How to remove "Your Mac needs to be updated to improve compatibility" from Mac?

What is "Your Mac needs to be updated to improve compatibility"?

Similar to "Apple Wants To Make Changes", "Your Mac needs to be updated to improve compatibility" is a pop-up message encouraging Mac users to install updates that will improve computer compatibility. Recently, many users started encountering this pop-up. Be aware, however, that this is a scam and should not be trusted.

Your Mac needs to be updated to improve compatibility scam

The "Your Mac needs to be updated to improve compatibility" pop-up window encourages Mac users to enter their username and password to install updates that will supposedly improve the machine's compatibility. This is a fake pop-up window and Apple has nothing to do with it. Genuine pop-up windows/messages by Apple do not contain "Your Mac needs to be updated to improve compatibility" or other similar phrases. This fake message relates to the weknow.ac browser hijacker and is a fake version of a genuine MacOS message called "Finder wants to make changes" (this usually appears when accessibility permissions are required). Furthermore, genuine pop-up windows are caused by operating systems, not by browsers (web browsers are not capable of generating operating system pop-ups). Fake pop-up messages such as "Your Mac needs to be updated to improve compatibility" are usually caused by rogue applications that are installed on systems. Scammers (cyber criminals) use fake pop-ups to steal account details that are later used to perform malicious actions (that require certain permissions). Therefore, we strongly recommend that you ignore "Your Mac needs to be updated to improve compatibility" and do not enter the required information (username and password).

Most potentially unwanted applications (PUAs) deliver intrusive ads (such as coupons, banners, surveys, pop-ups, and so on). They display them using tools that enable placement of third party graphical content on any site. Therefore, the ads conceal underlying content of any visited website. By feeding users with these ads, PUAs diminish the browsing experience. Furthermore, if clicked, they often redirect users to malicious web pages and sometimes execute scripts that download and install other unwanted apps or even malicious programs. Generally, ads delivered by unwanted apps cause computer infections or other unwanted installations. Another downside of PUAs is that they often collect browsing-related data, such as keystrokes, search queries, IP addresses, URLs of visited websites, geo-locations, and so on. They also collect personal details. Developers share the information with third parties (potentially, cyber criminals) who misuse it to generate revenue. Therefore, installed PUAs can cause problems relating to privacy, browsing safety, or even identity theft. If you encounter redirects to "Your Mac needs to be updated to improve compatibility" pop-up windows, check your browser for unwanted applications and remove them immediately.

There are other fake pop-ups similar "Your Mac needs to be updated to improve compatibility", however, most do not request a username and password. Typically, they make false claims about the system being damaged, infected, and indicate that certain files are missing, and so on. The purpose is trick people into purchasing products or services ('technical support' or similar), which will supposedly help to solve the problems. Potentially unwanted apps also share many similarities. Developers promote them as providing 'useful features', however, these are merely attempts to give the impression of legitimacy and trick people into downloading and installing them. Most of these applications do not provide the features promised or any other functionality - they are used simply to generate revenue for their developers.

How did potentially unwanted applications install on my computer?

Some unwanted apps have official download websites, however, most are installed through intrusive advertisements or when developers use a deceptive marketing method called "bundling". Bundling is used to trick people into installing potentially unwanted apps together with regular software. This is usually achieved by not properly disclosing information about the presence of these apps in set-ups. Developers hide PUAs in "Advanced", "Custom" and other parts of the download/installation procedures. Furthermore, many users do not check all available settings and skip installation steps, thus leading to unwanted installations.

How to avoid installation of potentially unwanted applications?

Do not download software using dubious/untrustworthy sources, third party downloaders, and other similar sources. Use direct links, official and trustworthy websites only. Check "Custom"/"Advanced" and other options and settings when installing software, especially freeware. Decline offers to install PUAs and only then finish the installation process. Bear in mind that advertisements may seem legitimate, but many redirect to dubious, untrustworthy or even malicious websites (for example adult dating, gambling, pornography, etc.). If you encounter these redirects (or ads), check your browser for any suspicious/unwanted plug-ins, add-ons, and extensions. Also check the list of installed programs on your computer. Uninstall all unwanted entries from your computer and browser. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
