upgrading RAM for mid 2006 white iMac
I would like to upgrade the RAM in my mid 2006 white iMac, as I would like to also upgrade the OS. Here is what I currently have:
OS X 10.4.11
Processor: 1.83 GHz Intel Core Duo
Memory: 1GB 667 MHz RAM
Is it possible to upgrade? How many OS upgrades will I be able to do? It looks like Snow Leapord is the next OS upgrade, but will I be able to do more after that?
I know how to use my iMac pretty well but I (obviously) know very little about hardware and upgrading. Am I better off beinging it to an Apple store? I checked the Store on apple.com and there was no memory to buy for my computer. Where could I buy compatible memory?
iMac G5 with iSight, Mac OS X (10.4.9)
