Seven Handy Mac Tricks You Might Not Know

macOS, the operating system that runs on Apple's Macs, has tons of hidden shortcuts, keyboard commands, and features that have gone under the radar. In our latest video over on our YouTube channel, we dug deep into macOS and came up with a list of useful but lesser known tips and tricks.

You might think you know everything there is to know about the Mac, but we bet there's something new here you've never come across or have forgotten over time, so make sure to check out our video.

  • Continuity Camera - In macOS Mojave, Apple introduced a feature that lets you take a photo on an iPhone or iPad and have it ported over to the Mac into the document or app of your choosing. To get to Continuity Camera in any app where it's supported, go to Edit > Insert From Your iPhone or ‌iPad‌. From there, choose "Take Photo" or "Scan Document," and it will automatically activate the camera on your iOS device so you can snap a quick photo. You can also right click in most documents to bring up a menu with the option.
  • Password Protect a Folder - Your Mac is protected by a password, but you can add an extra layer of security by password protecting any folder. To do it, open up Disk Utility, select "File" from the menu, choose "New Image" and then "Image from Folder." From there, select the folder you want to protect and create a password. Delete the original folder, and you'll need to enter a password when opening the new folder.
  • Custom Lock Screen Message - There's an option in macOS to create a custom message that shows up on the Lock screen, which is useful if you misplace your Mac because you can put in a phone number and an email address that people will see right when it's opened up. To get to it, go to System Preferences > Security & Privacy > General > Set Lock Message.
  • Emoji Quick Access - It can be a chore to add emojis to documents, texts, and social media on macOS going through the menu insert options, but there's a keyboard command that will bring up the macOS emoji selector interface in any app. Just press Control, Command, and Space Bar all at once.
  • WiFi Passwords in Keychain - Want to find a lost password for a WiFi network you've connected to before? It's stored right on your Mac in Keychain. Open up Keychain Access, choose System, and locate the WiFi name you're looking for. Right click on it (or double click), choose "Get Info," and then select "Show Password."
  • Copy Paste Screenshots - You can take and share a screenshot without cluttering up your desktop using the hidden screenshot copy paste feature. Hold Command + Control + Shift + 4, select what you want to screenshot, and it's copied to your clipboard. From there, you can paste it within any app, and there's no screenshot on your desktop when you're done.
  • Messages Screen Sharing - Need to help a parent or a friend with an issue on the Mac? You can use Messages to access their screen to make it easier. Just open up Messages, select the name of the person you want to help, and then click on "Details." Click on the screen sharing icon to connect. You can also click on "Buddies" at the top to get more screen sharing options.

Here is a shortcut I recently learned that blew my mind. Guess it started with macOS Sierra:

command + shift + .

This will toggle show/hide hidden files in the Finder. So much easier than using command line or a utility app.

Small detail on the screen shot feature:

You can start the capture without holding control and still will be able route it to the clipboard by pressing/holding control once you press the shutter/let go of the selection rectangle.

The clipboard feature also works with full screen captures (cmd-ctrl-shift-3), but there you have no delay and actually have to start the command with holding the control at the same time.

Also, cmd-shift-5 now brings up a neat capturing dialog in Mojave.

A few tips people may find useful, if you don't already know them. Hopefully we all know that Command + tab shows the open applications, and (while keeping your finger on command) using tab or left and right arrows to move between the applications. What's not so obvious is Apple added a number of other uses for this.
1 - while tabbing to an app you can quit the app by pressing Q, you can go through and quit every app if you want without going to the app. It's not a force quit, and you'll be asked if something needs saving. Similarly pressing H will hide a specific App.
2 - you can drop a file on the app icons to open with a specific app, if it can.
3 - The really handy one, which I use all the time, is when tabbing to a specific app press the up or down arrow key, at which point all the open windows in that app will be shown. If a window is in the dock it's a thumbnail at the bottom of the screen. Pick a window, and that window alone comes to the top. I usually have lots of windows open, so if I want to reference a window in another app, but going to the app brings all it's open windows to the top, this method only brings the one you want, not covering up the window you're working on.

Messages screen sharing would be great if it worked between iOS devices!! Would really help when trying to help someone figure out an issue on their iOS device.
