iMessage acting strangely lately

Hello Community,

I successfully built my new hackintosh and I have a little problem on the messages side. Sometimes when I'm in the middle of the conversation, about to send the reply I get this error: Image

Everything seems fine in my config.plist, tried to debug the problem using this guide: Guide: How to Fix iMessage Version 2.1

And... it works... at least for several hours. When I get this error message, I usually reply on my iPhone then syncs again with the hackintosh and there are two ways: a) I can continue the reply on my pc OR b) I always get this error until I restart the computer.

Here is my config.plist SMBIOS I've tried many times to generate a perfect serial number, which passes Apple's system, but never had success.

Hackintosh details:

• Gigabyte H270M-DS3H
• i5-7500

Any suggestions/ideas? Thank you in advance!
