Not booting

[Edwin]

Hi I’m not sure where this question should be asked so I ask it here:
I updated the bios of my MSI MPG X570S Carbon Max WiFi to the latest version and now MacOs won’t boot. I tried to change some settings like XHCI Hand-off: Enabled, MSI Fast Boot: Disabled and Legacy USB Support: Auto but no luck while booting. All I see is a black screen with the beautiful white Apple logo.
Anyone know what’s going wrong? Maybe I forgot to change a setting in bios, who knows…

If you updated to version 7D52v1A, that addresses the sinkclose vulnerability, that has been shown to cause boot failure regardless of the bios settings applied. Unfortunately the only way known to fix that issue is to downgrade the bios to a previously known working version.

Sinkclose Vulnerability Bios Updates Causing Boot Failure

Thought it would be a good idea to post that the bios updates for the Sinkclose Vulnerability apparently are causing failure to boot. There are two users who have AM4 MSI boards we know of that have that issue. It looks like a kernel issue in that the error message states: [EB|#LOG:EXITBS:START]...

Each time you upgrade or downgrade the Bios you will need to apply the AMD Bios settings. See the link below for the full set.
