How to uninstall DaisyDisk on Mac

DaisyDisk shows what is using your disk space and can delete files straight from its map. That delete is destructive on its own and separate from removing the app, so back up or move anything you are unsure about before you use it. The steps below cover the official Mac download and the Homebrew cask daisydisk.

Quit DaisyDisk and remove the app

Quit DaisyDisk from its menu, then move DaisyDisk from Applications to the Trash. If you ever used Scan as Administrator, DaisyDisk also installed a helper service, and removing the app does not remove it; the table below says where it lives.

Where DaisyDisk keeps its data

In Finder, press Shift + Command + G and check each location that exists.

Location	What it holds	What to do
`~/Library/Application Support/DaisyDisk`	App data	Review before removing
`~/Library/Caches/com.daisydiskapp.DaisyDiskStandAlone`	Cache data	Safe to remove
`~/Library/Preferences/com.daisydiskapp.DaisyDiskStandAlone.plist`	Preferences	Keep your license key or purchase email if you plan to reinstall
`/Library/PrivilegedHelperTools/com.daisydiskapp.DaisyDiskStandAlone.AdminHelper` and its entry in `/Library/LaunchDaemons`	The Scan as Administrator helper, as named in DaisyDisk's troubleshooting guide	Remove once DaisyDisk is gone; deleting it needs an administrator password
`/Library/PrivilegedHelperTools/com.daisydiskapp.DaisyDiskAdminHelper`	The helper name the Homebrew cask removes	Check for it too; same advice

Check the result

pgrep -il daisydisk
ls -d ~/Library/Application\ Support/DaisyDisk ~/Library/Caches/com.daisydiskapp.DaisyDiskStandAlone
ls /Library/PrivilegedHelperTools /Library/LaunchDaemons | grep -i daisydisk

No output from pgrep means DaisyDisk is not running.
ls -d printing "No such file or directory" for a path means that folder is gone; a printed path means it is still there.
No output from the last line means no DaisyDisk helper file is left; a name starting with com.daisydiskapp means the helper or its launch daemon entry is still installed.

If you installed it with Homebrew

Mole skips --zap when its list reaches unchecked or shared data, or cannot fully be checked, and still cleans the leftovers you selected.

The daisydisk cask's zap list trashes ~/Library/Application Support/DaisyDisk, ~/Library/Caches/com.daisydiskapp.DaisyDiskStandAlone and the preferences file above. With the default selection the Application Support folder stays unticked, so Mole removes DaisyDisk without --zap; tick it and Mole can include it.

Separately from zap, brew uninstall --cask daisydisk always unloads and deletes /Library/PrivilegedHelperTools/com.daisydiskapp.DaisyDiskAdminHelper, with or without --zap. DaisyDisk's own guide names its helper com.daisydiskapp.DaisyDiskStandAlone.AdminHelper, which the cask does not mention, so run the check above after a Homebrew removal too.

brew uninstall --cask daisydisk

What Mole lists

~/Library/Caches/com.daisydiskapp.DaisyDiskStandAlone and ~/Library/Preferences/com.daisydiskapp.DaisyDiskStandAlone.plist are selected by default.
~/Library/Application Support/DaisyDisk is listed but not selected by default, because the folder is named after the app rather than its identifier.
The Scan as Administrator helper under /Library/PrivilegedHelperTools and its launch daemon entry, named after DaisyDisk's own identifier, are listed but not selected by default. Tick them and Mole asks for your administrator password and moves them to the Trash with the app.

What this test covered

DaisyDisk 4.34.2 was installed from the official Mac zip and uninstalled on September 20, 2026, with the official Mole 1.15.0 build 282. The whole review list was ticked, and the app, its cache, its preferences and its Application Support folder were trashed. DaisyDisk was never used to scan a disk and Scan as Administrator was never used, so no helper existed and its removal was not observed. DaisyDisk · Choosing a Mac Disk Analyzer Beyond DaisyDisk
