Welcome to Messages

Messages does seven things very well:

• Instant messaging. Instant messaging combines the privacy of email and the immediacy of the phone. You type messages in a chat window, and your friends type back to you in real time.

  You can keep your text messages, too. They’re not locked onto your phone, like regular text messages, and they don’t scroll away forever, like regular text messages. You can archive them, search them, copy and paste them, print them, forward them, and so on.

• Unified chat/text messages with phones (iMessages). This is huge. If you and your conversation partner both have iCloud accounts, then you both can move freely from phone to tablet to Mac. Your conversation appears in real time on all your gadgets simultaneously. If you started texting someone on the train home, you can sit down at your Mac and open Messages—and pick up right where you left off.

  The messages, which Apple calls iMessages, are a lot more flexible than regular text messages. They can be much longer than 160 characters. They can include photos, movies, or other kinds of files. They give you feedback that lets you know when a message has arrived on the recipient’s gadget.

  And they don’t count as text messages. They’re routed through the internet rather than the cellphone voice network. As far as your cellphone company is concerned, you’re not texting at all, and therefore you don’t have to pay for a texting plan.

• Send text messages. If you have an iPhone, you can also exchange text messages with any cellphone—from Messages, while seated at your Mac. That’s a mind-bending violation of the usual rules that confine text messages to cellphones only.

• Send audio clips. Instead of just typing a line or two to somebody, you can speak it. That short recording winds up on the other person’s Mac, iPhone, or iPad. It’s like leaving a voicemail.

• Free videoconferencing. Messages can auto-open FaceTime, for those situations when having a face-to-face video chat (or a high-quality voice call) is more efficient than typing.

• File transfers. Got an album of high-quality photos or a giant presentation file that’s too big to send by email? Forget about using some online file-transfer service or networked server; you can drag that monster file directly to your buddy’s Mac, through Messages, for a direct machine-to-machine transfer. (It lands in the other Mac’s Downloads folder.)

• Screen sharing. Next time your parents or neighbors are throwing themselves upon your mercy for tech support, remember this: Messages lets you see their screen, and even control it, from across the internet. Or you can volunteer your own screen for sharing, so you can demonstrate things to them.

When you open Messages for the first time, you’re invited to sign into (or sign up for) your iCloud or Apple account. Take the opportunity to set this up; you’ll be glad you did. (You may have to authenticate your account—prove it’s really you—by entering a six-digit code that Apple sends to all the other gadgets on your Apple account, like your iPhone.)

Let the Chat Begin

If you’ve ever corresponded with someone in Messages before, you see that person’s name in the left-side list of conversations, as shown in Figure 19-1. (Or, if you’ve got a lot of conversations listed there, you can use the search box above the list to find that person.) Click the name and then start typing into the message box. The “conversation” with that person continues, even if the last exchange was months or years ago.

To start chatting with someone you’ve never corresponded with before, click the Compose button () next to the search box. The To field appears. As you type your buddy’s name into it, Messages sprouts a list of matching names from your Contacts.

Some of them probably feature a blue speech bubble (). Those are people with iCloud accounts—with whom you can exchange iMessages, described next.

You can also click the button to get a pop-up version of your Contacts, complete with a search bar at the top.

Once you’ve selected your lucky conversation partner(s), just type what you want to say into the message box at the bottom of the window. As you correspond, the conversation appears in speech bubbles, scrolling up like a screenplay, making it easy to identify who said what—and to scroll back up to see what someone said earlier. (See Figure 19-1.)

Figure 19-1. Messages keeps tabs on your various simultaneous conversations—literally. Click the different tabs to switch chats. Double-click one to open it into its own window, without the tabs taking up space.

If someone invites you to chat, a notification appears in the top-right corner of your screen. If you point to it in time, you get a Reply button; see Figure 19-2.

If you click the notification instead, Messages opens automatically; click in the message box at the bottom and type your witty reply.

