Hi
@pastrychef
A dear friend of mine has an Asus RogStrix B360-I with i3-8100 (no other GPU, it uses HD630 iGPU and it works as MacMini8,1 sysdef) that has worked pretty well during the last 3 years under BigSur. Last week it was updated to the the OC 089 and then upgraded to the latest Monterey 12.6.3 . The system has been working well for around 1 week now with Monterey but, as of today, it presents a really strange behaviour: the boot process works fastly and smoothly till the logon window and then, after logon on the main profile, everything is frozen up, there is the spinning wheel everywhere and the dock bar doesn't work, finder doesn't launch up and anything is pretty extremely slow. The system is unable to either shutdown or restart. The other 2 profiles don't even log in. The only option is to hard reset the machine.
I've tried to clean NVRAM with both the options of OC but nothing changed. I went in the Recovery Partition and the boot disc (APFS) is absolutely clean and healthy. I tried to boot with the USB stick (same 0C089) but nothing changed. I've even booted in safe mode (-x) but nothing has changed. I really don't know what to do... I'm posting the EFI... do you have any hint? Thanks!
