I need help with iMessage

Hi fellow hacintoshers,
I have recently set up my own hacintosh, with small help of my friend, but since day one I couldn't log in to iMessage. First time when I asked my friend what to do he sent me a guide to fix it. After doing this guide 4 times I still didn't manage to get it working, and my friend doesn't know what to do either at this point. My recent thought was that it does not work because my rig has been missing bluetooth and wifi card, but now it does, and it is still not working. My computer doesn't support nvram natively, I got it working with EmuVariableUefi + rc scripts.
At this point I lost all my hope of fixing it by myself and now I'm turning to you, hacintosh community, for help.
