Here's my info:

I want to upgrade my RAM, as the computer is showing a bit of age at 3 years old now.  I looked at this support page:




And judged the installation to be easy enough for me to do, but I'm confused as to how much RAM I can buy.  The conflict I see is that "Additional notes" says I can use up to 8GB of RAM, but the table says only 4GB.  What's throwing me off is basic math -- is that 4GB only referring to my slots (thus 4+4=8) or is it saying that anything over 4GB will not be recognized by my computer?


I spoke with someone at Apple, but he seemed a bit confused by my question, and eventually gave me a "yes" that was timid enough that I felt the need to post here.  So, I'd appreciate the support!  Thanks a lot, everyone.  I'm just looking to not spend more than I need (in terms of buying excess RAM), and make sure I don't ruin my Mac in the process.
