One of the things that has caused me to hold off is the large number of issues people are having with displays. I won't get a laptop till an Air or Pro can deal with two 27" 4k (or even 2K) monitors are trouble free. I'm hoping that will be 2021 and by that time Big Sur will be more stable with monitors. Seems to me the M1's and Big Sur are virtually beta hardware and software with all the issues people are reporting in large numbers.

I don’t know if those problems are legit or not. I have a 2014 MBP15. External monitors work great

The problems are legit. I have a LG 27 4k monitor and the color is completely messed up plugged into the M1 MBA (using usb-c -> usb-c. Some users say usb-c -> hdmi works, but I don't have one of those). Here I was worried that brew or some other programming tool I needed wouldn't work, but all of that has worked great. This monitor issue I didn't even think about, but makes my external monitor almost unusable. The colors are so washed out, the lack of contrast gives me a headache.

Have you tried turning down the brightness on your washed out display?
 
I've had great luck with Big Sur betas all the way through. But after installing this yesterday it's not working well for me. I'm suddenly experiencing weird lags and stutters (on a 15" MBP 2019). Fans came on full blast this morning and I looked at Activity Monitor to see that Mail (which was pretty much in an idle state) was using 101% of CPU. Safari Technology Preview has been crashing constantly. There still seem to be Bluetooth issues, including with my new AirPods Max deciding when and if they want to be connected. Just blergh.
It does say it’s “optimizing Mac” right after install. I did not experience any of the problems you mentioned but could it be things like spotlight indexing and such, the process completes after a bit. Also got any other software running, anti virus or anything?

I also make it a point to do a clean install once a year. With all the betas I run just feel it’s good practice. Probably overkill (harkens back to Windows days where it was an absolute life saver), but with cloud storage and keychain it’s almost painless to perform

I'm not sure 10 replies of "works for me" is helpful here. One reply stating you aren't having any of the previously mentioned issues would have done the trick.
Maybe but a bunch of complaining about everything is wrong, Big Sur sucks (when it doesn't) isn't very good either. If these are actually legitimate complaints, they don't seem to impact all uses at all, so instead of just complaining generally, how about trying something specific where people can actually see what the problem might be. for example: Wifi issues which are mentioned, is that a particular router, protocol, internet service provider, hardware problem on the Mac? it's clearly not Big Sur alone so it shouldn't be categorized as such. But you get the point, that would be helpful
 
I have this on my Mac mini with Apple M1 running macOS Big Sur 11.1 already. Works with both my AirPods Pro and AirPods Max.
Hey @RamGuy can you elaborate on how this works? I actually thought it was already enabled in 11.0 and I've been super-frustrated. I'm on my MBP a lot with my AirPods Pro and then I'll get a call on my iPhone; will the buds switch to the phone or will the phone handoff to the laptop and route the call through the AirPods? Right now I have to manually pick up on the phone and switch audio outputs.

Did you check color profiles in settings/displays? There is also a calibration tool. My colors are fine, but the color profile selected was not the one for the display, I tried a few different ones, all were fine, but some more pleasing than others

the calibration tool (same place) could correct your issues

Big sur has been a buggy mess. Hope this will address USB and Thunderbolt issues...
 
Never happened for me, but if you think that’s a thing, don’t use it or get a different mail. Seriously where do people come up with these problems that aren’t, or do they have specifics or software installs that create this?
It‘s well documented by now - if you use it for business it’s rather inconvenient. Why do I have to buy a new mail app? Apple needs to fix its mail app.
 
Have you tried turning down the brightness on your washed out display?

I played with settings on the monitor. It's not brightness. It's bad color reproduction. The same monitor plugged into my 15" mbp looks great. Take cable out, plug in m1 and it's terrible. Black colors are basically gone.

Yes, calibrated many times. It helps a tiny bit. For now, I'm using a generic profile (not the monitor one) that looks a little better. Still not great.

There's more information with pics here from others. https://forums.macrumors.com/threads/mbp-m1-and-lg-27uk850-w-washed-out-colors.2270452/
 
it fix my macbook pro M1 "touch bar light off" problem on Big Sur 11.1, along with some other problems like display off delay after sleep, crash after sleep, thunderbolt port extension through my Dell monitor. Big Sur 11.1 was like a disaster for my MBP
 
It might be overkill, but I feel a lot of users would see many of their issues go away if they reinstalled Big Sur from scratch - I did and a lot of my little bugs cleared up. But it can be a big labor intensive...

If nothing else, create a new user account and see if your bugs still exist when using that account.
 
I tried Big Sur on my iMac this week. Then I tried doing work on it yesterday and today and that seemed fine. It’s weird, but in a good way. I like the new system sounds which make it feel more lively. Think I might upgrade my MacBook Pro next which is my primary work machine. I typically upgrade in January but I’ve got nothing going on for the holidays this year, like most people, so why not?

Seems most Canon printers aren't properly supported anymore. I'm not sure how many (if any) other brands are affected, but I saw many complaints on the Apple support pages from Canon owners.
Thanks for the heads up. I haven’t tried printing yet and I need to print off Christmas photos of my kids I shot in my studio for my wife to mail out in Christmas cards tomorrow. Guess I’ll be using the MBP which is on Catalina and hold off on upgrading it.
