Move MacOS Dock between monitors

When using multiple monitors on my Macs I would do this by mistake and thought it was some weird bug 🙂 Turns out, if you pull down your mouse at the bottom of the screen, this moves the Dock to that screen.

Useful when you use multiple monitors, annoying if you do it by accident and don’t know the feature exists 🙂

Screenshot features in Mac OS X and MacOS

10.13 High Sierra and earlier : Use key shortcuts (see below) or Grab.app (see here)

11.14 Mojave and after: Snapshot.app (more info here):

  • Similar to Grab but after you’ve taken the snapshot it allows you to annotate/markup the screenshot, and then you can either copy and paste from there or save as a file.
  • Additionally in Screenshot, it remembers the position on screen of an area screenshot so you can easily take repeated screenshots from the same portion of your screen.

Key shortcuts in all Mac OS X / MacOS versions (see here)

Shift + Cmd + 3 : captures whole screen

Shift + Cmd + 4 : starts a region screenshot, select a region of the screen

  • before 10.14 Mojave, saves a .png to your desktop
  • 10.14 Mojave and after – opens screenshot in the Screenshot editor app

Random useful MacOS shortcut keys

Finder shortcuts:

Cmd-down – navigate into folder (down)

Cmd-up – navigate up from current folder

Spacebar – preview a file

Shift-Cmd . – toggles display of hidden files

When using multiple monitors, if you pull the mouse cursor down on a screen you can move the Dock to that monitor.
