Apps, even after being removed from the Launchpad or Applications sidebar in Finder, do leave preferences and other files scattered around. Where are they, typically, and how does one find them?
I discovered that Xcode includes a diff tool called FileMerge. Where is it and how do you launch it?
I just bought a MacBook Pro! Prior to this, I've only been exposed to Windows and a smattering of UNIX/Linux... until now. What really struck me was the price! Total sticker shock, and that was before Apple raised prices on 14 Oct 2015!
I, like many other iPhone users, turn on AssistiveTouch so that I don't have to press the Home button. Historically, this button has been quick to fail, so using the on-screen icon will save some wear-and-tear. And with iOS 9, AssitiveTouch has become customizable! Shocking (for Apple, not much is customizable)!

A short list of free tools I find useful for blogging and web development! Includes Microsoft Visual Studio Code, ImageOptim, ForkLift 2 and Commander One.
Forget the complex or manual steps, or costly tools to get screen shots scaled down from a retina display.

Best of all, it does not require paid software or Automator.
Some tweaks to my OS X shell (Terminal.app) that I've found useful.
