Did you set the core count patch correctly? Also do you have the SSDT for B550 boards?

hi shaneee

i made a usb installer properly, with cpu patch as recommended.

i advance and start the installer, but after 8 minutes stop and say that installer is dammage.
(all was fine before)

i wil chck on usb key and verfiy checksum , then too prepare another installation
(my usb key version is 10.4.4)

Upload your EFI and I'll double check it.

i am mojave, and i try with imacpro1,1​

​

could be this block ? The installer runn durnig 12 min, then stop and say OSbase may be dammaged

-no_check_compat ? and argument for opencore ?​

stuck on This version of Mac OS X is out supported: Reason Mac...​

This error happens when SMBIOS is one no longer supported by that version of macOS, make sure values are set in PlatformInfo->Generic with Automatic enabled. Reminder of supported SMBIOS in macOS 10.15 Catalina:

• iMacPro1,1

Try this. Removed a bunch of stuff that shouldn't be needed to at least boot. If it works you can map the USB fresh in Windows using the USB Tool Box.

hi shanne

thanks, i start but stop quick at start of mojave with a sign STOP.

i check config.plist, i will add rx450 radeon , and too change imac7,1 to imac1,1 ( mojave with 10.4.4 )

 

[Shaneee]

Why Mojave though? Use the EFI I sent and make a Big Sur installer. Should work just fine.
