ZoomIt for Mac: How AI Ported a 20+ Year-Old Windows Tool
AI enabled a solo developer to port a 20-year-old Windows tool to Mac in one weekend
“Prior to AI, I would have never even considered and I nevered considered doing this because I would have had to learn so much about Mac.”
A Microsoft developer used AI to incrementally port ZoomIt, a 20+ year-old Windows Sysinternals tool, to macOS over a single weekend using roughly a dozen prompts per feature. The project, released open source on July 24th, demonstrates AI eliminating the platform-expertise barrier that previously made such ports impractical for a single developer. The case is a concrete, first-person account of AI expanding individual engineering scope rather than just accelerating existing workflows.
