Ask HN: What are you working on? (February 2025)

I’m selling refurbished and upgraded Mac mini G4s as the ultimate machines for running software for the classic Mac OS over at https://os9.shop

Over at macos9lives.com a group of hackers figured out a way to get Mac OS 9 running on these late model G4s that previously never supported it. That combined with an SSD upgrade makes them close to the fastest machines that can run Mac OS 9.

I’ve taken advantage of this hack, now having sold about 80 -90 machines. But I’ve hit a wall with finding ways to advertise it. eBay has been okay. I tried Reddit Ads on the vintage Apple subreddit and they were so so—probably lost money doing it but got the word out. Google Search ads have surprisingly been ineffective. I’ve posted on various vintage Mac forums but they don’t allow formal advertising (otherwise I would buy it). I probably will try Facebook ads next. Open to other advertising ideas!

You could purchase a booth / sponsorship at a retro-computing convention. You could also figure out which specific software from Mac OS 9 people are using, and participate + advertise in their hangouts (the marketing message there would be "you're set with software right now, but you could be running the same tools with less waiting-around-time on a faster machine."
