I have a white 2.13 Ghz MacBook (Model A1181) that I bought in 2009. It came w/ 2 Gig of RAM. I know that even though Apple states the maximum RAM is 4 Gigs, the actual max is 6 Gigs. So I purchased a 4 Gig chip to bring my total RAM to 5 Gigs. One of my friends said I should not have spent the money b/c he had read somewhere that the MacBooks can only effectively address 4 Gigs or less of physical RAM.

I have not been able to confirm this. I would think that since my MacBook has an Intel Core 2 Duo CPU and is running a 64-bit OS (10.6.6) then I should be able to install & utilize 5 or 6 Gigs of RAM.

Can someone confirm or refute this?
