Good if your a webdev
I'm genuinely shocked by this, thanks for sharing.
I've not stopped anyone else from commenting and have mainly replied to others who have replied to me, but whatever.
Because you are controlling the narrative, by answering every post rather than letting others contribute. It would be helpful if you delete/change your original post (saying the SSD is replaceable). It's confusing enough with Apple stuff, stating things without checking your facts. We get it, you like the macbook pro 2012, it's a good machine, parts are replaceable, very different from the new Apple laptops 2017/2018 that seem purposely designed so the cheapest parts are the most difficult to replace, like the keyboard assembly. That design philosophy makes a lot of sense to Apple, in terms of profit/servicing. The keyboard, the way it has been designed makes absolutely no sense othewise, it's one of the cheaper components, and is embedded deep within the device, yet one of the most easily and likely damaged parts in a macbook. Apple are deliberately designing stuff this way to take advantage of their customers. Nothing wrong with that per se, just as long as you're aware.
As it happens you are correct, the information that I found earlier on was listed as being for the 2018 MacBook Air but actually referred the previous generation. It was not intentional misinformation as you somehow think, not sure why your mind would automatically jump that route.
