after cleaning, then they're back to normal.
Only if the backup is your only backup. If you use iCloud Backup, deleting old local backups is safe — your phone is already backed up to iCloud. CleanMachine shows the backup date so you can decide which ones are safe to remove.
Apple's "System Data" label covers many things including caches, logs, and temp files. CleanMachine breaks this down into specific deletable categories so you can see and control exactly what gets removed.
