How irritating is this problem? (8 votes, average: 5.00)


This page aims to help you remove Mac Tonic “Virus”. Our removal instructions work for Safari, Chrome, Firefox, as well as every version of MacOS.

Annoying apps like Mac Tonic can be encountered everywhere on the Internet since their creators seek to find more and more ways to distribute them and get them installed onto more computers. If you have Mac Tonic “Virus” on yours, then you have likely started to notice some of the more typical symptoms.

What is Mac Tonic?

Mac Tonic is a potentially rogue program that gets installed without the user’s permission or desire. This usually happens with the use of third party apps (adware and browser hijackers). For instance, your browser might have started to behave in an odd way – random ads might have started popping-up on your screen, your searches might have started to get redirected to unknown pages and also you browser’s appearance and settings might have been altered without your permission. For instance, the starting page, the toolbar and/or the search engine tool of your Safari, Chrome or Firefox (or any other) browser might have gotten replaced by some new and unknown/undesirable ones. Other similar symptoms might also be noticed but those were the most common ones when talking about Mac Tonic. In fact, the aforementioned activities that this app might conduct are very typical for a software category known as browser hijackers which is why we believe that Mac Tonic belongs to this group of apps, programs and software components. The browser hijacker category is notorious for its intrusiveness and ability to make changes to the user’s browsers and obstruct their regular online activities with constant ads generation and redirects to random sponsored pages. Due to their unpleasant and invasive behavior, most pieces of software that fall into this category are regarded as unwanted and pretty much anyone who gets a hijacker installed on their computer wants to have the pesky app removed as soon as possible. Our task in the next lines will be to acquaint our readers with the specific traits and characteristics of browser hijackers like Mac Tonic and also to help any of you who might presently have this undesirable app on their machine have it removed and uninstalled. If you are on this page because you are seeking a way to eliminate the browser hijacker from your computer and browser, know that the instructions that will help you to do so are located in the removal guide that’s down below this page.

Remove Mac Tonic


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.



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:


Now click on Sample at the bottom:


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:

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.


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,

and then again on the Extensions tab,

However, remember it is also important that you finish reading the remainder of this article as it’s highly important to be well-informed with regards to the nature of those apps. Another thing to note here is that inside the guide there’s a recommended tool for removing unwanted apps like this one which you could also use against Mac Tonic if you think that you won’t be able to complete all the steps from the guide or if for some reason they do not fully eliminate the intrusive software.

How dangerous are browser hijackers?

A hijacker is certainly not as harmful as Ransomware, Spyware, Trojan Horses or some other similar nasty malware threats. Browser hijackers are advertising tools and their purpose is normally different from the purpose of actual PC viruses. However, if you have a hijacker on your machine, you should still probably remove it and in the meanwhile be careful around its ads, banners, pop-ups and page redirects as they might sometimes not be as reliable or as safe as they may seem. Even if you can put up with and ignore the constant stream of ads and the frequent redirects to random webpages that you aren’t interested in, you still need to ensure that the unwanted app is removed for the sake of your computer’s safety. Though not a real virus, a software piece like Mac Tonic might potentially display unreliable and even unsafe advertising materials on your screen. This means that you could easily land some nasty virus infection like a Ransomware or a Trojan if you have the misfortune of interacting with some hazardous advert.

How could a hijacker reach your PC

A lot of unwanted apps get to user’s PCs by getting distributed via spam messages, unreliable and pirated downloads, shady online offers and ads generated by sketchy sites and so on. However, with hijackers, there’s one other method that a lot of users tend to ignore and forget about. We are talking about the so-called file bundling. This is when the hijacker is bundled with another piece of software forming a software package or bundle. Installing the bundle with its default settings would mean getting the hijacker alongside the main program. However, if you make sure to customize the setup configuration in order to opt-out of the hijacker’s installation, the pesky app wouldn’t get on your PC. That is precisely what you should do the next time you are thinking about installing some new program – carefully look through its setup menu and uncheck everything that doesn’t look like it could be trusted.
