Path 1 is recommended for beginners that are very new to using command prompts or "terminal" on the Mac. There are two paths to the intial operating system instalation and WiFI setup. You might never need it, but if you do, you’ll be glad you have it.In order to use the RPi2 with openaps development tools, the RPi2 must have an operating system installed and be set up in a very specific way. So really, there’s no reason not to install The Unarchiver. It’s the kind of tool that doesn’t get in your way, just does its job quietly and unremarkably. But frankly, that’s all The Unarchiver really needs to do. Its preferences let you choose which archiving formats it’s the default system handler for, as well as how to treat the resulting files and the original archives. It’s not a piece of software that has much in the way of user interface. In fact, I’ve never run into a file format that The Unarchiver can’t handle. Which meant downloading the multi-gig file all over again.) The Unarchiver, though, dealt with it with aplomb. (Sure enough, the first time I downloaded it, I missed this fact, and ended up with something my VM software couldn’t read. Recently I was downloading a compressed virtual machine for a project, and the instructions were adamant that the file could not be decompressed with macOS’s standard tools, since it would end up extracting the VM in the wrong format. I don’t find myself using The Unarchiver that much, but when I do, it’s critical. In addition to handling your standard ZIP files, The Unarchiver can accommodate a ton of other compression and archiving formats, like RAR, gzip, tar, and even those old StuffIt files you might have lying around. In those eventualities, I have for years turned to The Unarchiver. And for most people, that’s probably enough.īut every once in a while, I run across something for which macOS’s built-in compression capabilities aren’t quite sufficient. These days, of course, file compression is built right into macOS, with the ability to zip and unzip files directly accessible via the Finder. But I still remember all too well the heady days of the ‘90s, when downloading anything off a bulletin board or the nascent Internet meant relying on that old chestnut, StuffIt Expander, and working with. File compression! It’s not sexy, it’s not new, but it’s still something we all deal with, even in this day and age of superfast Internet connections and terabytes of storage. ![]()
