The Linux project continues.
Bonus learning: you'd think older machines would struggle, but I've seen no post-install h/w issues on my 13-year-old MacBook Pro: wifi, bluetooth, ethernet, screen, touchpad, keyboard, speakers...
I suspect age is a benefit to a point, the Linux community having had more time to solve things, subverting Apple's planned obsolescence and urge to sell more regardless of environmental impact.
Here's a pic to celebrate.
