About two minutes. You only do this once — updates install themselves afterwards.

-
Download the disk image
Use the download button above. You get MyMouse-latest.dmg.
-
Drag MyMouse to Applications
Open MyMouse-latest.dmg from your Downloads folder, then drag the MyMouse icon onto the Applications folder.
-
Allow MyMouse to open
Open Terminal (press ⌘ Space, type Terminal, press Return), paste this command, and press Return:
xattr -dr com.apple.quarantine /Applications/MyMouse.appWhat it does: macOS marks every app downloaded from the internet as "quarantined" and asks before its first launch. This command removes that mark from MyMouse only. It doesn't change any other app or security setting, needs no password, and downloads nothing.
⚠︎ Only paste Terminal commands from sources you trust, and know what they do first.
Or, without Terminal:
Open MyMouse from Applications and click Done when macOS says it can't verify the developer. Then open System Settings › Privacy & Security, scroll down, and click Open Anyway next to MyMouse.
-
Open MyMouse and give it two permissions
Open MyMouse from Applications. In the Permissions window, click Open System Settings next to Accessibility and turn MyMouse on, then do the same next to Input Monitoring. Click Restart MyMouse — tap to click works straight away.
Why does macOS warn about MyMouse?
Apple only skips the warning for apps notarized through its paid developer programme. MyMouse isn't notarized yet. Updates are signed and verified by MyMouse itself, so this warning appears only on the first install.
If double-tap zooms the screen
macOS's Smart Zoom uses the same gesture as MyMouse's double-tap. Turn off Smart zoom in System Settings › Mouse, or rebind Double Tap in MyMouse's Settings.
Updates
MyMouse checks for updates once a day and installs them for you. You won't need to repeat these steps.
