Verify the download

Every release lists a SHA256SUMS file next to the DMG on the release page. In Terminal, in the folder with both files:

shasum -a 256 -c SHA256SUMS --ignore-missing

You should see AntiChat-<version>.dmg: OK. The app is signed with a Developer ID and notarised by Apple, so macOS checks it too.

Updates and removal

AntiChat checks for updates once a day, downloads them in the background and installs on restart. Your chats and models are never touched. See the changelog.

To remove everything, choose AntiChat › Uninstall AntiChat…, or follow the uninstall guide.
