Brett Halle sold the Apple II as a student, joined Apple in 1991, and was the first engineer through the door after Apple bought NeXT. He led the Core OS team behind Mac OS X, ran Final Cut, and quietly moved the Mac from PowerPC to Intel. This is part one of a two part tribute, in his own words.

Brett died on 1 October 2026. He was a friend of this show and a daily listener, and the best way we know to remember him is to let you he...
