We depend on all five of these and we depend on them in concert. They are the ones that profoundly improve your work and your enjoyment of working at a Mac. Most importantly, though, these are the utilities that it would be worth buying a Mac to get. They do so much that you're unlikely to ever fully exploit them. These days, though, many utilities and each of the five we've picked here are powerhouses. It's still the case that you don't tend to use them for your main work, that they are extras that help you out. Now, though, utilities have stopped being like a single screwdriver and have become more like a whole hardware store. So a calculator was definitely a utility, arguably a basic weather app was too. You knew it was a small app, that it did one thing and that you used it alongside your regular work. Back when we first started using Macs, everybody was clear on what a utility was.
