Compared to Windows, setting up and removing an application in Mac is simply too easy. To install an application, the user downloads the .dmg file and drags it into the application folder. To uninstall, they drag that application from the applications folder into the trash bin. No DLL files, registry keys, .ini or .nfo files to deal with as in the case of Windows. You’ll never ever need a registry cleaner just to speed up your Mac because there’s no registry to start with.
