Turning the dang thing on

Okay. This is the big moment — turning on your Mac! Gaze at it longingly first, and say something cheesy, such as, “You’re the most awesome computer I’ve ever known.” If that doesn’t turn on your Mac (and it probably won’t), read on.

Apple, in its infinite wisdom, has manufactured Macs with power buttons on every conceivable surface: on the front, side, and back of the computer itself, and even on the keyboard and monitor.

So if you don’t know how to turn on your Mac, don’t feel bad; just look in the manual or booklet that came with your Mac. It’s at least one thing that the documentation always covers.

You don’t have that little booklet? Most Macs have the power button in the upper-right corner of the keyboard (notebooks) or at the back of the screen (iMacs); it usually looks like the little circle thingy you see in the margin.

Don’t bother choosing Help ⇒ Mac Help, which opens the Help Viewer program. It can’t tell you where the switch is. Although the Help program is good for finding out a lot of things, the location of the power button isn’t among them. If you haven’t found the switch and turned on the Mac, of course, you can’t access Help anyway. (D’oh!)

Launch the iBooks app and search the iBooks Store for the name of your Mac plus the word Essentials (for example, “MacBook Essentials,” “iMac Essentials,” or “MacBook Pro Essentials”). Click the Only Show Free Titles check box near the upper-right corner of the iBooks window, and grab the free Essentials e-book with your Mac’s name, by Apple. At around 100 pages, this booklet isn’t in any way comprehensive, but it does include information you won’t find elsewhere, including where to find the power button on your particular Mac.

Shutting down properly

Turning off the power without shutting down your Mac properly is one of the worst things you can do to your poor Mac. Shutting down your Mac improperly can really screw up your hard or solid-state drive, scramble the contents of your most important files, or both.

If a thunderstorm is rumbling nearby, or you’re unfortunate enough to have rolling blackouts where you live, you may really want to shut down your Mac and unplug it from the wall. (See the next section, where I briefly discuss lightning and your Mac.) If it’s a laptop, you can just disconnect it from its charging cable and continue using it if you like.

To turn off your Mac, always use the Shut Down command from the menu or shut down in one of these kind and gentle ways:

• Press the power button for approximately two seconds and then click the Shut Down button in the Are You Sure You Want to Shut Down Your Computer Now? dialog.

• On keyboards that don’t have a power key, press Control+Eject instead, and then click the Shut Down button that appears in the Are You Sure You Want to Shut Down Your Computer Now? dialog.

  You can use a handy keyboard shortcut when the Shut Down button (or any button, for that matter) is highlighted in blue and pulsating slightly. Pressing the Return key is the same as clicking whichever button is highlighted.

The Are You Sure You Want to Shut Down Your Computer Now? dialog sports a check box option: Reopen Windows When Logging Back In. If you select this check box, your Mac will start back up with the same windows (and applications) that were open when you shut down or restarted. I think that’s pretty darn sweet, but you can clear the check box and disable this option if that’s not what you want!

Most Mac users have been forced to shut down improperly more than once without anything horrible happening, of course — but don’t be lulled into a false sense of security. Break the rules one time too many (or under the wrong circumstances), and your most important files could be toast. The only time you should turn off your Mac without shutting down properly is when your screen is completely frozen or when your system crashed due to a kernel panic and you’ve already tried everything else. (See Chapter 23 for a list of those “everything elses.”) A stubborn crash doesn’t happen often — and less often under macOS (formerly OS X) than ever before — but when it does, forcing your Mac to turn off and then back on might be the only solution.

A few things you should definitely not do with your Mac

In this section, I cover the bad stuff that can happen to your computer if you do the wrong things with it. If something bad has already happened to you … . I know, I’m beginning to sound like a broken record, but see Chapter 23.

• Don’t unplug your Mac when it’s turned on. Very bad things can happen, such as having your OS break. See the preceding section, where I discuss shutting down your system properly.

  Note that this warning doesn’t apply to laptops as long as their battery is at least partially charged. As long as there’s enough juice in the battery to power your Mac, you can connect and disconnect its power adapter to your heart’s content.

• Don’t use your Mac when lightning is near. Here’s a simple life equation for you: Mac + lightning = dead Mac. ’Nuff said. Oh, and don’t place much faith in inexpensive surge protectors. A good jolt of lightning will fry the surge protector and everything plugged into it, including computers, modems, printers, and hubs. Some surge protectors can withstand most lightning strikes, but those warriors aren’t the cheapies that you buy at your local computer emporium. Unplugging your Mac from the wall during electrical storms is safer and less expensive. (Don’t forget to unplug your external modem, network hubs, printers, and other hardware that plugs into the wall as well; lightning can fry them, too.)

  For laptops, disconnect the power adapter and all other cables because whatever those cables are connected to could fry — and fry your laptop right along with it. After you do that, you can use your laptop during a storm if you care to. Just make sure that it’s 100 percent wireless and cableless when you do.

• Don’t jostle, bump, shake, kick, throw, dribble, or punt your Mac, especially while it’s running. Many older Macs contain a hard drive that spins at 5,200 revolutions per minute (rpm) or more. A jolt to a hard drive while it’s reading or writing a file can cause the head to crash into the disk, which can render many — or all — files on it unrecoverable. Ouch!

