hello I have 1.2.5. trying to log in to multiplayer servers and keep getting internal connection errors on my mac. did extensive google search and can't find anything that works. I would really appreciate some help. thanks
Just update your client to 1.3.1, the internal server error is because the server doesn't recognize your client, because it's outdated, if you don't know how to update, then I just want to keep my dignity, Google doesn't care, ask the question about how to update to Google...
if you have 1.2.5 and you downgraded from 1.3.1 it is impossible to log into any existing 1.2.5 servers. If you're trying to get into a 1.3.1 server you just force an update when logging into minecraft.
