Hello,
just want to share my experiences with Big Sur on my two intel MacBooks (13" and 15" 2018):
11.1:
- LaunchPad randomly getting new order for applications after every reboot
- external Display is going on every 10 minutes in sleeping mode, without occurring notifications or something else
- Bluetooth Stack crashing 1 time per hour
- AirPods connectivity totally broken, just have to reconnect the AirPods again and again to make it work
- shutting down the Mac isn't possible without kernel panic raised by watchdog
- artefacts on the external display, connected via USB-C -> DisplayPort cable which worked without any issue with Catalina
- 144 Hz / HDR no longer possible
- using a thunderbolt dock between the display and the Mac doesn't give the possibility to reach HDR anymore
- Safari is crashing so often, that it's totally unusable
- Bluetooth devices are disconnecting sometimes and not able to reconnect but didn't occur the bluetooth stack crash
- reinstalling Big Sur via USB Stick or Internet Recovery totally broken, three different ways to prevent installing it on a ereased SSD (also tried the iBoot recovery which worked but didn't helped)
11.2 RC:
- LaunchPad randomly getting new order for applications after every reboot
- external Display is going on every 10 minutes in sleeping mode, without occurring notifications or something else
- Bluetooth Stack crashing 1 time per hour - but now, it also crashing when disconnecting the AirPods or switching them over to another device
- shutting down the Mac isn't possible without kernel panic raised by watchdog
- artefacts on the external display, connected via USB-C -> DisplayPort cable which worked without any issue with Catalina
- 144 Hz / HDR no longer possible
- using a thunderbolt dock between the display and the Mac doesn't give the possibility to reach HDR anymore
- Bluetooth devices are disconnecting sometimes and not able to reconnect but didn't occur the bluetooth stack crash
- Dark mode auto switching isn't working anymore
- there is now delay sometimes with the bluetooth keyboard and magic trackpad which is totally ****** when you write code or text
So for me, Big Sur is totally unusable, still with version 11.2 RC and no one is answering the Radar Bug Tickets anymore.
For me, as a long term user for Apple products, it looks like the focus for the developers are now the new architecture. But that is following to me:
I got the new MacBook Pro M1 notebook and wasn't able to just create a user to login, also after recovering via USB-C cable/Apple Configurator 2/*ipsw.
