This guide shows you exactly how to uninstall Maccy and delete all its leftover files. Quick Answer To completely uninstall Maccy, you need to remove the application itself, its preferences, cache files, and any saved clipboard history. Simply dragging the app to Trash is not enough. Below is the full process that removes Maccy cleanly in under 5 minutes. What Files Does Maccy Create? Maccy stores data in several locations on your Mac. Understanding these locations helps ensure complete removal: Application: /Applications/Maccy.app Preferences: ~/Library/Preferences/com.knollsoft.Maccy.plist Application Support: ~/Library/Application Support/Maccy (contains clipboard history and settings) Caches: ~/Library/Caches/com.knollsoft.Maccy Launch Agent (if enabled): ~/Library/LaunchAgents/com.knollsoft.Maccy.plist Step-by-Step: Complete Uninstall Process Step 1: Quit Maccy Completely Before deleting anything, make sure Maccy is not running. Right-click the Maccy icon in the menu bar and select Quit. If the icon is missing, open Activity Monitor, search for “Maccy”, and force quit any remaining processes. Step 2: Move the App to Trash Open your Applications folder and drag Maccy.app to the Trash. Empty the Trash afterward. Step 3: Remove Preferences and Support Files Open Finder and go to Go → Go to Folder (or press Shift + Cmd + G). Delete the following items if they exist: ~/Library/Preferences/com.knollsoft.Maccy.plist ~/Library/Application Support/Maccy ~/Library/Caches/com.knollsoft.Maccy ~/Library/LaunchAgents/com.knollsoft.Maccy.plist (if you enabled launch at login) Step 4: Remove Accessibility Permissions (Important) Maccy requires Accessibility permissions to work with global hotkeys. To fully clean it up: Go to System Settings → Privacy & Security → Accessibility Find Maccy in the list and remove it (click the minus button) Step 5: Restart Your Mac After removing all files, restart your Mac. This ensures any cached processes or permissions are fully cleared. When You Might Want to Keep Maccy Instead Before completely uninstalling, consider whether you actually need to remove it. Many users uninstall Maccy during troubleshooting and later reinstall it because they miss the speed and features. If you’re uninstalling due to performance issues or hotkey problems, try the troubleshooting steps first — most issues are fixable without removing the app. Final Notes Following the steps above will completely remove Maccy and all its data from your Mac. If you’re uninstalling because of a specific issue (hotkey not working, high resource usage, etc.), feel free to reach out with details — many problems have simple fixes that don’t require removing the app. If you decide to reinstall later, you can download the latest version from the official site: best open source mac clipboard manager. how to completely uninstall maccy maccy remove all files uninstall maccy macos maccy clean uninstall guide maccy troubleshooting uninstall best open source mac clipboard manager
