One app for your whole Mac.
Free up storage, see what is using your memory, and find out why your Mac slows down.

Make the invisible visible. A deep scan flags every file taking space. System Data included.
Every app, properly managed. Updates, leftovers, and what opens at login. Not just a size to delete.

Free up memory. The heaviest apps, ranked. Pause the top one and watch the number fall as macOS reclaims what it parked.
Take the controls. Set the fan curve and energy mode yourself.
Monitor what matters. CPU, memory and temperature in the menu bar. The fix sits next to each.
Repair what a restart won’t.
Blank previews. Garbled fonts. The wrong app opening your files. Search that stopped finding things. Pick the repairs, preview each command, then run them. No Terminal.

- Rebuild Launch Services
- Reset font cache

The repair, and what it reported
Every task is a documented macOS repair, not a tune-up we invented. What you see afterwards is what the repair reported.
One password, not six
The tasks that need an administrator are gathered into one prompt, or none once Plumby’s helper is installed. Nothing to copy and paste.
Nothing runs uninvited
Each task has its own switch. The one that needs a restart is off by default, and a tune-up tells you what it did.
See who your Mac is talking to.
Activity Monitor counts the bytes and stops there. Plumby names the destination, and shows what each connection is using right now.
Named, not numbered
Every connection is looked up and nested under the app that opened it: fonts.gstatic.com under Google Chrome, not a page of 142.250.x.x.
Live, per app
Down and up per app, sampled every two seconds from the counters macOS uses. An idle Mac draws a flat line, never a decorative wave.
A day behind every number
A day of totals sits behind each app, so whatever ate your data has a name by the time you look.
Everything else, one menu away.
Small jobs that usually mean a support thread and a trip through System Settings. Each one would be its own app somewhere else.
Unstick things.
Force-quit what’s frozen, flush the DNS cache when a page won’t load, and free the drive that won’t eject.
Apps, removed completely.
Drag-to-Trash leaves the caches, preferences and helpers behind. Plumby lists them by path, then takes them with the app.
Fans & power.
Set fans to Auto, Cool, or Max, flip macOS Energy Mode, and read battery health down to the cycle count.
Meetings & focus.
One tap before you present: desktop icons hidden, mic muted, notifications off, and back the same way.
Startup, trimmed.
Everything that opens itself at login, including the helpers. Unused ones are flagged.
Devices & drives.
Battery levels for every paired Bluetooth device. Eject a stuck drive, and see what was holding it.
How Plumby compares.
The difference is where the number comes from, and what the app can touch without asking you first.

|---|---|---|---|

| Where cleared files go | PlumbyTrash or delete, your choice | CleanMyMacVaries | DaisyDiskThe Trash |
| Pricing | Plumby$39/yr or $89 once | CleanMyMacSubscription | DaisyDiskOne-time |
CleanMyMac and DaisyDisk are good apps, and this stays general on purpose: a spec sheet changes every release. It is just where Plumby differs.
Why Plumby?
Documents, photos and the folders you work in are never candidates. Caches, logs and leftovers are.
Every cleanup is an opt-in checklist: you approve exactly what goes.
An app isn’t “handled” until Plumby checks it exited.
Send what it clears to the Trash (recoverable), or delete it outright, your choice.
Lives in the menu bar. Never in ⌘-Tab, never in your Dock.
One approval at setup. No password prompts after.
Developer ID-signed and notarized by Apple, so macOS checks it before it ever opens.
Refundable either way, no reason needed. Ask and it is done.
No analytics, no telemetry. Your files, processes, and network data stay on the machine.
Every figure is read from the system, never modelled. Nothing is a guess dressed up as a number.
Buy it like a tool, not a service.
Pay yearly, or pay once and get every version we ship. Either way the app is yours, and it keeps working even if you stop.
Free to download.
Install Plumby and see your own numbers: what is filling your disk, what is using your memory, what is inside “System Data”. Buy when you want it cleared.
