Today I upgraded my (what I believe) Revision A iMac g5 (20 inch) from 512mb ram to 1.5gb of ram. I have several questions: I downloaded mactubes yet I cant seem to do anything with it (question mark) Facebook wont fully load, just the top part of it like the notifications, message, and search. Whats the best browswer for this mac. And also I am using the wired aluminum keyboard and they sybmols like question mark, quotation mark, volume, etc. do not due their proper function. How do I get my iTunes library on this machine Its running panther. TIA!
