I used to not care about this much, but Big Sur has been so awful and buggy for my business that I'm pushing every upgrade ASAP. Maybe they'll finally finish this operating system by the time the new MacBook Pros launch. ?

It’s absurd to me that patching the browser requires an OS update. I mean, come on Apple, you created the App Store, a seemingly perfect tool for update single applications like this without requiring a reboot ?
