I Need help with

Hello, i've just finished to create my EFI for MacOS BigSur. The EFI are actually OK but when i start the PC (DESKTOP i7 4790k, 16GB Ram DDR3, Intel HD Graphics 4600) and i select the BigSur installer, it block himself with this string:_dlil _attach_flowswitch_nexus_en0 1500 1500

Some people says me that i've used the wrong SMBIOS but i didn't find another one that it could work.

Can someone help me? (The SMBIOS that i've used is iMac14,4)
