> Does a binary, like lynx the browser, work over several versions of os10?
It usually will, but it's quite hard to do it right. I build a browser (TenFourFox) with MacPorts on Tiger, and it runs on every system up to Mojave. But it's very carefully self-contained. You're better off to start fresh and reinstall your ports on the new system. With Ryan's buildbots, you'll be installing rather than building mostly everything anyway. K
