MacKeeper by Kromtech is one of the most wide-spread and controversial optimisation and security applications for Mac OS. Currently it is considered legitimate and practicable program for performing Mac OS maintenance. However, due to questionable methods of distribution and obsessive behaviour when installed on Mac machines, it is determined by some reputable antivirus products as potentially unwanted application (PUA) or rogue program. For example, BitDefender Antivirus for Mac and Malwarebytes Anti-Malware for Mac detect and offer to remove MacKeeper on our test MacBook Pro. After installing MacKeeper starts showing alerts, reminders and warnings, claiming, that your Mac is “severely infected”, “has serious performance issues”, or “needs deep cleanup”. Annoying windows force some users to buy this application. The scale of the problems is exaggerated, MacKeeper is acting as “scareware”.
MacShiny is fake Mac optimization program, that is promoted via phishing landing pages, claiming it will fix MacOS issues. After infiltration, MacShiny performs PC scan and finds nonexistent or inessential issues on Mac computer, presenting these problems like “critical”. Another trick is waiting for you in subscription payment. It is stated that monthly fee is $1.99, however, it goes up to $49.99 from the second months. There are many complains from our readers, that MacShiny slows down Mac perfomance.
Mac Clean Pro is rogue application for Mac OS, promoted as effective system optimization and cleanup utility. Although, it performs a scan and finds some, probably, unnecessary files – it is impossible to verify whether those files will be removed as it demands $49.95 for removal. If user won’t buy the licence, Mac Clean Pro will bombard the desktop with alerts and messages in the right-bottom corner, saying your Mac needs optimization or heavily infected. Such statements are false, as our team tested application on brand new MacBook Pro and Mac Clean Pro still detects numerous perfomance issues. Either found problems are non-existent or hugely exaggerated, which puts Mac Clean Pro in the category of potentially unwanted apps (PUA or PUP).
Mac Mechanic is potentially unwanted program for Mac OS, that looks like legitimate application for system optimization and virus removal. It originates from India. After the test on new MacBook Mac Mechanic finds several “high-risk” problems and demands from 19.95 to 49.95 Euros for solving. However, some of the results are false, which puts the program to the category of rogue software. When users try to uninstall Mac Mechanic by moving it to trash it says “application cannot be deleted”.
Mac Auto Fixer (a clone of rogue Mac Defender) is bogus Mac OS optimization and antivirus utility. It claims to find numerous errors, viruses and other issues on clean machines. After deeper research those problems appear to be non-existent or not essential. Mac Auto Fixer asks 118 Euros for a 2 year license to fix these issues. There are and there will be lots of applications similar to Mac Auto Fixer, but with other name and design.
