I am not a Mac guy, I have no idea what I am looking at. I am at a remote location where there is no actual tech support of any kind. The Mac Book Pro of a colleague has been experiencing severe slow-downs over the past few days. Stuff doesn't highlight anymore, response is overall slow, the Internet connection speed is crawling. My laptop (PC) works just fine when it's right next to his machine, there's no issue with the wireless infrastructure. I am not even sure where to start looking. The user says that he didn't install anything weird as far as he can tell. and that it's been getting slower over the past few days. Any suggestions on where to even start looking for this problem?
