Thanks for downloading Plumby.

Your download should start automatically. If it doesn’t, download it manually.

While it downloads, here’s what to do next.

Get it running

1Open the disk image and drag Plumby into your Applications folder.
2Right-click the app and choose Open the first time.
3Plumby opens its window, and puts a mark in the menu bar. Both are yours to keep or turn off.

Short, practical reads on memory pressure, System Data, and the disk space macOS hides.

Buy it like a tool, not a service: $19/yr or $59 once. The app stays yours even if you stop.

An honest look at where Plumby differs from CleanMyMac and DaisyDisk, and where it doesn’t.

What’s new in v1.14.2

Cleanup no longer looks like it has frozen. The bar used to count places rather than time. Twenty-eight of the thirty places Plumby checks are done within about three seconds, and the last two take over a minute — so the bar shot to nearly full within moments of starting and then sat perfectly still through the part that actually takes the time. It now measures how long is left, starting from empty.
The bar no longer says it is finished before it is. If a place took longer than it usually does, the reading could sit on 100% while Plumby was still working. Full now means finished.
The amount found keeps rising while Plumby works. It used to jump only when a whole place was done, so it could stand still for a minute on a large one.

You can see where Plumby is looking. The folder it is reading, the file it is on, how many files it has read, and roughly how much longer it will take.
A new picture while it looks — the kinds of file Plumby is finding come up out of your disk and circle it.
