macOS Sierra For Dummies. Bob LeVitusЧитать онлайн книгу.

(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 if 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, 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 cloth and/or 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 – like 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 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 by tapping 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 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 Preference 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, there are a few more terms – such as tap, swipe, rotate, pinch, and spread – you’ll want to add to your lexicon. You can read all about them in full and loving detail in Chapter 4.

Not Just a Beatles Movie: Help and the Help Menu

One of the best features about all Macs is the excellent built-in help, and macOS Sierra doesn’t cheat you on that legacy: This system has online help in abundance. When you have a question about how to do something, the Help Center is the first place you should