Figure 19-2. When someone messages you, a bubble like this appears in the top-right corner of your screen. If you point to it before it vanishes, the Reply button appears, as shown here.
If you click it, you can type a quick response right there in the notification window (bottom), without having to fire up Messages at all.

iMessages

If the box where you type says “iMessage” in faint lettering, then you’re about to chat with a fellow iCloud member—and you’ll be sending iMessages. (Another clue: Your speech bubbles appear in blue, rather than green.) And you’ll enjoy a long list of extra benefits as you chat (as compared with, for example, standard cellphone text messages).

For example:

• Fancier, longer posts. You can type outrageously long messages (unlike standard text messages, which are limited to 160 characters). And iMessages are unlimited and free.

• Dressier chats. You can use fonts and colors in your conversation.

• Multigadget simulcasting. If you have multiple Apple gadgets, and you’ve set up your iMessages email address or phone number identically in the Settings or System Preferences of each one, then your conversation appears simultaneously on all the gadgets. (“Simultaneously,” however, is relative. If one of your devices has been offline for some time while you’ve been chatting on the other, it may take a few minutes to catch up. You’ll see all the iMessages it missed pouring in.)

  That’s extremely useful, because it means you can (for example) start texting on your phone when you’re out and about and pick up seamlessly on your Mac when you get home, enjoying the real keyboard and big screen.

• Link previews. When you send a web address in an iMessage, it appears on the recipient’s screen as a little preview of the actual web page, for convenient identification. And if you send a video link, your buddy can play it right there in Messages, without having to lurch off to a web browser! (Click once to make the tiny video start playing; click a second time to make it stop. There’s no scroll bar.)

  Tip

  And what if you want to lurch off to a web browser—for example, because you want to see that YouTube video bigger than a Wheat Thin? In that case, click the label beneath the video thumbnail.

• Built-in suspense. Whenever the other guy is typing, you see “…” in his balloon, so you know he’s working on a response and not just ignoring you.

  Tip

  The ellipsis dots appear as soon as the other guy starts typing—and remain on your screen for 60 seconds, even if he stopped typing a long time ago. Conversely, they disappear from your screen after 60 seconds, even if he’s still typing! Often you’ll see the dots disappear shortly before you get a huge, long paragraph—because the other guy took longer than 60 seconds to write it.

• Insta-file sending. You can drag photos, movies, or other files (up to 100 megabytes!) into the typing box. They’ll show up on the other guy’s Mac, phone, or tablet just fine.

• Easy switching to phone or video. If you find that typing is losing too much emotional nuance, and you are signed into FaceTime on your Mac, you can jump into a voice call or video call at any point. For voice calls, you can choose either a FaceTime Audio call or a phone call; for video, the FaceTime app opens, and you can proceed as described in “DVD Player”.

  To jump into a voice call, click Details (top right); on the panel, click ; click FaceTime Audio. (Or, if you have an iPhone, you can click the person’s phone number and make an actual phone call.) Once your invitation is accepted, you can begin speaking to each other. The bars of the sound-level meter let you know that the microphone is working.

  To switch to a video call, click Details at the upper right of the Messages window, and then click . A FaceTime call begins right away.

• Tapbacks. How many trillions of times a day do people respond to texts with repetitive reactions like “LOL” and “Awww” and “!!!!!”? Many. It’s how you demonstrate to your chat partner that you appreciate the import of her text.

  But if you and your buddy are both using iOS 10 or macOS Sierra or later, you’ve now got a quicker, less cluttery, more visual way to indicate those sorts of standard emotional reactions: what Apple calls tapbacks. Figure 19-3 shows you the ropes. Tapbacks take the form of six reaction icons: Heart, Thumbs Up, Thumbs Down, Ha Ha, Exclamation Points, and Question Mark. When you choose one, it appears instantly on your screen and your buddy’s.

  

  Figure 19-3. In Messages, right-click or two-finger click the bubble you’re reacting to. (It can even be something you’ve said.) From the shortcut menu, choose Tapback (top). Now you’re offered a choice of six reaction icons (middle). Click one to stamp it on the text message (bottom). It appears instantly on your screen and your buddy’s.

