I am at the end of my tether with this computer now. I need to get 10.2.8 for my scanner to work so i downloaded it from apple.com/suport/downloads/macosxupdatecombo_10_2_8.html. it comes up in the screen but nothing will open up when I click on it. I've downloaded it 3 tims now to the same result. Also when I go to software update it suggests 10.2.8 and then quits halkf way through. I am seriously thinking og selling this horrible piece of stress. Please can anyone help??
