Greetings all, My Santa Rosa 2.2Ghz Blackbook has developed an interesting problem, which I noticed after installing the new Safari 4 Beta. It's only showing one CPU. Profiler and Activity Monitor both show the same thing... and while this is strange, everything is running fine (perhaps a bit slower, but i have been thinking the comp was being a bit slower in recent weeks). I can't say for sure that Safari 4 had anything to do with this, the only connection was when I noticed the problem. I have uninstalled Safari 4 (and rebooted), but the problem remains... Can anyone help me out? Similar experience, explanation, or how to resolve this? Thanks.
