18 OS X El Capitan Tips That Every Mac User Should Know

Apple has a long history of sprinkling Easter eggs, shortcuts, and other hard-to-find tricks throughout the Mac OS. Here are a few OS X El Capitan tips that every Mac user should know.

For all that Apple prefers to tend toward the simplistic in their designs  (and this is at all levels of the company), their software can be surprisingly complex on occasion. There are little OS X El Capitan tips stuffed all over the OS, and some of them you’re likely never going to find unless someone points them out…

…which is what we’re going to do. Here are 18 of our favourite OS X El Capitan tricks, in no particular order.

Quickly add accent marks to your letters.

If you’re a recent Mac convert from Windows, you might be familiar with a little app called the Character Viewer or Character Map, known affectionately as ‘charmap’ (its file name, and also the command you might type into the Windows search box to launch it). This little application, bundled with every version of Windows, lets you easily see a map of every possible variation on the letters you might type, so if you need an é instead of an e, or an å instead of an a, you can just copy and paste it into your document.

When you need to type a letter with an accent mark or a letter more appropriately found in a non-English language, press and hold the letter on your Mac keyboard. A little pop-up dialog will appear with a selection of accented letters (they’re all examples of the letter you held down, with different accents), each one labeled with a different number. With the pop-up open, just tap the number that corresponds with the desired accent, and it’ll be inserted. You can use this in any text field.

Spotlight: not just for launching programs.

If you don’t already know it, the #1 keyboard shortcut that every Mac user should know is the one that activates Spotlight: ⌘ + Space (Command + Space). When you tap these two keys simultaneously, a floating box will appear in the middle of your screen; this is Spotlight. Its core functionality is to provide a quick launching spot for, well, everything on your Mac. You can start typing in a word and get results for apps, Mac OS X settings, even websites from your Safari history and messages in your mail.

Just use ⌘ + Space to call Spotlight forth, then start typing the units you wish to convert. Looking to see how many Canadian dollars something is? Just type in 150USD, and Spotlight will give you currency values in Canadian dollars, Japanese yen, European euros, and more – though you can explicitly convert between two money systems by using both abbreviations (150USD in JPY, etc).

It doesn’t end there; Spotlight likes all sorts of units. Whether it’s distance, volume, or temperature, Spotlight will convert it for you. You can even use it to solve simple math problems without having to start up Calculator.app.

Keep your Mac from falling asleep with a little caffeine.

This tip involves using the Mac terminal, a throwback to the days when computers never even had a graphical user interface. It’s still one of the most powerful and efficient ways to operate a computer, but it can be a little scary for people not used to working with a command line.

18 OS X El Capitan TipsTo launch, look down for a black computer display icon on your dock, or engage Spotlight and type Terminal, then hit enter. This app is called caffeinate, and it’s built into your Mac. It’s expressly designed to keep your Mac from sleeping if you don’t want it to. With terminal open, type:

caffeinate -t SECONDS &

then hit enter. Caffeinate is the name of the program, -t means time, and instead of SECONDS, enter the number of seconds you want your Mac to stay awake (hint: there are 3600 seconds in an hour), after which it’ll resume its normal sleep/wake schedule. Typing in the & after your command lets this program run in the background while you can keep using the terminal. Leaving it off will tie up your terminal window until it’s finished.

You can add a few more options (known as flags) to your caffeinate command. Using -i will prevent your computer from sleeping due to idle activity; -m prevents just the disks from sleeping while -d prevents only the display from sleeping.

Your Mac can help you remember the right word.

Ever have that problem where you remember how a word starts, but nothing seems quite right? Your Mac can help figure out what you were trying to say. Open an app and begin typing. Hit Fn+F5 together, and starting at your word, a drop-down list will appear, filled with all the words that are similar in spelling to the one you’re writing. The list can change, depending on the context of your writing. All the same, it’s a great way to help those ‘tip-of-my-tongue’ moments.

If you click on an icon in your Mac’s dock, or an a listing inside of your Spotlight search results, you’ll instantly launch the program (or if it’s a file, you’ll open the file in whatever default program is assigned to it). Sometimes, however, you just want to know where something is without having to open it up or searching all these context menus.

The key (ha!) is . Hold down your Command key and click on a program in your dock, or on a program or file that’s listed in your Spotlight results. Instead of opening up the app directly, you’ll open a new Finder window in the directory of that program or file.

AirPlay directly from the menu bar.

AirPlay is Apple’s networked audio and video protocol – it’s what lets you stream your music and videos from your iPhone or Mac to your speakers or television. But you don’t need to wait for an app like QuickTime or iTunes to load before you can get AirPlay up and running – there’s a shortcut you can access straight from the menu bar.

