SMBIOS setup for iCloud correctly

[w180112]

Hi, 

 

I am curious that what is the most correct way to setup SMBIOS(MLB/SN)?

 

Some "Vanilla" guild says it can be generated by multiple times random and go to APPLE website to check whether is legal.

 

Some old guild says it should be filled a real MAC's MLB and serial number with same APPLE ID.

 

However, the first "random" method I faced a problem that after the hackintosh runs for a few months, the APPLE ID associated with will tell me that due to this account involved into some security issues, I have to change the password.

 

The second "real MLB/SN" method I have used for 1.5 year is normal but the APPLE ID usually be logged out and need to re-login in system configuration iCloud page.

 

Does anyone know that? 

 

Thanks
