I am currently upgrade to OS X Yosemite. I find that when using app for normal work is very slow...such as email, iPhoto, etc. Currently is 2GB RAM (1067 mhz DDR3). If i increase to 8GB RAM will this help. Can i use any specs' or must stick to 1067 mhz DDR3.
MacBook, OS X Yosemite (10.10), Macbook white late 2009
