Hello everyone. I am having problems with my blackbook 2.16ghz 2GB RAM, 320 HDD, 10.5.6. The issues are random slowdowns and lots of beachballs since yesterday. At the moment I am running iTunes, Safari, Adium & Skype only. Might add that it's Safari 4Beta and also the Skype beta. Now even at this fairly basic usage I get slowdowns in typing (the letters won't follow up), iTunes playing a song when i click it, or Safari when opening a new tab. Sometimes I will get the beachball, sometimes not. Now I have 40GB of Harddrive space left, Hardware seems ok, restored permissions, ran all the maintenance scripts (Onyx, MainMenu), followed Activity Monitor to determine potential problems, but I never get more than 50% CPU and I always have at least 500MB free RAM left (way more Page Ins than Page outs also). I know this is all very vague but I just cannot nail an issue, as most of the time everything runs smooth, but just every 30min or so I experience extreme performance problems. Maybe you have any idea, I will keep updating this when I discover more relevant information.