18 OS X El Capitan TipsLook for the AirPlay symbol – it looks a little like a flat-screen television with a big triange in front of it). Click on it, and it’ll list any devices compatible with AirPlay video – for the most part, that means Apple TVs – this icon doesn’t display if your network doesn’t have an Apple TV on it. Find the right television, click on the listing, and you’re off to the races – your whole screen will be mirrored on the display. It’s not without lag, but it’s good enough for most things, outside of gaming. You can also use it to extend your desktop display, and not just mirror – useful if you want to use your computer while displaying something else on the TV.

Change your audio output device with option.

If you need to use different audio outputs on a regular basis, you’ll soon grow tired of launching your Mac’s Preferences, drilling down into the sound features, selecting the new audio output, closing the windows, and doing it all over again when you want to switch back. There’s a better way, and it’s sitting up there on your menu bar.

18 OS X El Capitan TipsMouse up to the volume icon and click on it. You’ll see a little volume meter appear. Click anywhere to get rid of it. Now hold down your Option / Alt / ⌥ key and click the volume icon again. Instead of a volume meter, you’ll see all your audio inputs and outputs listed – just click on the one you want to switch to, and your audio source will change accordingly.

Option-click menu bar icons for more detailed information.

Related to the above tip, you can use the⌥ + click trick to get more detailed information about a number of different icons living in your menu bar. Obviously, the kind of results you get will vary depending on which icon you click. ⌥ + clicking your Wi-Fi or Bluetooth icons will get you detailed radio information, including MAC addresses and signal strength.

18 OS X El Capitan TipsUsing option with the Dropbox icon gets you a native Mac menu with quick access to preferences and your local folder, and option-clicking the three-bar Notification Center will grey it out and enable your Mac’s Do Not Disturb mode until the next morning – a good shortcut to know if you’ve got an app that’s flooding you with notifications.

Use the trackpad or mouse wheel to scroll in windows without focus.

One difference between Mac OS X and some versions of Windows is the way your Mac treats the windows you have open on your screen. In some versions of Windows, unless you click on a window on your PC, you can’t really interact with it.

On the Mac, however, you can actually scroll around in a window with switching focus (we tested this on Windows 10, and it seems to work fine there, now, too). This comes in really handy if you’re writing or taking notes in one app, and reading the web or a Word document in another. You can scroll around all you like without having to click or even stop typing

You can change volume in quarter increments.

By default, you can change the volume on your Mac to one of 16 different levels. Apple has hidden a keyboard shortcut that lets you increase that to 64 different levels, a four fold difference.

18 OS X El Capitan TipsJust hold down⌥ + Shift and tap your up or down volume key, depending on whether you want to increment or decrement your Mac’s volume. A familiar, transparent pop-up will appear, accompanied by the volume clicking noise. If you look closely, however, you’ll see that each little block goes up and down in fourths now, instead of a full block.

You can change brightness in quarter increments.

You can probably guess how this one works, but the same command above will also work for changing your brightness by quarter steps. Just hold down your Option and Shift keys, and press the appropriate button.

This command works on both your screen brightness and your keyboard backlighting, so you’ll be able to get juuuuuuust the right amount of light.

Preview almost any file with Preview and Finder.

Preview is one of the best parts of the Mac operating system, and it seems like people never talk about. It comes built into every Mac, and it lets you quick check out pictures, PDFs, text documents, audio, video, and more. There are a couple of ways to take advantage of it.

18 OS X El Capitan TipsFor previewing pictures and documents, you can usually just double-click without bothering to install any special software – basic viewing works right out of the box. An even quicker way of going through pictures and documents? Just hit the spacebar. You’ll see the picture pop up on screen in a special Finder window – this spacebar trick will work with almost any kind of media, including music and movies. If you have to look through a bunch of files, just start at the top, hit your spacebar, then use the arrow keys to sort through everything. When you’re finished, just hit the spacebar again.

Export pictures to different formats.

Your Mac comes with tools that let you export a picture to several different formats – so if you need to switch between BMPs, JPGs, TIFFs, PNGs, and so on, you don’t need to buy or download any kind of image manipulation software like Photoshop or one of its clones.

18 OS X El Capitan TipsDouble-click on the picture you want to change to open it up in Preview. In your menu bar, click on File, then in the new menu, click on Export. You’ll see a small box appear on your screen, and here you can change where the new file will be saved. A drop-down menu is toward the bottom; click on it, and there’ll be a few file types you can save between. Choose the one you need, click okay, and you’ll have a new copy of your image, in a totally different format.

Save any document to PDF.

You can save any document on your Mac to PDF, which is handy for sharing between partners, teams, and even different organizations. There are two ways to accomplish this. If it’s a file that you can open up in Preview, you can use the same steps as above. This time, click on File, and in the menu, select Export as PDF. Just pick where to save the new PDF, and you’re done.

