Install DevSweep in four steps.

DevSweep comes from this website, not the Mac App Store, so macOS asks you to confirm it once. After that it opens like any other app.

Download DevSweep 1.3.0 Use Terminal instead

macOS 14 Sonoma or later · Apple silicon & Intel · Don’t have a key yet? Buy DevSweep

  1. 1

    Drag DevSweep to Applications

    Open the DevSweep.dmg you downloaded. In the window that appears, drag the DevSweep icon onto the Applications folder, then eject the disk.

    Open it, then click Done

    Double-click DevSweep in Applications. macOS says it couldn’t verify the app. Click the grey Done button. The blue Move to Bin button throws the app away.

    “DevSweep” Not Opened

    Apple could not verify “DevSweep” is free of malware that may harm your Mac or compromise your privacy.

    Click Open Anyway

    Open System Settings › Privacy & Security and scroll to Security. Next to the line about DevSweep, click Open Anyway, then confirm with Touch ID or your password. If macOS asks once more, click Open.

    Paste your license key

    DevSweep asks you to activate. Paste the key from the email you got after paying and click Activate. Moving to a new Mac later? Choose Deactivate this Mac on the old one first.

Prefer Terminal? One line.

This downloads DevSweep, puts it in Applications and opens it, without the warning above. Paste it into Terminal:

curl -fsSL https://newmac.app/install.sh | bash -s devsweep

It needs macOS 14 or later. You still paste your license key when DevSweep opens.

The first time it runs. Nothing to set up.

  • It starts measuringDevSweep reads the sizes of Xcode, simulators, npm, Gradle, Homebrew and other caches. Nothing moves until you say so.
  • No special permissionsNo Accessibility, Screen Recording or Full Disk Access. Searching Documents, Desktop or Downloads for projects is off until you turn it on; macOS then asks once.
  • Docker and HomebrewTheir clean-ups appear when the tools are installed. Docker has to be running for DevSweep to ask what it can reclaim.

If something looks different.

I don’t see Open Anyway.

Open DevSweep once first (step 2), then go back to Privacy & Security. The button appears for about an hour after macOS blocks the app.

I clicked Move to Bin by mistake.

Take DevSweep out of the Trash, or download it again, and drag it back to Applications. Then start again from step 2.

Where is my license key?

In the receipt email from Dodo Payments, sent the moment you paid. Check your spam folder if it isn’t there, or write to [email protected].

How do I update DevSweep?

It updates itself. You can also choose Check for Updates… in the DevSweep menu, or see what’s new.
