Mac Health
See what is taking up space on your Mac, and clear it safely.
Mac Health is a Mac app that explains, in plain English, what is filling your storage, memory and battery, and helps you clear what is safe: old caches and logs, large files, unused apps and leftover startup items.
Available soon Requires macOS 14 Sonoma or later, on a Mac with Apple silicon.
Your Mac says storage is full, and “System Data” is huge.
macOS shows a coloured bar and a mysterious “System Data” number, but doesn’t say what is in it. Memory pressure, swap and a Mac that never sleeps are just as hard to read.
Mac Health looks at your Mac and explains what it finds in plain English, says what is safe to do about it, and does it for you when you tick and confirm.

How Mac Health works
- 1
Open the Overview
Six tiles show the state of storage, large files, apps, startup items, memory and battery, each with the one thing to do.
- 2
Read what it found
Each item says what it is, why it matters and whether it is safe to remove, macOS rebuilds it, or it is yours to keep.
- 3
Tick and confirm
Choose what to clear. It goes to Trash and is logged. Nothing is ever ticked for you except safe leftovers.
Features
Storage, explained
A “safe to clean” checklist: app logs, caches of closed apps, Mail attachment copies, Xcode files. Then where the rest of your space goes.
Large files
Lists files of 100 MB or more in your home folder and iCloud Drive, and big installers in Downloads.
App uninstaller
Removes an app together with the support files that belong to it.
Startup items
Shows what starts with your Mac and finds leftovers from apps you have already removed.
Memory
Memory pressure, swap and apps by memory use, with Restart and Quit. Optional menu-bar gauge.
Battery and sleep
Battery level and cycles, what is keeping your Mac awake, and settings to check.
Safe by design
- Everything goes to Trash after you tick and confirm, and is logged.
- Empty the Trash is the only permanent action, and it is never ticked for you.
- Never touches Apple’s apps, macOS’s own caches, Mail’s messages or your settings.
- Runs on your Mac. Nothing is sent to us.
Questions about Mac Health
What is “System Data” on a Mac?
It is where macOS counts things that don’t fit its other labels, such as caches, logs, swap, the sleep image, Time Machine snapshots and iPhone backups. Mac Health splits it into those parts and labels each one: safe to remove, macOS rebuilds this, leave this alone, or your files.
Is it safe to use?
Yes. Mac Health only changes what you tick and confirm, moves it to Trash and logs it. Your own files and apps are never ticked for you, and it never touches Apple’s apps, macOS’s own caches, Mail’s messages or your settings.
Can it uninstall apps completely?
Yes. Uninstall shows the app and the support files that belong to it, so you can remove them together. If an app has its own uninstaller, Mac Health offers that instead.
Why is my Mac slow or out of memory?
The Memory tab shows memory pressure, swap and which apps use the most memory, counting all of an app’s helper processes. You can restart a big app from there, after confirming.
Why doesn’t my Mac sleep?
The Battery tab shows what is keeping your Mac awake right now and which power settings to check. It never changes those settings for you.
Does it need Full Disk Access?
No, but with it Mac Health can measure Mail, iPhone backups and the Trash. The app explains how to turn it on.
