Re: It's Now One Less
Correct, it only reduces the frequency of updates, it doesn't stop them entirely.
I've also had WU force a reboot during a process that was using 100% CPU time across all cores and continuous disk access.
I'd really like to know how they decided the PC was "idle".
Fortunately I only lost a couple of hours, unlike the entire day I lose almost every time macOS updates - though at least it hasn't yet triggered itself.
Yet my Linux boxes manage the same thing in maybe 5 minutes, including a reboot to upgrade the kernel.
