Ways to use your Mac server
I've been working with Mac hosting for about thirteen years. I tell people about using a Mac mini as a server and they just love the idea of it. There are a lot of great hosting options out there these days, but it's nice to work with a server where the OS is familiar and you know you control the whole stack of hardware and software. Our base Mac mini subscription starts at just $49/mo (that includes the server) so it's much easier to get started.
Five years ago today, I wrote a post about ways you might use a Mac server. I've decided to update that list and add some new ones that have come along in the last little while. It's a mix of Mac apps, open source projects, and iOS tools. Now when you say to yourself "I'd love to try a Mac server but I just don't know what I'd do with it" then you can take a look at this list. (Have more suggestions? Add them here.)
