Hi. My version of OS is currently OS 10.5.8. 2.1 GHz Intel 2 Duo Core Processor. I don't know if this helps, but maybe it'll help diagnose my problem. Basically, I went on Apples website to download the new Mac App Store. And my "Easiest Download Ever" won't appear. It tells me to go to Software Updates up on the bar. When it checks, it says no new updates are available. Pretty much like it doesn't exist. What is my problem? Thanks, Noah.
