Hi, I just upgraded the memory in my MacBook Pro following the Apple instructions, and now the computer will not start.
Model 13" mid-2012
Memory used DDR3 1600 2 X 4 GB from 2 X 2 GB
Any and all suggestions will be appreciated.
Many thanks, Chris

Hi Chris ..
Just in case, make sure the RAM is installed properly.

Thanks, these were the instructions I followed.
1) Open it up and make certain the RAM is fully seated.
2) What RAM did you buy? It can make a huge difference. PNY, Corsair, and Kingston's "ValueRAM" are frequently found here as problematic in a modern Mac.
For over a decade I'm bought every stick on RAM that's gone into the numberous Macs in our family plus those I suuport for friends only from Other World Computing. Their RAM listings for your MBP are here:

I have their 8GB kit in my 2012 non-Retina 13-inch MacBook Pro and it works flawlessly.
