@ekson.Hi guys I am new here. This is my first post as well. I have had success installing Mavricks on my HP. All is well except my imessage is stuck at logging in. It does not give me any errors just loads and loads. I have left it running all night and woke up to the same thing? Any ideas would be appreciated. My icloud and app store is running fine, just imessage and facetime is giving me problems. Thanks for any feedback!
