There are thousands of applications that would claim they can clean up a Mac device and make it run smoother and faster. Few of them have anything to offer over the native maintenance tools provided by apple. UltimatMacCleaner is not one of them. If you see the PUP.MacOS.UltimateMacCleaner.A detection, you have probably installed a PUP. Like other similar software, UltimatMacCleaner doesn’t have any significant functionality over what the user can do with macOS’s native tools which is one of the reasons it’s classified as a PUP.
UltimatMacCleaner may include various supposedly useful features. Most would-be cleaners of this kind have a startup manager. This component is in no way better than the manager integrated in macOS. The original tool Apple offers as a part of its operating system can be found in System Preferences and it provides the user the necessary control over the startup items. One could say it offers more control because it can disable UltimatMacCleaner on startup, and UltimatMacCleaner cannot.
The fact that cleaners don’t have any useful features alone doesn’t make them malware. In most cases, such applications don’t seriously endanger the security of the machine they run on. However, those applications can be annoying and sometimes even display false warnings to try to push other shady software. For those reasons, a number of the most popular antivirus software suites detect UltimatMacCleaner as a PUP (short for a Potentially Unwanted Program). This designation is very fitting and it is applied to exactly this type of application.
UltimatMacCleaner can come in bundles with other applications. Fortunately, the removal of UltimatMacCleaner isn’t extremely complicated. Most all security solutions will easily uninstall UltimatMacCleaner. Many users will be able to remove it without too much trouble even without the use of other applications. All the user has to do is open Force Quit Applications, find UltimatMacCleaner and force quit. After that the user can follow the usual process of uninstalling an app from a Mac.
