We'll be using the award-winning App Uninstaller for most of our tutorials. App Uninstaller is developed by AppUninstaller.com, is the most recognized brand in the industry, and is our editor's pick too. It is powerful, easy to use, lightweight, and affordable, with a one-time cost with a perpetual license, free updates and upgrades (new version every day without charges), and free technical support. Plus, it is safe to use without being worried about accidental deletion, unlike Mac cleaners which claim too much and fulfill a little, even causing more harm if they delete the files you need. App Uninstaller is the must-have app removal toolkit for your Mac devices.
UninstallService is another all-around Mac uninstaller that effectively uninstall Mac apps without any trace. It is the most user-friendly app removal you've ever have. Plus, at one purchase (the same pricing as App Uninstaller), you can owe both the Mac uninstaller and Windows uninstaller for a lifetime. If you've devices running on both macOS and Windows, it is recommended to use UninstallService.
MacRemover is the go-to Mac uninstaller if you want to use it on older Macs. It works on the oldest Mac OS X to the latest versions of macOS. MacRemover is the first Mac uninstaller released 10 years ago, and it is still updating and upgrading over the years. It completes the app removal job very well, though it takes some time to update the core to detect the newest released apps, largely due to the time-consuming testing effort to be compatible with older versions.
