So I recently came into possession of a late 2008 13in MacBook (a1278), it is the 2.4 GHz model and I am in the process of upgrading its parts to make it run better. When it comes to ram it currently has 2gb of ddr3 1066mhz which obviously is not a lot. according to apple website, it can be upgraded to a max of 4gb but I keep finding conflicting data across the web, some sites say it can take up 6gb and others say it can take 8gb. does anyone know or has tested what it can actually use? I would like to know before I purchase more ram.
