I figured out a solution for GTalk to work on High Sierra
Go to system settings and go to Internet Accounts and delete your google account.
Open Terminal
find ~/Library/Preferences -name "*iChat*" -delete
then
rm -rf ~/Library/Caches/com.apple.Messages
then
rm -rf ~/Library/Messages
and reboot
Now open Messages and add your google account via Jabber. Then go to preferences in Messages and go to Accounts and go to server settings and make sure settings are as follows:
Server: talk.google.com
Port: 5223
Check Use SSL
Then go to Account Information and Enable this account
I rebooted again and then opened Messages and made sure my buddy list was there.
Then I went to System Preferences and go to Internet Accounts and add your google account.
Upon doing this a message popped up for me asking to Add Google Talk to Messages and WHOA it is working.
I can now send and receive messages, have my calendar and everything as before.
Before this I could receive messages and see buddies but couldn't communicate with them.
Hope you have the same success I did doing this. Now if I can get AIM to work I would have it all working lol
