When Changing SMBIOS, what else do we need to do (with Apple ID, iServices, etc)?

Hi,

I have Asus Z790 ProArt, 14700k, using built in intel wifi AX211. Have read that people have best chance of success with iMessage, FaceTime when using 7,1 SMBIOS and using Itwlm. I would like to try this approach.

I initially installed Sonoma using 1,1 SMBIOS. All is well. Didn't want to use 7,1 BIOS, but figured may as well test it. So if I go that route, do I need to reinstall Sonoma, or is it just a matter of generating new data with genSMBIOS, updating config.plist, clearing NVRAM, rebooting?

thanks
