Its aggravating persistence, constant pop-ups, and scareware features soon enough make even the most gullible users to doubt this program’s legitimacy and look for answers to why Mac Tweaker acts the way it does and how to remove it.


At first, innocent-looking system optimizer Mac Tweaker seems like a serious tool, which only wants the best for its customers and right after the installation begins scanning all the folders and showing critical errors in them, rushing user to take an action right away and clean up duplicate and junk files, rogue software and etc. However, once the person clicks on ‘Clean Now’ button, the program explains that in order to fix so many issues, you have to get a full version of Mac Tweaker, which apparently is one of an infamous PCVARK companys creations.

What is Mac Tweaker PUP

As you can tell from the introduction, Mac Tweaker is not a trustworthy product, but an unwanted application, which simply pretends to have abilities to detect Mac OS errors. Not only it doesn’t provide any benefit to the users, but it also uses scareware techniques to force its customers to pay the company for the full version, so that the presented issues could be solved. This is a tricky part not to fall for Mac Tweaker’s scam because there are tons of legitimate programs that use this kind of free-scan-paid-removal model. The difference is that reputable software does really detect problems of the system and solve them, while PCVARK’s Mac Tweaker generates random large numbers even on a clean system and then pretends to fix it by simply showing different results. Such a useless program requests for €39.95 for 6 months and the subscription renews automatically after that unless you cancel it.

In some cases, you are allowed to select the Setup Wizard mode, whether it’s Custom/Advanced or Express/Recommended installation where you can check which apps you want to set up and which ones not, but often such questionable program bundles install every content all together with no choice.
