“Your disk is almost full.”
You deleted photos and old downloads. Storage still says 40 GB of System Data, and nothing tells you what it is.
Mac Fix KitEarly accessComing soon for Mac
Your Mac is full and slow. Fix both in one app.
One small app that shows what is really inside System Data and which apps make your Mac hot, explains each one, and clears what you choose to the Trash.

Sound familiar?
Two problems every Mac gets. One app.
System Data: 120 GB. Of what?
Caches, iPhone backups, Time Machine snapshots and developer files all hide in one grey bar with no delete button.
The fan spins up for nothing.
Activity Monitor shows 400 rows. One app is burning the CPU, and you cannot tell which one is safe to quit.
$40 a year to clean a disk?
Big cleaner apps want a subscription, and many free fixes mean pasting Terminal commands you do not trust.
What 1.0 does
Storage and speed. Nothing else, done well.
Storage
See inside System Data.
Mac Fix Kit breaks the grey bar into things with names and sizes, measured on your Mac.
- Time Machine local snapshots
- App and browser caches macOS rebuilds
- Xcode DerivedData, simulators, device support
- Old iPhone and iPad backups
- Duplicate files and old installers in Downloads
Speed
Find what makes it hot.
The apps using the most CPU and memory right now, as big cards with a plain-English reason and a Quit button.
- Apps that stay hot for minutes, flagged
- Leftover dev servers and helpers from closed apps
- Memory pressure the way macOS sees it
- Quit asks the app to close, like ⌘Q
- Never touches macOS system processes
How it will work
Three steps. Nothing deleted without you.
- 1
Open Mac Fix Kit
It measures your disk and the apps running right now. Nothing is deleted on the first run.
- 2
Read what is big
Each item says what it is, why it grew and whether macOS will rebuild it.
- 3
Clear what you choose
Everything goes to the Trash first, so you can put it back.

Big cleaner prices are from public reviews in October 2026 and change often. Mac Fix Kit is not on sale yet; the price may change before launch, and early-access members hear first.
Safe by design
It clears files. Carefully.
Trash, not delete
Everything Mac Fix Kit clears goes to the Trash. Nothing is gone until you empty it.
No scare scans
No red alerts, no “14,382 problems found”. Real sizes, real names, your call.
Nothing leaves your Mac
No account and no cloud. The only network call will check your license key.
Signed and notarized
Built in Swift for macOS 14 and later, signed with a Developer ID and notarized by Apple.
Rather do it yourself?
Free guides, tested on a real Mac.
FAQ
Good to know.
When can I get it?
Mac Fix Kit is in development. Leave your email and you get one note when the beta is ready, nothing else.
How much will it cost?
The plan is $19 once for the full app, no subscription, with a free trial first.
Is it a cleaner that scares you with red warnings?
No. It only shows what is on your disk with real sizes, explains each item, and never deletes without asking. Nothing is removed permanently: it goes to the Trash.
Can I do this myself for free?
Yes, and our free guides show the Terminal commands step by step. Mac Fix Kit is for people who would rather see it and click once.
