This page aims to help you remove MacAppExtensions. Our removal instructions work for Chrome, Firefox and Safari, as well as every version of macOS.

The annoying online ads and offers that try to persuade you into clicking on them and maybe buying some product or subscribing to a certain service tend to be everywhere nowadays. Though there are certain ways to at least decrease their numbers in your browser such as installing an ad-blocker add-on or simply not visiting the websites that show too many ads, it’s still next to impossible to fully avoid such online advertisements. However, the ads coming from websites are still somewhat bearable in most of the cases. However, if random pop-ups, pop-unders, page redirects, banners, flashy messages, links and other similar pesky advertising materials are getting shown in your Chrome or Firefox (or any other) browsers a seemingly irrespective of what site you are currently on, you may want to consider the possibility of you having an adware app inside of your browser. Adware applications aren’t something that should cause panic and intimidation in you as they are typically not dangerous or malicious and are much less dangerous than threats like Trojans, Rootkits and Ransomware. However, the constant advertising activities they are known to conduct could heavily obstruct your browsing activities and could prevent you from easily getting to the sites and pages that you are actually trying to go to. Not only that, but some of these pesky pop-ups, sales offers, ads and banners may redirect you to potentially unsafe online locations or may trick you into downloading more unwanted and irritating software by making you think you are actually downloading something useful. All in all, adware is a potentially unwanted form of software and one of its more recent representatives named MacAppExtensions proves this statement. It is, similarly to the rest of the adware family, a highly-invasive app capable of spamming you with all sorts of advertising and commercial messages. However, if you have it on your machine and need help with removing and uninstalling it, do not worry – the guide below got you covered.

MacAppExtensions Removal

Step1

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

WARNING! READ CAREFULLY BEFORE PROCEEDING!

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:

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,

Select and Uninstall any extensions that you don’t recognize by clicking on the Uninstall button. If you are not sure and don’t want to take any risks you can safely uninstall all extensions, none are required for normal system operation.
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.
Default Home Page

Select the History menu this time, and click on Clear History. This way you will prevent accidentally opening a problematic web page again.

Adware installation prevention tips

Most of the users with adware like MacAppExtensions on their computers actually have little to no idea how the unwanted software piece got installed on their machine. This is because adware apps normally do not come as a separate software piece. Instead, they typically get distributed as a part of another program – an added bonus component to some free software installer. Now, in most cases, the user would have the option to deselect the added adware app and during the setup configuration and thus leave it out of the installation. However, very few users actually have the habit of checking what added installs there are and of unchecking the potentially unwanted ones out of the installation process. However, if you do not want to have any future encounters with MacAppExtensions or any similar pesky apps, we strongly advise you to keep a close eye on what bonus added components there may be inside the setup installer of any new program you are about to install. Also, another important safety rule to remember is to only download software from sources and developers that you can trust and that are overall regarded as reliable.
