Same here. I am having problems with Big Sur too. Frequent reboots, unexpected logouts. This mainly happens when I open some pages with Chrome

When you are using iGPU display out, please try to set iGPU as primary in BIOS. That did the trick for me.

Hey guys, any update? I want to update to big sur but it sounds like everyone is having some issues.

[rosperling]

I'm currently using Big Sur for evaluation. The stability really depends on your setup. At least for me I can confirm that there is no problem in general with the stable release of Big Sur and OpenCore 6.3 - so take release 3.9 and test for yourself.

What I found out, is that there are indeed some incompatibilities between apps and Big Sur. For example my beloved digikam for photo management isn't starting up at all. But this also happens on a real Mac. So there is nothing to blame here.

I'm using an i7-10700k, a RX570 and a iMac20.1 profile with HDMI output via iGPU for a second monitor - mainly to save power since the RX570 takes 40W in idle more to power the second screen.

I can confirm, that OpenCore 6.3 (release 3.9) introduces much more stability into everyday life.

First I tried updating to opencore 6.3 and the big sur upgrade. Fails pretty quickly after rebooting and booting up into the install environment. Went back to the older version of opencore I had and it got a lot further but still fails on me. Anyone having problems with the upgrade as well or just post install issues?

This one of the first configs i tried with Big Sur. I could never get it to work on this one but this was about 2-3 weeks ago. I see some updates have been done since but for sure there is configuration changes needed for Big Sur over Catalina. I'm not sure what edict is on pointing to another persons config so if you want to delete I understand. I used the on https://www.tonymacx86.com/threads/gigabyte-z490-vision-d-thunderbolt-3-i5-10400-amd-rx-580.298642/ and still modified it a little bit. I also found out from his forum that if you are having sleeping issues and have one of the PCI cards for using one of the Mac Mini's Wifi / Bluetooth cards for additional Apple features. That some of them will keep your computer from sleeping properly. They list a board that severals say work for them.

I'm now using the same config but with the enabled intel wifi/bt. I had to change the platform_id to enable full acceleration with the UHD graphics together with the RX570. So far it is very stable.
