TuneupMyMac PUP on Mac

TuneupMyMac is the name of a potentially unwanted application that can find its way on your Mac computer. It exhibits some qualities that can classify TuneupMyMac as a rogue optimization app. Rogue applications generally attempt to scare users into thinking something is wrong with their system and then lure the user into paying for fake fixes or system performance upgrades that are not needed in the first place.

Potentially unwanted applications or PUPs fill a gray area between more dangerous malware such as viruses, Trojans and ransomware and regular, safe applications. A potentially unwanted application will generally worsen the user's experience when using their computer or browsing the Internet or, as is the case with TuneupMyMac, may attempt to persuade the user to buy the application by displaying fake warnings or error messages.

TuneupMyMac is presented as a system optimizer. However, the "scan" it can perform is not real and will display fake warnings and a lot of made-up issues and system-critical potential "fixes". However, in order for the user to access those "fixes" in the application, they will need to pay for its full version. The real issue is, those fixes are not needed in the first place and the PUP uses social engineering tactics to scare the user into paying.

Applications such as TuneupMyMac usually get on your system through bundlers. Bundlers or bundle installers are software packages that contain multiple apps. One of those apps may even be a legitimate application, with a potentially unwanted one piggy-backing inside the bundle installer.

Bundlers are commonly found on free download websites and can contain a variety of PUPs in them. The way the installer is usually set up, choosing the express install option never asks for user consent and quietly installs the PUP along with the main app in the bundler. Once the PUP is installed, depending on what exactly it is, it may change the user's browser settings or display fake messages and perform fake scans of the system.

TuneupMyMac will continually nag the user once installed, displaying messages that the system needs tweaking, cleanup and performance optimization. However, even if the user does pay for the full version of the app, the fixes listed are far from vital for system operation and their importance is strongly exaggerated in the scan screens that TuneupMyMac will display.

To stay clear of similar potentially unwanted apps on your system, always donwload your applications from trusted sources and official websites. If you are using installer packages downloaded from free app websites, always make sure you check out all options and custom install settings, so you can be aware of any potential PUPs that are piggy-backing inside the install package.
