Answer to: Can I insert 16Gb RAM into MacBook Pro early 2011?I just added 16 gigs to my early 2011 MacBook Pro and when from slug to a race machine. It also improved the internet. If you upgrade look at the activity monitor and it actually uses over 10 gigs to operate. I used consair Mac memory. My machine slowed with each OS upgrade and I think it's Apples method to tell you need a new machine. I use a lap link cable to capture pictures from my camera Raw files and now it works great.
