I really still like my iMac and Mac OS as a whole is still very good. However I also experience Windows 10 daily as my work laptop uses that OS. That work laptop also is fully managed by my employer with updates pushed to me weekly mostly to cover the latest security issue.

So I have biweekly updates at minimum to my work laptop; a nothing special i5 SSD based Dell; and these annoy me because I have to spend what feels like nearly five minutes between updates applied, boot, and more updates applied, before I can sign on.

and there is my Mac. I have a 2019 iMac, i9, SSD, and 40g memory. Twenty five to forty minutes complete with a timer on screen just to rub it in, which doesn't show up for some time into the process just to add some spice.

It is as long as the upgrade to Big Sur took or at least it feels that way. I am loathe to let my iMac update and while it claims it can do so overnight it always fails to do so.

Apple's patch process even on iPads and to an extent my iPhone are abysmal too. I really don't understand systems that are otherwise fast take so long to do an update.

PS: On a side note, Big Sur is the least stable OS from them I can recall in recent years. I have had hard freezes in some apps which they Mac three finger salute could not remedy and a few times I found myself signing back in as it just "rebooted"
