Although it didn’t affect every app, as I use both MarsEdit and Messages a lot, I often wasted time undoing these errors and restoring order to my windows. Having clicked on its window to bring it to the front, the next click(s) were misinterpreted, usually causing that window to jump, and when a double-click to hurl it into into full-screen mode. The first of those affected MarsEdit, sometimes Messages, and a few other apps. Two that spring to mind are misinterpretation of clicks/taps, which could send the windows of some apps flying across the screen, and the misleading charge figures displayed for Bluetooth devices such as wireless trackpads and keyboards. Among the bugs fixed in 12.0.1 are several which have either been damaging to workflows or downright annoying.

The last version of Big Sur to receive any significant fixes, other than those of importance to security, was 11.5.2, released in August, over two months ago. I’ve already explained why this is a bad choice as far as bug-fixes go. If your Mac is currently running Big Sur or any earlier version of macOS, it’s far easier to watch what happens with Monterey over the coming couple of months before making any decision about when to upgrade. The safest choice is so often to stick with what you’ve got.
