Mac Tweaker Removal Guide

Do you know what Mac Tweaker is?

If you are a Mac owner and find Mac Tweaker on your computer, it is possible that you do not even remember installing this seemingly beneficial optimizer. Our researchers say that this software may affect Mac OS X 10.7 and higher versions. There has been a number of similar system cleaners and optimizers in the past months, including Mac Optimizer, Mac Mechanic, and Mac Space Reviver, which all promise practically the very same thing: a faster, cleaner, and error free system. However, this comes at a price and not even a low one. As we have got used to the usual overpricing of Mac devices and services, this optimizer actually costs 10 dollars more than the usual Windows optimizers. The truth is, there is no real analysis today that would prove these programs beneficial or powerful enough to be worth buying them. In fact, we have classified it as a potentially unwanted program, or PUP. Please read on to find out why we suggest that you should remove Mac Tweaker from your computer.

It is possible, of course, that you found this application after a web search and you actually visited its official website,, and this is how you downloaded and installed it. In all fairness, this website looks completely normal and convincing. This is why inexperienced users may believe that it is actually a good idea to install such a tool since the website says all kinds of positive and amazing things about it. Well, it is called promotion, right? It does not mean it is all true. Still, it is understandable that someone would fall for such a website and PUP. This is exactly why it is important that before you download and install any free or paid program, you run a web search on your target to find out whether it is a useful and reliable one. In this case, you may find articles that recommend that you delete Mac Tweaker as a PUP.

Your situation is much worse, of course, if you cannot recall installing this software intentionally because it would mean that it slithered onto your system without your knowledge. This is why you need to be very cautious when you install free software and even more so when you download it from suspicious file-sharing sites because you can easily install a whole package filled with malicious installers as well as PUPs. You can easily drop such a package when you use shady and unfamiliar torrent sites for downloading software, when you click on unsafe third-party ads on suspicious sites, or when your system is infected with adware. Since there is a chance that your computer is not clean, we advise you to scan it with a proper online malware scanner right after you delete Mac Tweaker from your Mac.

As we have already mentioned, this PUP affects Mac OS X 10.7 and higher versions. In essence, this rogue optimizer is very similar to all the ones we have seen on Windows PCs. As a matter of fact, even Microsoft does not approve of such tools since they are not really effective as promised and they may cause more issues by editing the system. This PUP mainly scans your OS for cache, logs, and unused programs. The results list could be a bit scary if you are an inexperienced user since finding hundreds of alleged issues may seem like something you need to fix immediately. However, you cannot go along with it since first, you have to buy the full version of this software. But paying 39.95 EUR for this questionable program may seem like money down the drain; well, at least, for the trained eye. We believe that for this money, you can buy a proper and reliable malware removal application that could really keep your system safe and clean. This is why we advise you to remove Mac Tweaker.

We have prepared a guide for you to be able to remove Mac Tweaker manually whenever you are ready. But you can also find information about its uninstall guidelines if you visit its official site, where you can download an uninstaller to take care of it all. No matter which way you choose, you need to keep in mind that it is possible that several other threats are also hiding on your Mac. If you wish to keep your operating system secure, it may be time for you to start using a decent anti-malware program.

In non-techie terms:

Mac Tweaker is a Mac optimizer application that our researchers have found to be a rogue program that may not be as beneficial as it claims. Since it does not exhibit malicious traits, we have classified it as a potentially unwanted program. This application can show up on your computer when you intentionally install it, but it seems that it can also appear silently when you install other programs. In the latter case, it is quite likely that you will find other unwanted or even malicious programs on your system. This PUP can scan your computer and come back with hundreds or even over a thousand issues to be fixed. However, you will not fix anything with the free version; you have to buy the full version before you could do anything. The problem is that none of these system cleaners and optimizers really worth a cent since you will not necessarily experience any difference even if you clean your cache, logs, and unused applications from your system. We suggest that you remove Mac Tweaker from your Mac if you want one less useless program on board. If you want to protect your computer against future threats, we advise you to install a reliable anti-malware program.