18 OS X El Capitan TipsIf you can’t or don’t wish to open the file in Preview, you can still generate a PDF. Open the file in whichever program you used to edit it, and hit Command + P to bring up the print dialog. Some programs will generate their own print windows; Chrome, for example, puts a PDF link right in the window. For others, you might need to click something labeled Print using system dialog; this returns print control to OS X. In the system dialog, there’s a little box in the lower-left corner that says PDF. Click on it, and you’ll be able to open a PDF of your “printed” document in Preview, or have the option to simply save the PDF anywhere you like.

Easily zoom the entire screen.

Apple builds a number of accessibility features into their products, and we can take advantage of them to zoom the entire desktop. Mouse up to the menu bar, click on the Apple icon, and select System Preferences. In the preferences window, look for Accessibility. In the new window, find Zoom in the left column, and click on it.

18 OS X El Capitan TipsOn the right, you’ll see a number of features, but what we want to check is the box that reads  Use scroll gesture with modifier keys to zoom. The default trigger key is Control, but you can change it to use either Option or Command, as well. Pick your key, then close out this window (let’s say you left it as Control). To zoom in and out, just hold down Control and swipe up and down with two fingers on your trackpad, just like you scroll in a web browser. As you move your fingers up, the screen will zoom in; as you move them down, it’ll zoom back out.

Set up the corners of your screen to trigger an action or lock your Mac.

One of the lesser-known features of OS X is the ability to set up a “hot corner” in each corner of your screen. After you set them up, hot corners will execute a specific action every time you mouse into a corner. To set them up, open your Mac’s System Preferences. In the top row, you’ll find an icon labeled Desktop & Screen Saver. Click that, then look for a button that reads Hot Corners.

18 OS X El Capitan TipsThe new pop-up will have four empty boxes; there’s one for every corner. Click on one and you’ll see the options you can set: start or disable your screen saver, show your desktop or Notification Center, or just put the display to sleep. If you set your screen saver to require a login, you’ll have an easy way of locking your computer with a simple swipe of the mouse.

Set up custom keyboard shortcuts for any application.

Dive back into your settings, but this time open up Keyboard. Click on Shortcuts at the top of the window and you’ll see a list appear, neatly organized into groups on the left. Find App Shortcuts and click on it. Here’s where you can set your custom shortcut for a specific app.

18 OS X El Capitan TipsClick on the plus sign at the bottom of the window. In the new window, select the application you want to create a shortcut for using the drop-down menu. If your app isn’t listed, you might need to move it into your Applications directory. Next, enter the Menu Title of you shortcut. Menu title is the text you see in the drop-down menus for an app. Remember how we saved images to other file types a few paragraphs ago? The Menu Title of that command is Export. I chose Preview for my application, and Export… as the Menu Title. I made the shortcut easy to remember – just a ⌘E.

Now on my Mac, I can open a picture with Preview and hit ⌘E to bring up the export dialog – try it on a command you find yourself using a lot.

Your Mac stores all of your passwords, and you can take a peek if you forget.

Sometimes you’ll find yourself trying to remember a password, either for an online account or for the Wi-Fi at your buddy’s – you might have the Wi-Fi password saved, for example, but you need it to get your phone or tablet on the Wi-Fi as well. Fortunately, OS X keeps track of all your passwords for you, and saves them – encrypted – in a tool known as KeyChain Access. Start it by opening Spotlight (⌘ + Space) and typing in keychain, then hit enter.

18 OS X El Capitan TipsYou’ll see a big list of items. Fortunately, there’s a search box in the upper-right corner. Enter in the name of the website, or Wi-Fi access point and hit enter. You’ll see the list be pared down from hundreds, to just a few. Find the entry you need and double-click it. This new window has more detailed information, but what you need is to click the Show password check box. When you do, your Mac will ask you for your login password – that’s normal and a security measure. Type in your password and hit enter, and you’ll see the unencrypted password appear in an empty box.

Force quit frozen applications straight from the dock.

18 OS X El Capitan Tips

Unfortunately, I had to take a picture of the screen, as using the OS X screenshot tool makes Force Quit disappear.

Every once in a while, you’ll find yourself with a hung application, and an inability to do very much about. There’s an easy way to kill the app without invoking the Mac’s Activity Monitor. Mouse down to your dock, and right-click on the icon of the offending program. You’ll see a few options appear, like Quit. Instead of clicking on it, hold down your Option key. That Quit menu item will change, and now it reads Force Quit. With your Option key still held down, click on Force Quit, and the offending program should be killed; it might take a few seconds before you notice anything.
