Apple Again Tests Background Security Updates in iOS 26.3 and macOS Tahoe 26.3

Apple is once again testing its new Background Security Improvement feature that first rolled out in iOS 26.1, iPadOS 26.1, and macOS Tahoe 26.1. Following a previous test earlier this week, developers and public beta testers who are running iOS 26.3, iPadOS 26.3, or ‌macOS Tahoe‌ 26.3 can now install a second Background Security Improvement update for testing purposes.

Apple says Background Security Improvements provide additional security protections between software updates for Safari, WebKit, and other system libraries.

Background Security Improvements can be installed by going to the Privacy and Security section of the Settings app, scrolling down to Background Security Improvements, and selecting the "Install" option. If "Automatically Install" is toggled on, Background Security Improvements will be automatically installed when they come out with no need to manually install them.

Apple says that users who opt not to install the Background Security Improvements will receive the updates in a standard software update.

Apple previously had a Rapid Security Response update feature for delivering security improvements, but it wasn't used often after it was introduced in iOS 16, and was ultimately phased out in favor of Background Security Improvements. At one point in 2023, there was a Rapid Security Response bug that prevented some websites from displaying properly.

Apple warns that Background Security Updates can result in "rare instances of compatibility issues." Should that occur, the updates may be temporarily removed and enhanced in a subsequent software update.

I'm sorry, but based on Apple's poor software quality I do NOT ever want a security update to happen in the background or without my specific authorization.

So… turn it off?
Also, they can be removed after they are installed just so you are aware.

My income is based on my Apple devices working, not being bricked when I need them most.

But Apple is just prepping for a time when there will not be any choice. They have a constant history of removing options.

So "turn it off" works for now, but what about later?
First of all, this feature has been an iOS for four years now and you’ve always been able to turn it off, even though Apple hasn’t really used it. And they specifically state you can remove the security updates in case of compatibility issues, and you will get the security update in the future software revision.
But also… Why are you worrying about some hypothetical that might maybe possibly but also might possibly not probably won’t happen someday?
For now, they are removable, and you can turn the feature off.
If that policy changes, cross that bridge when you get to it, literally absolutely no point in fixating on it today.
It’s like the complaints in 2010 that Apple was going to make macOS “AppStore only” and your finder and terminal and all of your cool computer things are going away. It’s been 16 years and you can still download apps to your Mac from the Internet and fly through Finder and use the terminal to your heart’s content. You can even do those things at the same time..

Make no mistake, they really wanted to do this.

But I think they realized it would have been the end of the Mac.
And your source is?
Or is this another “just trust me bro” straw man.
