The parent post is a microcosm of why he's actually not using the Macbook - he doesn't understand how it works.
Oh, I understand. I don't agree with it.
Also you can disable autocorrect. I don't even have this list.
Oh and to be clear, this isn't one of those Windows things like "oh just disable this in some hacky unsupported regedit way, how did you not know this," or the default browser setting that flips itself back, or other settings that it'll nag you to change back every day. I mean MacOS has a properly supported setting for this and I haven't seen an autocorrection in years.
