They should have called it Big Slow.

I installed the 11.2.1 update over the past weekend. My computer initially sped up but now its slowing down, slower and slower. Switching between tabs in a browser can take 5 seconds, waking from sleep can take 20 seconds, clicking on the desktop outside an application window can bring up the damn beachball. Just clicking the Apple icon to check the version with About This Mac, just now, that took a couple of seconds just to get the menu to pull down.

I looked at Activity Monitor and nothing is out of the ordinary.

Can I reinstall BS over the existing install without losing my data - like we used to be able to do with MacOS X? If not, I'd like to just downgrade to Catalina or whatever I had on there, again without losing my data.

  1. Reset SMC by following the directions applicable to your MacBook here ➔ How to Reset SMC. If that does not solve things then-
  2. Reset NVRAM/PRAM by following the directions applicable to your MacBook here ➔ How to Reset NVRAM/PRAM. If that does not solve things then-
  3. Enter ➔ Safe Mode and see if the screen issue still exists in Safe mode. Log out of Safe Mode and then reboot computer. If that does not solve things then-
  4. Finally if none of the above works then you can enter ➔ macOS Recovery Mode and reinstall the macOS and see if that solves it. One of the options in Recovery Mode is to re-install the macOS without losing data. In your case it would be Big Sur Beta version.

1. I don't have SMC, no T2, this isn't a MacBook. I have an iMac.

2. I don't have a MacBook, but all Macs have a PRAM so I'll try this.

3. Screen issue? What screen issue?

4. Why would it be Big Sur beta version? I never installed that. I haven't used a beta since OS X 10.0.

Since most of this has nothing to do with my trouble, did you mean to give this advice to someone else?

What model iMac do you have? Been thinking about the upgrade for my 2015 model (on Catalina atm).
 
the Reminders app on Big Sur macOS is the buggiest app ever. If a task is checked out whilst being repeated, for instance, daily, majority of times, it is just completely crossed out. What the deuce is going on with the said app? 😪
 
My girl friend has a Mac Book Pro 15" 2019 (i7 9880 + AMD RX 560 Pro). We upgraded from Mojave directly to Big Sure 11.0 when it was released and what a huge mistake. Since then the laptop continuously experiences these frequent crashes and reboots. None of the upgrades to 11.1, 11.2 helped. Then we did a downgrade to Mojave, after that crases appearing even more frequently. Then reinstalled Big Sur and now again on on 11.2.1. After every one to ten minutes the Mac Book is freezing and rebooting many times in a row. We tried all the tips and tricks and keyboard shortcuts found on Google, I even deleted the hard drive and reinstalled from USB Image or Internet, created a new user, nothing worked. Disk utility has dramatically changed after that downgrade, after deleting the old partitions, there are no new container or ZFS style pools created. There are only three entries under internal drive, might be a big issue? :
MacIntosh HD - Data
com.apple.os.upgrade-CE634... (Snapshot Name?)
MacIntosh HD - Data - Data

Some internet sites suggests, that after the Big Sur Upgrade, the firmware was automatically upgraded too, and now reinstalling or
Downgrading to Catalina or Mojave would not downgrade the firmware to its initial version. And that will cause lots of problems with drivers. However booting into secure mode also did nothing and the crashes persists. As MacOS is a Unix, I checked dmesg at the console after Command + S and it showed Wifi, BT and Ethernet warnings:
wlan0... Warning, invalid Wifi MAC data ...
wlan0...Warning, invalid BT MAC data ...
wlan0...Warning, invalid Ethernet MAC data ...

Luckely my girl friend has her old Windows Laptop around, so she can continuing her studies. Anybody any idea how to fix this mess? Thanks a lot.
 
Anyone on 11.3 Beta and with bluetooth audio (bluetooth speakers and AirPods) as well as AirPlay to HomePod completely broken?

Had no issues with any betas ever and suddenly with the 11.3 beta, boom! I was originally pretty excited to get the HomePod stereo output.

uhm.. why?
 
The current install has gotten so slow its just a little bit above unusable.

Under OSX we were able to do clean installs without blowing away user data and then drag apps and files from the old install as needed. Can that still be done with Big Sur? All the searches I do for that either show a bunch of "helpful" apps one can download but only from outside the App Store, or it shows clean install advice that involve reformatting the drive.

If I have to reformat and reinstall I still have a Time Machine backup that was up to date as of a few weeks ago, but that will end up installing the screwed up build that is already in the machine. Can I go back and select Catalina, for instance, but then use my file backups from last month to restore my user data?
 
Just updated my wife's 13" MacBook pro 2015 from catalina to big sur, all emails were lost, anyway to retrieve? Had to setup mail box again but only got 3 days worth back.

MacOS Big Slow is doing weird things like that. I'd quit Mail, restart, and try rebuilding the mailboxes again.

And if it doesn't work, reinstall Catalina.
 
Today, more MacOS Big Slow adventures. Mail stopped checking the server. This desktop wouldn't pull mail all day long, even when I clicked "get new email in all accounts". It finally broke free about 10 minutes ago and about 30 emails came through, some which I needed to see hours ago for business.

But at least the computer was crawling along like I was NetBooting across a dial-up connection. I'm restoring one computer to Catalina today. If it turns out ok, I'm doing the retro-grade on this one.
 
11.2.1 update seems to have completely destroyed memory management and have some weird effects. Any app I run, the system seems to take/use 2GB of RAM. If I close it, 2GB gets released back. Sometimes. If I reset the computer, more than 4GB is already being used before I even run anything.

I don't have that many apps in general (stock or third party) outside of office so there isn't anything really running in the background (checked Activity monitor).
 
Anyone else noticing the Bluetooth icon keeps appearing in the menu bar regardless if it's set to not show?
 
2018 i5 Mac Mini: 11.2.1 -> 11.2.2 update

I'm using triple monitors, and my third monitor stopped working. It seems I can no longer use two monitors on the same thunderbolt controller anymore. No big deal, I just rearranged my cables so monitors 2 and 3 are on separate controllers. (Monitor 1 is using the HDMI port. Monitors 2 and 3 use USB-C -> HDMI cables. Monitors 2 and 3 were on TB ports 1 and 3, now running on ports 1 and 2.)

My CPU is now running 10-20C hotter under typical load. This one is concerning to me.
