Mac Optimizer Uninstall Guide

If you are a Mac user, then you should probably be aware of the fact that Mac computers do not require any additional optimization or security software. This is why most programs that claim to provide such services for Apple computers are more often than not scams. In this article, we will be focusing on one particular such program called Mac Optimizer, which, instead of noticeably improving anything on your computer, can actually make matters worse. This is why it is important to get rid of this software as soon as possible. Here, we will provide you with all the information that you might need in order to deal with the nuisance and clean it off your machine.

What is Mac Optimizer?

On paper, Mac Optimizer is advertised as software that can improve various aspects of your computer, as well as provide you with a number of useful features. While this might not sound all that bad, things are quite different in reality. First of all, as we already said, if you are using Mac, then you don’t really need any form of optimization software. Secondly, if you are currently dealing with Mac Optimizer, then you most likely have only the free version (which is the one we are talking about in this article). You see, there’s a significant difference between the free version and the paid version of a program. In this case, if you have only the free product, the features and functions that it provides are heavily limited. All in all, what you really get is a free program that constantly nags you to buy the full product. This leads us to the third problem of Mac Optimizer – its obstructiveness and intrusiveness. In order to persuade the user to get the full program (and pay for it), Mac Optimizer might resort to displaying pop-ups on the user’s screen (even when the browser is not open), that report a number of viruses on the computer. This is, of course, nothing but a devious ruse used to making the user worried and tricking them into buying the full product, which is said to be able to remove the aforementioned viruses. In reality, it’s more than likely that there’s no actual infection or even if there is, the unwanted software is not actually detecting it.

Can it harm your Mac?

Even though Mac Optimizer might be rather problematic and annoying, it should not be able to cause any actual direct damage to your machine. Even though you might see people referring to it as a virus, there’s certainly a big difference between actual viruses the likes of Trojans and malware and unwanted programs such as Mac Optimizer. That being said, you should still probably be better off without it and removing it is the course of action that we advise you to take.

How to avoid such software in the future

If you are one of those users, who currently has the unwanted software on their PC, it is quite possible that you have installed it without even realizing it. This is because this type of freeware programs are commonly distributed and installed via some rather stealthy methods.

  • You might have landed the nagging application by clicking on some sketchy online advert. This is how many people get their computers filled with all sorts of undesirable software. That is why, from now on, be extremely careful with what sites you visit and what you click on.
  • Oftentimes applications that fall under the PUP (potentially unwanted programs) category are distributed with the help of different forms of spam (e-mails, Facebook/Skype messages and so on). That is why the next time you are about to click on a link that has been sent to you by a stranger or open an e-mail attachment, the contents of which are unknown to you, you should better give it a second thought.
  • The third, and probably most effective PUP distribution method that we will be focusing on, is the so called file-bundling. Basically, a file bundle is when a piece of software is put inside the installer of another program. For example, Mac Optimizer might have been bundled with some other free piece of software (that you actually wanted to install). However, if you have used the Quick installation option and/or if you haven’t paid attention to the setup wizard (and what settings it contains), you have more than likely missed the opportunity to leave the unwanted application out of the installation. Therefore, each time you are about to install something new on your computer, be sure to take a second look at what you are actually installing. If there are any added/bundled programs, look them up and if you determine that they are unwanted, uncheck them before you launch the installation of the program that you actually want on your system.

Mac Optimizer “Virus” Uninstall

Step1

WARNING!
To remove parasite, you may have to meddle with system files and registries. Making a mistake and deleting the wrong thing may damage your system.
Avoid this by using Combo Cleaner - a professional Parasite removal tool.

The first thing you need to do is to Quit Safari (if it is opened). If you have trouble closing it normally, you may need to Force Quit Safari:

You can choose the Apple menu and click on Force Quit.

Alternatively you can simultaneously press (the Command key situated next to the space bar), Option (the key right next to it) and Escape (the key located at the upper left corner of your keyboard).

If you have done it right a dialog box titled Force Quit Applications will open up.

In this new dialog window select Safari, then press the Force Quit button, then confirm with Force Quit again.

Close the dialog box/window.

Step2

This is the most important step. Do not skip it if you want to remove Mac Optimizer successfully!

Start Activity Monitor by opening up Finder, then proceed to activity-monitor

Once there, look at all the processes: if you believe any of them are hijacking your results, or are part of the problem, highlight the process with your mouse, then click the “i” button at the top. This will open up the following box:

chromeinfo

Now click on Sample at the bottom:

chromesample

Do this for all processes you believe are part of the threat, and run any suspicious files in our online virus scanner, then delete the malicious files:

Maximum file size: 128MB.

This scanner is free and will always remain free for our website's users. You can find its full-page version at: https://howtoremove.guide/online-virus-scanner/

Step3

The next step is to safely launch Safari again. Press and hold the Shift key while relaunching Safari. This will prevent Safari’s previously opened pages from loading again. Once Safari is opened up, you can release the Shift key.

On the off chance that you are still having trouble with scripts interrupting the closing of unwanted pages in Safari, you may need to take some additional measures.

First, Force Quit Safari again.

Now if you are using a Wi-Fi connection turn it off by selecting Wi-Fi off in you Mac’s Menu. If you are using a cable internet (Ethernet connection), disconnect the Ethernet cable.

Step4

Re-Launch Safari but don’t forget to press and hold the Shift button while doing it, so no previous pages can be opened up. Now, Click on Preferences in the Safari menu,

Preferences in Safari

and then again on the Extensions tab,

Step5

The threat has likely infected all of your browsers. The instructions below need to be applied for all browsers you are using.

Again select Preferences in the Safari Menu, but this time click on the Privacy tab,
Privacy in Safari

Now click on Remove All Website Data, confirm with Remove Now. Keep in mind that after you do this all stored website data will be deleted. You will need to sign-in again for all websites that require any form of authentication.

Still in the Preferences menu, hit the General tab

General Tab in Safari

Check if your Homepage is the one you have selected, if not change it to whatever you prefer.
