Inside Disklumo
CleanEvery item shows its size and path. Keep what you want; by default the rest goes to the Trash. Sign-ins, browsing history, chats and local models are kept.
More about Clean →
AppsThree tabs for the apps on your Mac: what to remove, what to update, and what runs when you log in. Every update is checked before it's installed.
More about Apps →
AnalyzeYour whole disk as a map, so the biggest folders stand out at a glance. Results start appearing while the scan is still running. Find any file by name, hidden folders included, and measure external drives too.
More about Analyze →
StatusA health score with the reason behind it, and live cards for every part of your Mac, refreshed every two seconds.
More about Status →
OptimizeRefreshes Input switching, Spotlight, Notification Center and Universal Clipboard, then runs 17 maintenance tasks. Some tasks ask for your Mac password.

New in 1.1Files you have twice, compared byte for byte, not just by name. Disklumo suggests which copy to keep, and one copy of every file always stays.
Backups Finder made of iPhones and iPads you replaced, often tens of gigabytes. Listed by device and date; you pick which ones go.
Installers still sitting in Downloads, and large files you haven't opened in months or years.
Search any file by name as you type. Get Info shows size on disk, space saved by compression and the largest items inside.
How much space you've cleaned up, week by week. Recover files puts back a whole cleanup in one click.
A notice when your Mac is nearly full, and an optional weekly reminder to clean up. Free space is always in the menu bar.
Tools
Keeps the screen awake, so closing the lid still sleeps your Mac. Can keep tasks running too, with the optional helper. Pauses itself when the battery runs low.
Covers the screen and locks the keyboard so you can wipe them. Stops after 1, 2 or 5 minutes, or hold Escape to exit.
Fans on Auto, Cool or Max, and an 80% charge limit on supported Macs. Everything goes back to normal when you quit.
Reduces Wi-Fi lag in games and calls by pausing AirDrop while it's on. Uses the optional helper.
Clears build caches and outdated installs left by Claude Code, Codex, Cursor, Gemini CLI and others. Chats are removed only if you select them.
A read-only report about your Mac and Disklumo. Report a Problem puts it in an email to support, and you see it before you send.
Safe by designNothing is removed until you review it and confirm. Then, by default, it goes to the Trash.
Cleaned items go to the Trash by default, uninstalled apps always do, and "Recover files" puts back one item or a whole cleanup. System Data items are deleted directly, and logs still being written are emptied in place. The confirmation tells you which.
If a file changed or is in use after the scan, Disklumo leaves it alone instead of cleaning it.
Keychains, Mail, Messages, Safari, iCloud and Apple's own apps are off limits.
System Data and Optimize ask for your Mac password for that run only, and the access is removed when the run ends.
No account, no analytics. Disklumo goes online only for your license, its own updates, and app update checks you open.
Disklumo is signed with an Apple Developer ID and notarized by Apple, and every update is signed too.
Everything you copy, one shortcut away. Search it, preview it, paste it again.

Disklumo Clipboard is a small menu-bar app that keeps a history of what you copy, so you can search and paste it again. It comes free with Disklumo: download it from the page you see after checkout. It needs no key or account, and your history stays on your Mac.
No. Disklumo Clipboard is a separate app and works on its own. It runs in your menu bar; press ⌥ Space to open it. Like Disklumo, it needs macOS 14 or later on Apple Silicon.
No. Copies from Passwords, Keychain Access, 1Password, Bitwarden and Dashlane are skipped, and so is anything an app marks as private. You can add more apps to skip in Settings, pause recording, or clear the history at any time.
Macs with Apple Silicon (M1 or newer) running macOS 14 Sonoma or later. Intel Macs aren't supported.
Cleaning System Data and some Optimize tasks need administrator rights. Disklumo asks for them for that run only and removes them when the run ends.
The optional helper is the one exception. Fan & Battery, Wi-Fi Low Latency and Stay Awake (when it keeps tasks awake) use it, and it stays installed so it can restore your fans and charging after a crash. You can uninstall it from Fan & Battery at any time.
It's recommended. Without it, macOS hides the Trash and some protected folders. Disklumo tells you which ones it couldn't read.
No. Scans happen on your Mac. Disklumo only goes online for your license and for updates. See the privacy page.
Yes, within 7 days of purchase. Email support@disklumo.com from the address you bought with, and you get your money back. The license key stops working after the refund.
Yes. One key works on one Mac at a time. Open Key › Deactivate this Mac on the old one, then activate the key on the new Mac.
No. Download it again from updates.disklumo.com/Disklumo.dmg and open it: on the same Mac it's still activated. If it asks for a key (for example after you erased your Mac), paste the key from your purchase email. If it says the key is already in use, email support@disklumo.com and we'll free it.
Email support@disklumo.com. Or choose Help › Report a Problem… in the app: it opens an email in Gmail or your mail app with your Mac details already filled in. You see everything before you send it.
See what's taking up space, keep what matters, and clean the rest with confidence.
