Ok I'll try and make this short and sweet: A good friend of mine (who I have just recently converted to apple) bought his first mac, the air after seeing that he really like it while using mine. His work applications (some allstate insurance app) is only compatible with windows. No problem, just dual booted with XP and OSX. So that solved that problem. And everything worked great he said for the first 4 months. After that, anytime he uses OSX for the INTERNET it runs so slow. Everything else runs very smooth like it should. And when he boots up with XP and uses the internet there it runs great; fast and responsive. So what could be wrong? I suggested do a complete backup (he has time capsule also) and then wipe everything and reinstall. He is hesitant do that since he and I aren't sure if his work program would be included in the backup. So then I created a test account in OSX to see if the internet was working better on another account....but it wasn't. So I am out of ideas. Does anyone know if his work application would be included if he went the back-up and wipe route? Any suggestions or advice?
