Maximum upgrade MacBook pro 13" mid 2010
Hello,
My MacBook Pro 13" mid 2010 is not really slow, but I think it can be faster. I've read that it's not very difficult to upgrade a MacBook pro by yourself. What is the maximum upgrade my Mac can handle? Can I upgrade the 4GB? Can I upgrade the MHz? I'm not really into this so maybe someone can give me some advise.
Thanks in advance!
MacBook Pro, Mac OS X (10.7.4)
