3 system:

thanks for your guide and success boot up. this may be an example for others.

by the way, I get path from IORegistryExplorer .

I don't know what that use for. could you explain that to help me understand?

[TylerLyczak]

Hmm, that's a weird path. Any kexts you running to change the path? For the DefinitionBlock, I would change it to DefinitionBlock ("", "SSDT", 2, "ACDT", "SWDS", 0x00000000) Also, I would change the file to SSDT-SWDS.dsl since you are not even changing the BRG0 path

[kernelai]

I just using a few kext which download from origin officialy. . so don't know did I change it actually.

[kernelai]

you are right. I should change file SSDT-SWDS.dsl