  Tip

  What’s cool is that you can change your tapback icon later, if new information affects your reaction; just right-click or two-finger click again, and choose Tapback again, to bring up the same palette.

• Incoming fanciness. Messages on the Mac doesn’t let you express yourself in all the ways Messages on an iPhone does in iOS 10 and later. But it can receive some of the cool effects that your iOS friends send you, like handwriting, invisible ink, and stickers; see Figure 19-4.

  

  Figure 19-4. Among the cool Messages effects (from top): invisible ink (text that doesn’t appear until you move your mouse across it—useful when the sender doesn’t want to embarrass you), handwriting, and stickers (still or animated images your pal has dragged onto a message). You can’t create these effects on the Mac, but you can receive them when they’re sent by iPhones and iPads.

• Big, plentiful emoji. You can use the emoji pop-up menu (at the right end of the typing box) to insert emoticons and smileys.

  If you know the correct codes to produce the emoji you want—typing :) produces a yellow happy face, for example, and <3 produces a red heart—you can save time by typing them instead of using the pop-up menu. Messages converts them into smiley or heart icons on the fly, as soon as you send your reply.

  The emoji you transmit appear enormous—at three times their usual size—if you’ve typed three of them or fewer on a single line. (If, that is, your recipient is using an Apple device running iOS 10 or Sierra or later versions.)

  Tip

  If you have a Touch Bar (“The Complicated Story of the Function Keys”), you’ll find it much easier to enter emoji by tapping. Touch the button to see a row of frequently used emoji, any of which you can insert by tapping. Or you can tap the button to see a row of icons representing the other categories of emoji available to your fingertip.

• Real-time feedback. The tiny word “Delivered” appears beneath any message you send to let you know that your recipient’s gadget has received it. If the recipient has turned on “Send read receipts” (in Messages → Preferences → iMessage), you’ll even see the word “Read” to let you know that the person has actually seen the message.

  Tip

  What about you? Do you want the other guy to know when you’ve seen his texts? You can turn “Send read receipts” on or off in Preferences, of course. But you can also turn it on or off for an individual buddy. You might want your primary love interests to know when you’ve seen their texts, for example, but you might not think your co-workers need to know.

  Within a chat, click Details at the top right. And there it is: a Send Read Receipts checkbox for just this conversation partner (visible in Figure 19-5).

• Individual attachments. This one’s really cool; see Figure 19-5.

  

  Figure 19-5. If you click the Details button at the top right of the window, you get to see a mosaic of every attachment you’ve ever exchanged with this correspondent—files, photos, videos, whatever. Double-click one to open it. No more scrolling back through thousands of pages of typed text to find something you remember getting!
  This Details panel also gets you access to buttons that begin screen sharing, phone calling, or video chatting with this lucky individual.

• Type size. Use the commands in the View menu to make all type larger or smaller—or just press -plus or -minus.

• Sound clips. A special button appears whenever you’re exchanging iMessages, just to the right of the typing box. It lets you quickly shoot over an audio bite as easily as you’d type something.

  Just click the , say what you want to say, and then click the square Stop button. Now you can Cancel it or Send it.

  What you said is instantly transmitted to your buddy as an audio recording.

  If the recipient has an iPhone with iOS 8 or later, he can listen just by lifting the phone to his head. And then, get this: To reply, he doesn’t have to touch anything or look at the screen. He just holds the phone to his head again and speaks! Once he lowers the phone, his recording shoots back to you.

  Sometimes, an audio recording is just better than a typed message, especially when music, children, animals, or a lot of emotion in your voice are involved.

  Tip

  Audio eats up a lot more space than text. If you do a lot of audio messaging, then, over time, those audio snippets can fill up your storage. That’s why Messages comes set to delete each audio message two minutes after you send it—unless you click Keep within that window of time.

• Location mapping. If you’re chatting with an iPhone owner, that same Details panel might reveal a map that shows her current location in the world. (The map appears only if she’s turned on “Share my location” on her phone.)

