16GB works in that 2012 MacBook Pro.

Yes, you can use two 8GB sticks for 16GB total. Apple officially says 8GB max, but that’s a conservative spec from back then — the hardware handles 16GB just fine.

The 2012 13-inch MacBook Pro (non-Retina) uses standard DDR3 SO-DIMMs. Grab a matched pair of 8GB sticks at 1600MHz (PC3-12800). It’s a cheap upgrade and makes the machine feel way snappier for basic tasks.

Just know some older firmware versions might be picky about brand or timing. Samsung or Crucial are safe bets. If you get boot loops, reset the NVRAM/PRAM and try reseating. Usually works first try though.

Your old MacBook will thank you.
