@ActionRetro I did exactly this for my bedside computer that I use daily. Mine was the 2011 13" MacBook Air but with the same specs. I originally kept it going once macOS wasn't supported by trying ElementaryOS. Now it runs Garuda. It had its battery replaced several years ago but it is still going strong. Since it is just used for internet browsing and playing YouTube/PeerTube videos it is more than adequate still. I wonder how many more years that will be true.
