<< Solved >> How Do I Fix iMessage?

[LMSChina]

I have built my first Hackintosh recently, with a Core i5-8400, RX 580, and Gigabyte Z370N-WIFI. I replaced the Wi-Fi card with the Broadcom BCM94360CS2 using an adapter, and Wi-Fi and Bluetooth work great now! I have now successfully signed into iCloud and Find My Mac is working, but I am having a problem when attempting to activate iMessage. It tells me, "You cannot sign in to iMessage on this Mac at this time. To use iMessage with this Mac, contact Apple Support and provide the code below." I have looked at jaymonkey's post and many other tutorials on how to fix iMessage, but I still receive the same error. I have tried messing around with the Serial Number, Board Number, ROM Number, Terminal commands, and much more. Can anyone help me get iMessage working?

I ended up fixing iMessage by changing the ROM and MLB values to those of my MacBook Air.
