There are a handful of apps that I have to have on every Mac I use, or things quickly start to get annoying. Launchbar is one. Dropbox is another, and TextExpander is one more. TextExpander is sold as a way to expand a short string of text into a longer string of text, so I can just type, say, “aadd” and my address magically appears. I use it all day long on both Mac and iOS for adding Markdown and HTML code to my Cult of Mac posts, and even to the the name Cult of Mac (shortcut: ccom).
But there’s a lot more in there, as this example will show. BEcause TextExpander can run scripts, it can query all kinds of neat stuff — including finding out about your Mac.
