MSI Z490 Tomahawk + i7-10700k / Catalina 15.5.5 / OpenCore

I'll try with another USB, I don't see in the BIOS any option about OS security

So my CPU (10700 non-K) just arrived and I tried this EFI and also a couple others, including one that works on my z390 system, but all fail on my MSI Z490M Gaming Edge with:

AAPL: [EB|#LOG:EXITBS:START]

I googled and see the recommendation to update config.plist with :

<key>RebuildAppleMemoryMap</key>
<false/>
<key>SetupVirtualMap</key>
<true/>
<key>SignalAppleOS</key>
<false/>
<key>SyncRuntimePermissions</key>
<true/>

However this does not seem to make a difference for me.

I have MSI Z490 Gaming plus before Tomahawk, and it works with the same config.
Maybe check default BIOS settings for macos. Like serial-port, vt-d, etc.

I'm puzzled - another user with same motherboard as me said it works without issue for him as well. I tried clearing CMOS multiple times, tried suggested bios values, etc -- nothing seems to help ...

AAPL: [EB|#LOG:EXITBS:START] - boot just stops on this line?

Try this one. I use it as an entry point with opencore.

 

[redcweed]

yes - just stops and stays at that until I power off or reset ... I tried multiple USB sticks, tried multiple EFI folders ... i dont get it ...

Also, in this EFI put your serial number in config.

Here is a screenshot

With this key

<key>SetupVirtualMap</key>
<true/>

My motherboard stuck in the same place, only with false bootup.

this was one of the suggested changes for the same error -- let me change it back and try again ... re serial - yes added mine already
