Hey there,
Maybe it's a little late, but I just want to tell everybody that 8 Gigs of ram works very fine in a white Macbook unibody 2010.
I still work on this Macbook because it's still super quick with this configuration.
I did the same thing on my iMac from 2007 (but than with 4 Gigs because the chipset doesn't work with more ram).
I have to say that the iMac and Macbook are build from a superb quality and still works as good as in the beginning, only with a little upgrade that doesn't costs that much.
I have also an other question for you guys: what about upgrading from an HDD to an SSD (in the iMac and Macbook)?
Kind regards,
Xavier
