So sad this kind of shenanigans are not possible anymore.
It didn't look like a good candidate for OpenCore Legacy because of the dual video cards, but it feels so gross recycling a perfectly working computer.
I find that a lot of my work is "remote" at this point. Im doing most things on Servers, VM's, and containers on other boxes. The few apps that I do run locally are suffering (browser being the big offender).
Is most of what you're doing remote? Do you have a decent amount of ram in that air?
I still have the air with whatever the macos is, but as soon as i have a minute i'm going to try and get linux or BSD on it. I'm still sore at how little use i got out of that machine - and i got it "open box" "scratch and dent", so it was around $500 with tax. I got triple the usage out of a 2009ish eeePC (netbook)
