Haven’t had any issues with Big Sur - reluctant to update to break what’s already fixed :)
I've been with Apple since OS X Mavericks, really never had any issues with any OS X going into macOS software. If you had no prior issues with any previous software, meaning just using it, not loading it with crap software, then you should be fine. It took me over a hour to download and install it. Just make sure you back it with CCC or Time Machine it case the unthinkable happens.
 
But does it actually fix the problem of turning a 2017 iMac into a porridge-eating snail? Will it make my computer usable again?

Running off of fully charged battery but don't think that's it since I can download a multi GB Linux distro in the background in a few minutes while waiting on Apple's slow servers.
Somehow I think there are just a few more trying to download this update than are hitting some random Linux distro's web site. Also, not Apple's servers... Apple has used Akamai for content distribution for years.

I recognize, of course, that people think they will die instantly if they do not have their own unique piece of fiber between themselves and wherever the data they think they're entitled to resides.

My two Dell’s, one USB-C, one HDMI did the same! I can see why they might go black, but the flickering really led me to believe I was out of luck.Why do these installs have to be so scary?
I am not sure if you notice, but the display mode for the flickering monitor changed to RGB during that period. As you know a bug in Big Sur caused some displays to show YPbPr as color format. I thought the flickering had something to do with the update trying to force the display mode to RGB. But alas I was wrong. It is still YPbPr.

But yeah, the flickering is some serious 💩💩 .
 
we might get that second decimal point
They're not decimal points.

macOS 11.1 and macOS 11.10 are different things, but decimal numbers 11.1 and 11.10 are the same.

The dots in a version string (the key word being string: the whole version is a string not a number) are simply separator characters, they're not significant. You could interchange them for a comma, a dash/hyphen, a smiley face, whatever. They're just to separate the segments of numeric digits, each of which is generally a whole number, but in some systems can also be a string or a string with numbers (e.g. `11.0.1-alpha1`).


What's with the numbering system? It makes it look like there's been 2 significant OS updates since Big Sur came out, when the truth is there's been 2 bugfix releases. What's wrong with calling it 11.0.2?
I predict it'll be another 2 major versions (i.e. 2 major macOS releases, so two new 'names' - macOS Big Kahoona Burger and macOS Cthulhu's Garden) before non-technical people (a) understand that this has literally zero impact on them; and (b) stop commenting/complaining about it at every new minor or patch release version.
 
I’ve got a late 2017 27” iMac with 2TB Fusion drive. Is it safe to install Big Sur yet? Read some reports that it doesn’t work well with fusion drives? I’m still on Mojave and runs fine.
Big Sur would break the fusion drive when upgrading from
Catalina. I’m still running Catalina on my 2014 Retina iMac.
 
Well, I am pretty sick of this new M1 now. I've had continual problems with it not waking from sleep. For over a month. I am set the Mac mini not to sleep and just have the display sleep. Just about every other day, pressing a key wakes the display momentarily (a $2000 NEC monitor) and then the display goes out again.

I'm gonna get this sent back at this rate, I thought the update would sort this but it's even worse.
Same here.
 
The number of times this update reboots and goes blank just to wake up again and start the process bar tells me there’s some deep stuff being updated. Probably some low-level Firmware. I’ve never seen anything like this before. It also spins fans like crazy in the 2020 13” MacBook Air (10th generation) while updating.

If your think your Mac is off because the screen is black, don’t do anything. Leave it alone. It’s doing some crazy low-level crap. After about 4 or 5 reboots, I finally got to the screen that says 9 minutes left. It took about 30 min to get here from the time it downloaded the update. About 15 minutes preparing update and another 15 minute rebooting, going black, waking up, rebooting again, showing progress bar, going black, showing progress bar again, rebooting again, etc.

Not sure if it was mentioned yet, but this update fixes a ton of security vulnerabilities, including the two zero-days that were recently fixed in iOS 14.4. Highly recommend to update immediately. There are also corresponding security updates for Mojave and Catalina.

Installing...

IMG_20210201_213856532.jpg
 
Updated to 11.2 on my M1 Mac Mini with dual Dell monitors (T3->HDMI, HDMI).

Took roughly 30mins to install. Half way through the install, one of my monitors (T3->HDMI) went black. Around 80% through the install, the other monitor started flickering with blue/white stripes for awhile. That gave me a fright!

But eventually both monitors came back normally as the installation went about and eventually it was a success.

Downloaded with no issues...my only issue with my M1 air was the Bluetooth connections

Has the bluetooth issue been resolved for you guys? My bluetooth connection with my Logitech MX mouse and keyboard has been extremely spotty. Even using the USB dongle isn't perfect.
 
Its absolute trash. It's laggy, buggy, and it sucks. It sucked on Catalina and it sucks on Big Sur.

Big Sur really trashed my 2018 Core i5 MacBook Air... I have never seen MacOS so slow as it is... I had to do clean install...
