Apple Platform Security Alert

Apple Platform Security

Apple Platform Security is an aggressive advertising Mac app that is aimed at popularizing certain sites by forcing your browser to page-redirect you to them. Apple Platform Security is usually included in installation packages and distributed alongside other apps which allows them to get installed on more computers.

If you are already familiar with this app because it has gotten installed on your Mac, you are likely forced to put up with dozens of ads swarming your screen every time you start a new browsing session. In addition to that, it is likely that elements of your browser such as the main search engine and the homepage and new-tab page have been modified without your permission. Those are the most noticeable effects that a browser-hijacking app such as Search Marquis, QSearch could have on users’ browsers and one could experience them on Safari, Chrome, Firefox, or any other Mac-compatible browsing program.

Even though this hijacker isn’t an inherently harmful app, it should still be uninstalled from any Mac where it’s present because of the potential security issues it may eventually lead to.

Apple Platform Security Alert for Mac

Apple Platform Security Alert for Mac is a browser add-on app that is labeled as potentially unwanted due to its endless attempts to aggressively promote different sites inside the browser. Apple Platform Security Alert for Mac can be described as a Mac browser hijacker that can modify browsers without user permission.

Every time a given app makes any changes in your system or browser without your informed permission, this should raise a red flag in your mind that the app in question should probably not be allowed to remain in the computer. In the case of Apple Platform Security, this browser hijacker is likely not going to directly damage your Mac PC. However, its generation of sudden page redirects and aggressive ads may potentially result in more serious security programs. The main reason for this is the unverified nature of the sites and products promoted by the hijacker. Unfortunately, it is possible that some of them are unsafe and may even be used for the distribution of malicious software threats, including spyware, Ransomware, or Trojan horse viruses.

What is Apple Platform Security?

Apple Platform Security is a type of software that attaches to the browser and begins to spam it with obstructive popups and banner ads and aggressive page redirects. Apple Platform Security is considered to be unwanted and should be removed immediately or else its advertising actions may expose your Mac to more hazardous software.

In the worst-case scenario, you may get attacked by some harmful Trojan horse virus or a Ransomware infection, but even if this doesn’t happen, the unpleasant ads, the obstructive page redirects, and the unwelcome browser changes are still enough of a reason to uninstall this undesirable hijacker.

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:

    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,

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