Summary
A developer describes how they used AI coding tools to create a Wi-Fi driver for their old 2016 MacBook Pro running FreeBSD. The laptop had been unused due to flexgate issues, and the author decided to repurpose it with FreeBSD 15. When they discovered there was no working Wi-Fi driver for the Broadcom chipset in their MacBook, they turned to AI coding assistants (Claude and ChatGPT) to help write and debug a FreeBSD kernel driver. The article details the process of using AI to understand FreeBSD driver architecture, generate code, fix compilation errors, and eventually create a functional Wi-Fi driver through iterative AI-assisted development.

· 5 pulledMy old 2016 MacBook Pro has been collecting dust in a cabinet for some time now. The laptop suffers from a 'flexgate' problem, and I don't have any practical use for it.
During the recent holiday season, right after FreeBSD 15 release, I've finally found time to set the laptop up. Doing that I didn't plan, or even think, this may turn into a story about AI coding.
The AI didn't just write code; it helped me understand FreeBSD's driver architecture, debug compilation errors, and navigate unfamiliar territory.
This experience showed me that AI coding assistants can be incredibly effective for tackling niche technical problems where documentation is sparse.
What started as a simple project to revive an old laptop turned into a fascinating exploration of AI-assisted development for system-level programming.
