    I have a 13 Inch Mid 2012 Macbook Pro that came with 2x 2GB DDR3 1600Mhz RAM making a total of 4GB.

    However I have a Windows laptop with 2 x 4GB DDR3 1333Mhz RAM making a total of 8GB.

    Can I use the RAM in the Windows laptop to upgrade my Macbook Pro?

    In theory it should work, no problem.

    The worst that could happen if it doesn't is having the computer refuse to boot until you put the old RAM back in.

    I doubt it will work. DDR3L (L like low I guess :) DIMMs operate with lower voltages than DDR3 DIMMs.

    Your 1333MHz RAM dimms are DDR3 and 1600 MHz dimms are DDR3L technology in Mac.

    Nothing should get broken tho since you try higher voltage dimms in lower voltage machine - so give it a try and report to us. Interesting to hear if it wud work against the odds.