  Don’t think you’re exempt if your Mac uses a solid-state drive with no moving parts. A good bump to your Mac could damage other components. Treat your Mac like it’s a carton of eggs, and you’ll never be sorry.

• Don’t forget to back up your data! If the files on your hard drive mean anything to you, you must back up. Not maybe. Must. Even if your most important file is your last saved game of Bejeweled, you still need to back up your files. Fortunately, High Sierra includes an awesome backup utility called Time Machine. (Unfortunately, you need either an external hard drive or an Apple Time Capsule device to take advantage of it.) So I beg you: Please read Chapter 21 now, and find out how to back up before something horrible happens to your valuable data!

  I strongly recommend that you read Chapter 21 sooner rather than later — preferably before you do any significant work on your Mac. Dr. Mac says, “There are only two kinds of Mac users: Those who have lost data and those who will.” Which kind do you want to be?

• Don’t kiss your monitor while wearing stuff on your lips. For obvious reasons! Use a clean, soft microfiber cloth and OmniCleanz display cleaning solution (I love the stuff, made by RadTech; www.radtech.us) to clean your display.

  Definitely do not use household window cleaners or paper towels. Either one can harm your display. Use a soft clean cloth (preferably microfiber), and if you’re going to use a cleaner, make sure it’s specifically designed not to harm computer displays. Finally, spray the cleaner on the cloth, not on the screen.

Point-and-click boot camp

Are you new to the Mac? Just figuring out how to move the mouse around? Now is a good time to go over some fundamental stuff that you need to know for just about everything you’ll be doing on the Mac. Spend a few minutes reading this section, and soon you’ll be clicking, double-clicking, pressing, and pointing all over the place. If you think you have the whole mousing thing pretty much figured out, feel free to skip this section. I’ll catch you on the other side.

Still with me? Good. Now for some basic terminology:

• Point: Before you can click or press anything, you have to point to it. Place your hand on your mouse, and move it so that the cursor arrow is over the object you want — such as on top of an icon or a button.

  If you’re using a trackpad, slide your finger lightly across the pad until the cursor arrow is over the object you want.

• Click: Also called single click. Use your index finger to push the mouse button (or the left mouse button if your mouse has more than one) all the way down and then let go so that the button (usually) produces a satisfying clicking sound. (If you have one of the optical Apple Pro mice, you push the whole thing down to click.) Use a single click to highlight an icon, press a button, or activate a check box or window.

  In other words, first you point and then you click — point and click, in computer lingo.

  If you’re using a trackpad, press down on it to click.

• Double-click: Click twice in rapid succession. With a little practice, you can perfect this technique in no time. Use a double-click to open a folder or to launch a file or application.

  Trackpad users: Press down on the pad two times in rapid succession.

• Control-click: Hold down the Control key while single-clicking. (Also called secondary-click or right-click.)

  Trackpad users can either hold down the Control key while pressing down on the pad with one finger, or tap the trackpad with two fingers without holding down the Control key.

  If tapping your trackpad with two fingers didn’t bring up the little menu, check your Trackpad System Preferences pane (see Chapter 5).

  Control-clicking — the same as right-clicking on a Windows system — displays a menu (called a contextual or shortcut menu). In fact, if you’re blessed with a two-or-more-button mouse (such as the Apple Magic Mouse), you can right-click and avoid having to hold down the Control key. (You may have to enable this feature in the Mouse System Preferences pane.)

• Drag: Dragging something usually means you have to click it first and hold down the mouse or trackpad button. Then you move the mouse on your desk or mouse pad (or your finger on the trackpad) so that the cursor and whatever you select moves across the screen. The combination of holding down the button and dragging the mouse is usually referred to as clicking and dragging.
• Wiggle (or jiggle): This welcome improvement, introduced in El Capitan (and terrific if I do say so myself) is awesome when you lose track of the pointer on your screen. Just wiggle your mouse back and forth (or jiggle your finger back and forth on the trackpad) for a few seconds and the pointer will magically get much bigger, making it easier to see on the screen. And, of course, when you stop wiggling or jiggling, the pointer returns to its normal size.
• Choosing an item from a menu: To get to macOS menu commands, you must first open a menu and then choose the option you want. Point at the name of the menu you want with your cursor, press the mouse button, and then drag downward until you select the command you want. When the command is highlighted, finish selecting by letting go of the mouse button.

If you’re a longtime Mac user, you probably hold down the mouse button the whole time between clicking the name of the menu and selecting the command you want. You can still do it that way, but you can also click the menu name to open it, release the mouse button, point at the item you want to select, and then click again. In other words, macOS menus stay open after you click their names, even if you’re not holding down the mouse button. After you click a menu’s name to open it, you can even type the first letter (or letters) of the item to select it and then execute that item by pressing the spacebar or the Return key. Furthermore, menus remain open until you click something else.

Go ahead and give it a try … I’ll wait.

The terms given in the preceding list apply to all Mac laptop, desktop, and tower systems. If you use a MacBook, MacBook Pro, MacBook Air, or Apple Magic Trackpad, however, you'll want to add to your lexicon a few more terms — such as tap, swipe, rotate, pinch, and spread. You can read all about them in Chapters 2 and 11.
