macOS 10.13.2 No iMessage

[RAFFAY]

Hi guys, I have followed idiot's guide to iMessage from start to end with no result. When I enter my Apple ID in iMessage it is accepted but while sending SMS, it says Apple ID not signed it and opens accounts page in system preferences. Under accounts when I enter my credentials, it says Än error occurred during authentication

it says Än error occurred during authentication

This can be caused by the Ethernet interface not recognised as en0 and/or BuiltIn.
Another possibility is no native NVRAM support.

My ethernet is en0. As for the NVRAM, I don't understand can you tell me how to rectify it?

You may need to install EmuVariableUefi-64 and RC Scripts with the Clover installer.

No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

Use the tool mentioned in the FAQ, that way it is less likely you'll omit something.
