I am a new mac user and for some reason every single time I try to chat with friends using skype or QQ(Chinese skype) I get disconnected over and over and over again. There are also constant issues where my messages fail to be delivered and I know this is not a problem with my internet connection because this NEVER happens when I use my PC to chat with people on skype and QQ. My PC needs a new hard drive, so I am stuck with only using my iMac and it is driving me insane because I can't even chat with my friends. Are there any Mac experts on here that can PLEASE help me out with this?
