Alan and Aaron

Tyler Hall:

Maybe it’s because my eyes are getting old or maybe it’s because the contrast between windows on macOS keeps getting worse. Either way, I built a tiny Mac app last night that draws a border around the active window. I named it “Alan”.

Nick Heer:

I wish it did not feel understandable for there to be an app that draws a big border around the currently active window. That should be something made sufficiently obvious by the system.

Back in the System 7 days, Apple itself was working on a new design featuring thicker window borders. Users liked the forthcoming design so much that they installed the Aaron system extension to get it early. System 8 was codenamed Copland, after composer Aaron Copland. “Alan” is presumably a reference to departing Apple design VP Alan Dye.
