Re: The sorry state of Apple's garbled App Store Update Page: High Sierra.
Dude, calm down. You may want to read the thread you are the OP of before directing me to read a thread on the Apple discussion forums.
If you notice, I'm directly replying to 'Richard 12', who said:
"Every Apple update burns an entire day of my time.
Some of them have burned two - 48 actual hours.
Yet Windows Update hasn't taken more than 20min of my time for a decade.
Yes, sometimes they go wrong. But the above macOS update times are all when it went right."
I was just letting Richard 12 know my experience (as others have also done) and letting him know that what's happening to him is not the norm. I'm just trying to give him a pointer that maybe he should check if his hardware / software install is OK if updates are taking 48 hours. So it wasn't directed at you at all.
I actually largely agree with what you have written as my Mother has an older iMac that relies on High Sierra. Unfortunately MS are also 'end of lifing' versions of Windows 10 at an even greater pace. Windows 10 versions 1909, 2004, 20H2 and 21H1 only receive around two years support before they reach end of service and are no longer updated. Granted they do have long term support releases (1507, 1607, 1809), but that's for Enterprise only. Unfortunately, whether we like it or not, both MacOS and Windows are going over to being rolling releases and once they are out of service, we are out of luck. Doesn't mean we have to like it, but that is the way things are going.
Ironically, as if to prove the point I made in my first post, after posting that comment I remembered I hadn't used my dual boot Surface machine in about six weeks, so thought I should probably update the Linux and Windows installs on there. I first updated Linux. Two bash commands later and around 10 minutes I'm fully up to date. I then booted to Windows, which spent 45 minutes stuck at 74% installing a 'Windows Cumulative update', finally it finished and then restarted, which took another 10 minutes on the blue 'installing' screen. I went back to update again, it said 'You're up to date', but I clicked the 'Check for updates' button anyway. Up pops another two or three updates. I install those and restart again (thankfully only about 15 minutes this time) and then check updates again. Yet another update! Only a small one though and thankfully that was the lot.
