I run a IMAC Snow Leopard 10.6.8. A few weeks ago the "beachball" started spinning only just every so often but it's getting more and more. Now it seems like every time I click or scroll with the mouse it starts and lasts for around 10 seconds. I've used onyx to clean the caches etc. My system memory on the activity monitor is VM 132.65gb. size free--9.3mb and active 915mb. wired 673 mb inactive 461mb. The page ins 1.39gb page outs 1.41gb. swap used 2.82gb. I'm not really sure what all that means. Spinning beachballcame on a few times as I typed this message. Thank you
