Uninstall Maccy on Mac

Maccy keeps your clipboard history (everything you have copied, potentially including passwords or other sensitive text you did not mean to keep) in a single container folder, and earlier Mole builds selected that folder by default like most application data. Preview builds 290 and later list it but leave it unchecked, because it is your own history; tick it only once you are sure you do not need it. Mole's recorded test uninstalled the Homebrew cask maccy; the official direct download from maccy.app installs the same app under the same sandbox container path, and the steps below apply to both, though only the Homebrew removal was directly exercised.

What Maccy keeps out of your history by default

Maccy's own documentation lists copy types it ignores by default: content flagged as transient or concealed by the copying app, and known password managers such as 1Password and KeeWeb. This reduces, but does not eliminate, what can end up in the history: anything copied from an app that does not mark it as sensitive is stored like ordinary clipboard text. Maccy FAQ

Quit Maccy and remove its Accessibility permission

Quit Maccy from its menu bar icon, then move Maccy.app from Applications to the Trash. Maccy's FAQ states that Accessibility permission is required for it to work; removing the app does not revoke that permission automatically. Open System Settings › Privacy & Security › Accessibility, find Maccy in the list, and remove it with the minus (−) button.

Where Maccy keeps its data

Maccy is sandboxed, so everything lives inside one Container folder named after its bundle id.

Check the result

Run these read-only commands in Terminal:

pgrep -il maccy
ls -d ~/Library/Containers/org.p0deje.Maccy

No output from pgrep means Maccy has quit. ls printing the path means the container, and your clipboard history with it, is still on this Mac; that is expected if you chose to keep it. "No such file or directory" means the local history is gone.

If you installed it with Homebrew

brew uninstall --cask --zap maccy runs the zap list regardless of what you tick, and Mole builds up to Preview 289 removed a Homebrew-installed Maccy that way; later Preview builds leave out --zap for Maccy. The zap list covers the same container, Application Scripts path and preferences file as above, plus the login item. Back up the container first if you want your history for a reinstall, or run the command below to keep everything except the app: Homebrew Maccy cask

brew uninstall --cask maccy

What Mole lists

This describes Mole 1.15 (currently in Preview):

• ~/Library/Containers/org.p0deje.Maccy is listed but not selected in Preview builds 290 and later, because it holds your clipboard history; earlier builds selected it by default like any sandbox container.
• ~/Library/Application Scripts/org.p0deje.Maccy and ~/Library/Preferences/org.p0deje.Maccy.plist are also selected by default.
• The login item shows in Mole's Startup list only while Maccy is installed and is an informational row you confirm rather than toggle from Mole.

What this test covered

Maccy was installed from the Homebrew cask maccy and uninstalled through Mole on September 17, 2026; the cask's zap step took the container, preferences and Application Scripts paths ahead of Mole's own review, with no group container involved. The official direct download was not separately uninstalled in this test; its data path above comes from the sandbox container name Maccy itself declares. No clipboard history containing sensitive text was tested, and the accuracy of Maccy's own sensitive-copy filtering was not independently verified.
