Bought a Darter Pro last year, newest version, and as a long time apple user I just want to say: beware, the build quality is another ballpark. There is a reason mac books are 1k more expensive, they are that much better imo. Even with the shitty butterfly keyboard.
Not trying to shit on System76, it is a fine laptop and in a couple of ways better than a mbp, just not as 'premium'.
Oh, and they have no resale value, I getting offered ~20% of the new price for a laptop that has only been used for a week. Not surprising really, small market and all. And here (NL) nobody knows System76.
