I just upgraded my Macbook Pro mid 2012 from the 4 GB memory sticks it came with to 8 GB, but only 4 is showing up on "About this Mac" and Activity Monitor. Should I open my computer again and check that the memory is OK, or is the computer programmed to only show 4 GB?
macbook, Mac OS 8.6 or Earlier
Just ran NVRAM reset, RAM not found.
I would check that the memory is installed properly. While delicate, the RAM sticks are tougher than people let on. I expect one is not quite seated perfectly, or these is dust/dist in there. They must be very precisely installed and very clean.
You do have the right kind?

Thanks. I had that on my mind for things that may have gone wrong, but I wanted to make sure there was not a software thing I forgot to do before opening my laptop up too many times. The bottom chip was a bit crooked.
