I use Mac OS 10.6 on a MacBook 13" (2007). It is hanging. I always see the Mac OS' spinner cursor and it reacts after 1...30 secs after clicks. So I cannot really use it despite I'd like to. Sometimes, after some minutes, it works normally, but I don't want to wait after every restart.
I don't know what could cause this slow reaction. Any system or editor prefs that could help me?
