I’ve been having problems with my Mac for the last couple of working days. It’s been really, really slow, and everything drags and takes an age to do. I work it hard, and have a lot of things running together so I couldn’t easily put my finger on the cause. So I had a look in the activity monitor and what did I see labelled in red? A Microsoft application. Bloody Microsoft MSN Messenger was using 98-99% of my 2.16GHz Intel Core Duo processor, which is impressive for a supposedly tiny instant messaging app. I killed it and all is good.
This explains to you why I may not be visible on messenger…
