MacBook – 16 gb RAM specs for mid 2012 macbook pro

MacBooks with replaceable RAM use typical DDR3 like any other PC laptop.

From http://support.apple.com/kb/SP644:

1333MHz DDR3 SDRAM; supports up to 8GB

The RAM you linked to:

• DDR3 SDRAM
• Memory Speed 1333 MHz ( PC3-10600 )

I cannot guarantee that your MacBook will be able to address all 16GB, since the technical specifications claim the maximum supported amount is 8GB. However, I've seen several cases in which the upper bound Apple lists as "supported" is incorrect, so it's worth a shot. Make sure the RAM you buy has a decent return policy, in case your MacBook can't use more than 8GB as per the technical specifications.

macsales.com aka OWC is a fantastic website for buying RAM. I purchased 16 gb for my late 2011 model with no problems. Order the RAM amount that you want, then when the ram arrives you must unscrew the back cover of your macbook and find the RAM to remove, which you will then replace with the RAM you bought. I highly suggest watching a YouTube video on the correct procedure to do this, as it is virtually impossible to describe the process in words. Search on YouTube: installing RAM MacBook Pro. Good luck!
