If it's a retina model late 2012 no you cannot upgrade or remove the ram it's soldered to the logic board. If it's a non retina late model 2012 yes you can upgrade it 2 16GB with an 8GB slot in each of the two ram slots.

what's awesome about the SSD, is that it's so fast in most cases it can kind of make up for the lack of ram upgrade ability on the machines that aren't upgradable because programs still open so quick.

Also what you can do, is buy a centech nvme adapter and an nvme style SSD which are three times or so faster than a standard Apple SSD. My stock SSD had a read and write speed average of about 1500 give or take. The nvme drive I swapped it out for has an average read-write speed of 3500 give or take.

to do this though, you need a little adapter from cintech which you can buy on Amazon for 1299 but certain machines when this adapter is installed, we'll hang at shut down And sometimes have a weird booting issue which there are a few fixes for by running a couple of commands in the terminal app but it doesn't really work on all machines either but on my 2013 and 2015 MacBook Pro retina has the adapter has works perfectly for both of them so I'm running a much much faster nvme style SSD which is amazing. My Mac boot shop in 6 seconds literally. with the stock SSD it was more of about 12 or 13 seconds so the booting is twice as fast and the read and write of files is about 3 times faster depending on the nvme drive that you buy. So just a little tip for people that want to get even more speed. But just know that a few Max don't like that adapter very well but there is also a newer version of that adapter which has supposedly fixed the shutdown Hang-Ups

So just a little tip for people that want to get even more speed. But just know that a few Macs don't like that adapter very well but there is also a newer version of that adapter which has supposedly fixed the shutdown Hang-Ups too. just make sure to check the comments or ask a question on the Amazon page for the adapter and make sure that the one you're buying is the updated version. only a few Max have issues with this adapter and it's usually the 2012 model and I think a few of the 2013 models. But they have adapters for the MacBook Air and MacBook Pro 13in and 15in which all have upgradable SSD drives that can be converted over to use an nvme style SSD also. So you can make your Mac fly much faster yet even much faster than the stock Apple ssd which is already relatively fast, certainly faster than a regular spinner hard drive of course. basically the adapter converts the old pin style to a newer m. To nvme pin style so that almost any nvme SSD stick will fit in your Mac, but you do have to clone your Mac first. It is stated on the Amazon page that on certain machines you can't just boot up in recovery mode when putting in an nvme drive because there is no recovery mode on it yet and even using internet recovery won't work on some machines until you format the nvme SSD, so what I did was clone my machine to an external USB hard drive, installed the adapter and new nvme drive and then boot it off my external clone and used carbon copy cloner to clone back to the new drive and then boot it up and I was laughing out loud because it was so much noticeably faster even more so than the stock SSD which we all know is pretty fast already :-)
