I always think of myself as a big proponent of Mac apps that are as Mac-like as possible, but what does “Mac-like” really mean?

If you used a Mac computer in the '80s or '90s, you likely remember what's now called Classic Mac OS, the precursor to the OS called macOS today. You might think you would need to find an ancient Mac on Craigslist to use that operating system again, but that's not true: you can try them all in your browser right now.
