@geerlingguy Have you seen the proxy servers that let old PCs and Macs at least connect to the Internet in rudimentary ways?

I was doing pretty much exactly what you were a few days ago. Unfortunately, Apple seems to have taken down their Software Updates for Tiger and Leopard, so they need to be manually applied even if you have a proxy set up.

Still, it's important to check these old Macs to see if CityCopter One is Reporting Heavy Traffic.
