How to remove "This Update requires an action" popup virus from Mac

Learn how to remove ‘This Update requires an action’ popup virus as part of a procedure aimed at uninstalling the TapuFind or Chill Tab adware.

“This Update requires an action” is a popup alert that interrupts one’s web navigation in Safari on Mac. Many affected users’ first impression is that the dialog is intended to authorize the process of fine-tuning some important browser component designed to enhance their online experience. This is a misconception, though, and here is why. First off, neither the Mac’s built-in web browser nor any third-party counterpart will engage in activity as intrusive as that. The window splashes out of the blue and prevents the user from continuing to surf the Internet altogether. Moreover, if the victim is vigilant enough to abstain from clicking anything on the popup – which is the right thing to do – the browser will close down on its own in a minute or so. Sometimes the alert won’t even respond to any clicks, which is reminiscent of a garden-variety glitch entailing app crashes. It turns out, this predicament stems from an adware program called TapuFind or Chill Tab that’s already up and running on the machine.

This symptom is certainly a drag for anyone faced with it. They end up in a loop of iterative popup alerts accompanied by Safari shutdowns. Incidentally, the Mac may even reboot due to this bizarre tampering. Another fact to bear in mind is that the issue can assume cross-browser characteristics and extend its reach to macOS versions of Google Chrome and Mozilla Firefox. Aside from the inscription saying “This Update requires an action”, the uniform design of these unwelcome notifications includes a reCAPTCHA area with a checkbox next to an option that goes, “Please check the box to complete the update”. A phrase underneath this element assures the user that the message will close in 60 seconds unless they do something. As previously mentioned, it only holds true partially because it’s the browser or even the whole computer that will shut down instead.

A little bit of insight into the bug reveals that there is a potentially unwanted extension by MacAppExtensions publisher running in the browser across all the infection cases. Most of the time, the victims discover an app called TapuFind in the Extensions section in Safari or other browser that’s acting up. A less commonly reported add-on is Chill Tab. It means there are indisputable ties between the alert in question and both of these harmful applications. No matter which one of the two rogue extensions is on board, the impact upon the plagued user’s web activities spans more than “This Update requires an action” popup alone. The prey’s Internet preferences additionally undergo tweaks that cause a pseudo search engine page to appear instead of the homepage and default search. These landing pages include and

TapuFind virus extension is known to cause ‘This Update requires an action’ popup

While neither of the above-mentioned sites is malicious itself, it is visited without one’s consent. It’s because the associated extension infiltrated the Mac through a bundle of apps hidden under the hood of a single installer, and the user didn’t get a chance to find out what permissions it needs and what changes will ensue from the setup. As a result, TapuFind or Chill Tab adware abuses the wrongfully obtained privileges to modify the victim’s custom settings in Safari, Chrome or Firefox in such a way that the affiliated web page is recurrently resolved. If a keyword is entered in it, the online traffic will be forwarded to Bing or Yahoo while traveling via a number of ad networks along the way.

The reason why “This Update requires an action” popup keeps showing up may appear somewhat vague. Again, it crashes the browser, and that’s not the goal Mac viruses pursue. Furthermore, most people cannot enable the ReCap checkbox because it’s inactive. The main theory in this regard is that the alert is intended to cloak the installation of more malware, serving simply as a red herring. Another plausible scenario is that the underlying adware is actually trying to update itself to a more sophisticated version, but fails to do it due to a misconfigured server or poorly written code. Either way, the popup activity is extremely annoying and considerably diminishes the victim’s Mac experience. Therefore, the harmful code that triggers these alerts should be removed immediately otherwise the damage may inflate over time.
