Mac Mechanic is a questionable system optimization tool designed for Mac users

Mac Mechanic is a potentially unwanted program[1] that is advertised as a system optimizing tool for Mac OS X. The business model of such applications is relatively simple: several thousand users install it via software bundling and a full system scan is automatically performed. Victims are then caught in the panic moment when their screen starts flashing several warnings, as hundred of issues are detected by Mac Mechanic. Users are then prompted to buy its licensed version in order to fix the alleged system errors. However, this is merely a scam and there is nothing wrong with the device. Additionally, users complained[2] about unending amount of pop-up ads appearing out of no were and immensely reduce web browsing experience.

| Distribution | Freeware and shareware |
| Symptomps | Regular system scans, pop-ups reporting system's condition, slowdowns |
| OS affected | Mac |

Just like many other similar tools (Advanced Mac Cleaner, Mac Tweaker, etc.) Mac Mechanic promises users that it can fix, clean, and improve the performance of the device. Developers also promise that users can enhance their Mac performance by using such tools as System Cleaner, App Manager, Duplicate Remover, and similar functions. However, Mac Mechanic is merely an adware application that is also actively trying to scam users and providing no actual benefit.
Mac Mechanic has an official website and can be either downloaded or purchased directly. However, to maximize the number of its users, the developers monetize freeware developers for the chance to spread it alongside popular free apps. Additionally, Mac Mechanic virus can also be downloaded and installed when redirected from dubious advertisement banners and pop-ups.
Free apps contain a free trial version of the Mac Mechanic, which once installed loads a fake scanner and initiates a long lasting system scanning. Not only it diminished system's performance, but also generates predetermined scan results, which reports a multitude of Mac problems regarding cache libraries, the excessive amount of junk or even existence of malware.

However, the scan results of the Mac Mechanic are bogus. The tool contains a pre-installed list of scan results,[3] meaning that most of the issues reported are either non-existent or random Mac system's file names.
No, Mac Mechanic is not going to speed up your Mac or otherwise influence its performance positively. In contrary, keeping this tool on your system can result in the following side-effects:
- You can continuously experience irritating system's scans;
- Mac Mechanic virus may generate pop-ups urging to scan the system or reporting serious system's violations;
- Your Mac may get sluggish, especially during Mac Mechanic scans;
- It may download and install other PUPs to the system;
- You may be tricked to pay 39,95 €/$ for a useless license key.
- Random system's files indicated as problematic and, therefore, removed can cause even more serious performance problems.
Users also complained that one of the most irritating traits of Mac Mechanic is that it creates an incredible amount of advertisement, which plagues Google Chrome, Mozilla Firefox or Safari browsers. According to victims, Mac Mechanic also initiated ads when browsers were not in operation at all. All the attempts to remove Mac Mechanic were also in fain, as ads merely returned after deleting its original folder. Nevertheless, please read on to find out how to delete Mac Mechanic ads.
Even though Mac Mechanic app does not feature malicious traits, it's a misleading software that deceives its users by empty and leads inexperienced PC users to money loss. Our partners from senzavirus.it[4] warn that removal of random system files or supposed duplicate files using this misleading app can cause serious outcomes.
The only way to stop this tool from displaying unrealistic and exaggerated scan results is to initiate a complete Mac Mechanic removal from Mac. Since it's considered to be a legitimate Mac assistant, it should have an automatic uninstaller. Therefore, you can try to remove Mac Mechanic virus in a primitive way, i.e., drag and drop it to the Trash bin and then eliminate related files from the libraries.
If, however, you cannot do that because uninstaller is not provided or because the tool keeps reinstalling itself, you should scan the system with a reputable security tool, such as FortectIntego or SpyHunterCombo Cleaner to eliminate Mac Mechanic malware along with its components.