Messages blurs the lines between text messages, chats, and email. And it gives birth to this frequently asked question: “Are you on the phone or the Mac?” Now there’s no way to know.

Group Chats

There’s nothing to stop you from inviting several people to a single chat. Just click the Compose button () as usual. Enter the desired chat partners’ names one at a time in the To field, pressing Return or adding a space after each one.

Tip

If you’ve created a group in Contacts, you can also just enter the group’s name. Everybody in it is instantly part of the chat.

Now you’ve got yourself a party line. Anything anyone types, everybody sees. Be careful what you say, won’t you?

Many of the group-chat features are hiding in the panel that appears when you click Details at top right (Figure 19-6).

Figure 19-6. If you click where it says “Add a group name,” you can type a new name. That should make it easier to identify this conversation later in the list of chats at the left side of the window. (The Details button doesn’t appear until somebody has actually said something in this chat.)
You can also add participants, even after the group chat is underway; click Add Member.
Do Not Disturb means that new texts from this group won’t trigger notifications on your Mac. And if the bickering becomes more than you can stand, you can excuse yourself and leave the chat by clicking “Leave this Conversation.”

Sharing Your Screen

As you’ve seen already, Messages lets you share your thoughts, your voice, and your image. And now, for its next trick, it lets you share…your computer.

Messages’ screen-sharing feature is a close relative of the network screen-sharing feature described in “Screen Sharing”. It lets you not only see what’s on a faraway buddy’s screen, but also control it, taking command of the distant mouse and keyboard. (You can share your screen with the other guy, too.)

You can open folders, create and edit documents, and copy files on the shared Mac screen. Sharing a screen makes collaborating as easy as working side by side around the same Mac, except now you can be sitting in San Francisco while your buddy is banging it out in Boston.

And if you’re the family tech-support specialist—but the family lives all over the country—screen sharing makes troubleshooting infinitely easier. You can now jump on your mom’s shared Mac and figure out why the formatting went wacky in her Word document, without her having to attempt to explain it to you over the phone. (“And then the little thingy disappeared and the doohickey got scrambled…”)

To make Messages’ screen sharing work, you and your buddy must both be using an iCloud account, or be on the same Wi-Fi network (the Mac’s Bonjour feature will make your Macs show up on each other’s screens).

iCloud Screen Sharing

From within an iMessages conversation (that is, a chat between two iCloud members), you can share your whole Mac screen, right there in Messages. Both people have to be using Macs running Yosemite or later (not an iPhone, and not an older Mac).

There are other ways to share screens, of course (“Screen Sharing”)—but this is by far the easiest to set up.

Figure 19-7. Top: You either send or receive an invitation to start sharing your screen, but make sure you know with whom you’re dealing before accepting the offer and starting the sharing process.
Bottom: When you’re sharing someone else’s screen, you have the option to click back and forth between the two Mac screens.
You can move the cursor, click things, and even highlight text on the other guy’s screen. That’s great for explaining to someone, via remote control, how to perform some task.

Once a typed chat is underway, click Details (top right), and then click (see Figure 19-7, top). If that icon is dimmed gray instead of blue, it’s because the other person isn’t using a Yosemite-or-later Mac.

The icon sprouts two choices: Invite to Share My Screen (meaning the other guy sees your screen) and Ask to Share Screen (you’re going to see his screen). Click the one you want.

He receives an invitation. When he clicks Accept, the sharing is underway. He sees your screen on his Mac, or vice versa, as though some freaky cosmic wormhole has opened up.

Once the screen sharing is going, a new menu appears at the top of your screen. It offers options like these:

• Allow [other guy] to control my screen. He can operate your mouse and keyboard—from his Mac, thousands of miles away.

• Mute Audio. During a screen share, Messages automatically turns on audio chatting, so you can explain stuff to each other. Mute Audio mutes the audio.

• Pause Screen Sharing is like drawing a privacy curtain when you want to duck into your email program to read something. The other guy sees only a “Paused” screen until you unpause.

• End Screen Sharing. You guessed it.
