Linux on Apple - success

A while back, I wrote I'd given up on trying to get Linux to run natively on my Macbook Pro Retina. The killer problem was that it didn't work reliably with my Apple Thunderbolt Display

Well, since then I sold my Apple display and bought a 25-inch Dell Ultrasharp, which is a great replacement without the Apple vendor lock-in.  So, I tried Ubuntu again (15.04) on dual-boot, following the same instructions as before, more or less. Everything's been fine. I've been using Ubuntu as my day-to-day OS for a couple of weeks now, and slowly transferring files across.

Lookin' good so far. And, more to the point, FLOSS (Free Libre Open Source Software).
