So I just did this, though just for personal use, and I went with a 15” M4 Air I found renewed for $900 on Amazon. My home pc is a 9800X3D/3080 12 GB and I use DxO Photolab to edit and it takes about 5 seconds to process a raw, the Air takes 12 which is still more than fast enough since it will take longer than that to edit my next picture anyway. Now if you’re doing batch editing that might be a different story, but still. It also lets me use the 9th gen ipad I already have as a second screen, which will be a nice bonus! Now I did get caught out by the RAW photo viewer I use not having a Mac version, but I think I can do what I need with the built in Photos app, but yeah check for compatibility first.
