Apple Seeds First Beta of macOS Big Sur 11.2 to Public Beta Testers

I hope they get around to fixing WindowServer's excessive CPU usage soon. At idle it consumes around 6–8% on my old MBP 2016, but simply moving the cursor causes CPU usage to spike.

If you have a mouse with a high polling rate (i.e. a gaming mouse) it goes from bad to awful. With my Logitech mouse set to 1000 Hz (the default) WindowServer can easily use a full 100% of a core! Even with the polling rate lowered all the way down to 125 Hz there is still 30–35% CPU usage with nothing going on except a moving cursor.

I can't recall any of this being an issue with previous versions of macOS. Even 1000 Hz poll rate didn't cause WindowServer CPU usage to go much above its typical idle state.

Have you tried this version, 11.2 public beta? I have a Logitech G9x and i have this behaviour with 11.0.

I hope it fixes the printer drivers issue.

Not sure if this will help, but I was having problems with my printers, and I thought it was a Big Sur Beta problem. Turns out it was my new Xfinity XFi Gateway. I had to go to the Gateway settings and enable "zero config" which then let my AirPrint printers work again. Again, not sure if this will help, but I haven't seen this solution mentioned much.

With Apple giving less for older Mac computers when trading them in they need to keep the Intel side of the software running great. I think they went the wrong way for turning in old Macs for getting new Macs with the M1 processors. If they want more Mac users to adopt the new M1 technology they should have given more for your old equipment not less. Why should I go to a still new M1 processor when I can use a hardware and software proven over the last 15 years? Looks like I will be keeping my MacBook Pro 16 for a extra year with the decrease of the trade in cost by Apple.

After using Big Sur for development this is the first time I'm pushing off updating my main systems (Mac Pro's). There are still too many opened and acknowledged bugs and the UI is a mess. I've also read some are experiencing issues with Big Sur display resolutions. I have a 2013 Mac Pro with dual D700's and two 5K UltraFine displays running in 5K. I'm worried that updating will screw up my setup on this Mac Pro (have a current gen 2019 running Catalina I'm hesitant to update as plugins for a lot of my work won't run on Big Sur). I'm tempted to update this Mac Pro esp as 11.2 may address some of the issues but nothing of note appears in the logs.

I don't mind sticking to Catalina and waiting until 11.4 if it means stable performance.

Every version of Big Sur has been better than Catalina for me. I know I'm a bit of an outlier, but I was ready to do an erase-and-install when I was on Catalina. I tried an early beta of Big Sur and it fixed those issues... and I haven't looked back since. A few hiccups/app compatibility issues at first, to be sure – but now things are running very well.

Works fine for me. Is your problem app specific?

I have an issue with all the dialog boxes in all apps (open, save as, export, etc...) where it doesn't save the size and position you last opened. It always opens at the default setting, really small. I've had this issue on my iMac Pro and MacBook Pro ever since the 11.1 update.

Me too on MBPro 2017 and MBAir 2018 on 11.1. What about on 11.2????

This beta has been a buggy mess for me. Crashes or freezes constantly when opening an app, sometimes it doesn’t want to boot up. This is as buggy as the first beta for Big Sur. I’d avoid it

Has anyone sucessfully downgraded from 11.2 back to 11.1? 11.2 feels not completely stable.

I unenrolled from the beta and reinstalled from the Big Sur 11.1 release version from the App Store.
Safari won't run. It's still version at 14.0.3 which requires 11.2. I can probably FrankenMac it back to Safari 14.0.2. However, I wonder what else hasn't properly reverted.

Word of warning, 11.2 might be a one-way trip. If you have an M1 Macbook, you might want to hold off on the beta.
There's something also that prevents Apple Configurator from re-imaging the machine succesfully back to 11.1.
There's potential you could brick the machine.

In my case it hasn't been approved or ready to use according to our company IT, because it breaks a whole lot of stuff like VPN and Firewalls. We’re seeing any third party KEXT loaded causing all sorts of issues with the upgrade process, with stability and general crashing /Kernel Panics.

So no. I wouldn't mind trying it out on a private terminal, but when it comes to my daily driver better safe than sorry.

Hopefully they fix the issue where if you have the “optimize streaming on battery” Checked, it causes Apple TV and other videos to flicker and skip when you’re watching it full screen

What do you think the chances are of getting another public beta update before Xmas? This EDID/resolution bug with multiple external monitors is absolutely killing me.

better in 11.1 but not entirely fixed. when connected to an external monitor with a youtube video playing (im using firefox), it can easily get fans spin up.
