Sparkle is amazing. For years and years, I thought it was actually part of the OS, as almost every app I had used it. That's how ubiquitous it is on the Mac! Edit: Very interesting! The guy behind Sparkle (Andy Matuschak) is actually an Apple employee, working on UIKit! http://andymatuschak.org/ http://andymatuschak.org/ > By day, I work on UIKit to help other people make things.
