Tried to update to Big Sur 11.6.6 and yet it did not show in software update (system preferences).

then I ran disk utility and did "First Aid" on the macOS partition and finally it showed the update...

Finally, without any issues the update went very well...

Cheers...

I’m also on ivy bridge and updated to 11.6.7 today. Everything continues to work great, except my Bluetooth hardware information suddenly disappeared from system information, and I’ve lost Bluetooth functionality when I upgraded from 11.6.5 to 11.6.6. I’m a using a fenvi fv-t919 for Bluetooth and wifi. Other Specs to the left and in signature…… I’m wondering if I need to update opencore to get my Bluetooth back. New settings seem to appear in subsequent opencore releases within the config.plist.

Hi LoveAppleTimmu,
I'm not that familiar with fv-t919, but when I Google it, it use BCM94360 chipset.
Have you tried or followed the instruction from this :

Usually I update my kexts rather than upgrade my opencore to higher version since I have old computer.

 

[LoveAppleTimmu]

My kexts are updated. I’ll check out that guide. Thank you.
Bluetooth had been working fine until 11.6.6…. The chipset is still supported.
