Hello everyone, I just bought a brand new 13" macbook pro i5, it works absolutely fantastic. There's only one thing i'm not happy about: If I connect an external monitor to it (both my sharp 32" via hdmi and my 19" samsung via VGA) it starts to lag! Even on my MBP screen! Is this a lion bug? I noticed I'm not the only one who has this problem. I've got a 4 year old HP notebook which doesn't have a problem with both monitors and now my brand new expensive Macbook does. I already renamed to "AppleUpstreamUserClient.kext" and tried to run it in safe mode but with no results. Oh and if I try to logon to discussion.apple.com i get this: We're sorry. We're having a problem processing your login. 13: Jive ind not found or set. Unknown status code: 13 Return to Apple Support Communities. Can somebody help me out?
