OS9Map is a an OpenStreetMap browser for Mac OS 9, last updated 24 years ago: three years before the volunteer-maintained mapping service was even founded. It requires a PowerPC processor, an internet connection, and 16 megabytes of RAM.
The lucky few to have a whopping 32 megabytes, though, will have the best experience of the app's smooth-scrolling canvas and search features.
Search for landmarks and addresses, and save the places you care about as bookmarks for next time.
Creator yllan also made a Bluesky client for Mac OS 9, and one for Mastodon too.
I came back to finish what that kid started. OS9Map, PlatinumSky, and ClassicNet are native Mac OS 9 apps that put those PowerPC machines back on the modern internet — real TLS, real web services, no proxies, no cheating. Just the Toolbox, a cross-compiler, and a lot of stubbornness.
It's the dream I had at twelve, built with the patience I didn't have at twelve.
