Q: MacBook Pro Model A1286 15" Memory Upgrade

The MacBook Pro models made in 2011 and 2012 support 16GB RAM.

Not sure but for my macbook pro 13'' in apple maximum is 8gb

Im search in web i have a mac macbook pro 13'' with 16gb ram and a samsung evo sdd

Check a Applestore or  Apple Authorized Reseller for sure and buy your ram

The A1286 model is very generic, applying to MacBook Pros all the way back to 2009. You need to specify exactly what model year you have. As the Maximum ram supported can and does change between model years.

You can use this Apple Page to identify your Mac more specifically:

How to identify MacBook Pro models - Apple Support

You can go to this page once you identify it, to find out how much RAM exactly it can take:

And no, no Apple Store, or authorized reseller will sell you RAM for your Mac, it does not work that way.

Suggested RAM sources are MacSales.com, and Crucial.com

nothing...it'll boot just fine. the reason 8 gigs was listed is that at the time, that was the biggest memory module available, and Apple tends to be somewhat conservative when it comes to these things.  You can even install it yourself. As was mentioned before, make sure you get the correct type for your MacBook Pro, and you're good to go, and no, Apple won't sell it to you

good luck

The 2012 can in fact take 16GB just fine.

If it could not, nothing would happen anyway, it just would only show up to the maximum RAM it could support, and the rest would be unused. 

It doesn't harm the computer, it's just a waste of resources.
