How to speed up a slow Mac
A Mac slows down for a few predictable reasons: memory pressure from too many idle apps, a startup disk that's nearly full, bloated caches, and stale system state. You can fix all of them — and you don't need Terminal.
Free up memory
When your RAM fills up, macOS starts swapping to disk and everything feels sluggish. CleanerMac's Tune-Up runs purge to free inactive memory with one tap — no command line.
Clear the clutter that slows I/O
A near-full disk and gigabytes of caches make reads and writes slower. One-click Quick Clean and Disk X-Ray get that space back.
Refresh stale system state
Flush the DNS cache to fix slow or broken lookups, restart Finder and the Dock to clear glitches, and reset Quick Look — all as simple buttons in the Tune-Up tab.
Keep it fast automatically
Turn on the Quiet Scheduler and CleanerMac maintains your Mac in the background, nudging you with a gentle notification instead of a nag screen.
Make your Mac feel new again
One-tap tune-ups, no Terminal required.
