What Optimize does.

Service refreshes

Restarts Spotlight, Notification Center, the keyboard input menu and Universal Clipboard when they hang.

Launch speed

Rebuilds Quick Look previews and file thumbnails, and frees up inactive memory.

System databases

Clears old download quarantine history and notification records, compacts Mail and Messages data, and removes broken recent and sidebar lists.

Network & search

Removes Spotlight settings left by apps you deleted.

System maintenance

Removes broken background services and login items, repairs corrupted preference files, ejects idle disk images and resets home folder permissions.

macOS scripts

Runs macOS's own maintenance scripts and finds broken command-line links.

How it works

Three steps, no surprises.

1
Press Optimize
Disklumo runs each task in turn and shows its progress.
2
Enter your password if asked
Some tasks need administrator rights. macOS asks for your password for that run only.
3
Read the results
Every task and service refresh is listed with its result.

Safe by design

You stay in control.

Your documents, photos and app data aren't touched.
Tasks that need administrator rights ask for your password each run. No helper stays installed.
Every task's result is listed when Optimize finishes.

FAQ

Questions.

Is it safe to run Optimize?

Yes. Optimize runs maintenance that macOS supports, such as rebuilding caches and refreshing services. It doesn't delete your documents or change your settings.

Why does Optimize ask for my password?

A few tasks, like running macOS's maintenance scripts, need administrator rights. macOS asks for your password for that run, and Disklumo leaves nothing running with those rights afterwards.

How often should I run Optimize?

When something feels stuck, like Spotlight not finding files or previews not loading, or every few weeks as routine care.
