It's time to update your Mac… again.

macOS Big Sur gets what might be its final update before macOS Monterey is released. And it's a biggie.

Clocking in at over 2.5GB, Apple describes Big Sur 11.5.2 as "bug fixes for your Mac."

Do you need to rush out to install this, and are there any gotchas or catches to installing it?

I've been running this since its release, and to be honest, apart from the change of version number, I can't see any difference. Performance is the same, battery life is the same, and reliability is the same.

On the "how much of a hurry should I be to install this?" front, according to Apple ", this update has no published CVE entries," which means that unless you're being plagued by some bug or other that you're awaiting a fix on, you could hold off updating for a while (as long as you're up to date on Big Sur 11.5.1, which contained some pretty important security updates).

To update macOS, click on the Apple logo in the top-left corner, go to System Preferences, find Software Update and download and install any available updates.


Having set this up on a system where I was paying attention to the setup, I noticed that on first boot up users are given an option to set up accessibility features, and to set up Apple Pay on their Macs.
