The feature Apple is promoting most heavily with macOS 10.14 Mojave is Dark mode, which the company advertises as “a dramatic new look that helps you focus on your work… as toolbars and menus recede into the background.” Let’s look at what Apple has done with Dark mode, after which you’ll have a better idea of what to think about while trying it.

Enable Dark Mode

First, to turn Dark mode on, go to System Preferences > General and click the Dark thumbnail to the right of Appearance. Mojave immediately switches to Dark mode, turning light backgrounds dark and swapping the text color from dark to light.

While you’re in System Preferences, click over to the Desktop & Screen Saver preference pane. If you scroll down in the Desktop Pictures list, you’ll discover a bunch of new wallpapers that blend well with Dark mode.

Dark Mode Support and Controls

You’ll notice that the color change takes place instantly not just in the Finder, but also in any apps that support Dark mode. Most of Apple’s apps support Dark mode and third-party developers are rapidly adding support to their apps as well. However, Dark mode requires explicit support from apps, so older apps that aren’t being updated will maintain their standard dark-on-light color schemes.

Some apps, such as Maps and Mail, give you additional options that change just how dark they get. In Maps, choose View > Use Dark Map to toggle between a dark map style and the familiar map style that mimics a paper map. Similarly, in Mail, go to Mail > Preferences > Viewing and deselect “Use dark backgrounds for messages” to return to a white background.

If you generally like Dark mode but have trouble reading light text on a dark background due to the reduced contrast, you may be able to choose a different font or style in the app’s preferences that makes the text more readable. Apps like Mail give you a fair amount of that sort of control.

For even more control over contrast, open System Preferences > Accessibility > Display. There you’ll find a Display Contrast slider that lets you make text lighter and backgrounds darker. You can also select Reduce Transparency to make it so items like the Dock and menu bar are solid colors, rather than allowing the background to bleed through. To separate dark and light further, select Increase Contrast, which increases the brightness of divider lines as well.

The Dark Side of Dark Mode

Contrast is necessary for pulling out fine details, but too much contrast can be uncomfortable or even painful—think about how you feel when someone turns on a bright light in a previously dark room. For visual comfort, it’s usually best to match your screen with the lighting of your surroundings. That’s why people who often work at night or with the window blinds down like dark modes—a bright screen seems brighter in a dimly lit room. That’s the theory behind the traditional dark text on a light background too, since the room will be quite light during the day.

So Dark mode can run into two problems. First is that using it during the day or in a brightly lit room may create an uncomfortable contrast between the screen and its surroundings. Controlling your room lighting can eliminate this as an issue. Second and more troubling, even apps that support Dark mode may have large content areas that are bright white, creating a strong contrast between the content area and the rest of the app. Many Web sites in Safari have this effect, as do documents in apps like Pages and Numbers. There’s no way around this scenario.

Even if Dark mode isn’t perfect, it’s worth a try if you have trouble looking at bright screens. Regardless, if it goes too far for you, one of the new dark wallpapers may be easier on your eyes. While most people aren’t overly light sensitive, a non-trivial percentage of the population is, particularly those who suffer from migraines or who have endured concussions, and those with a variety of ocular conditions. And if you’re on the other end of the spectrum—if Dark mode looks dirty and is hard to read—just stick with the traditional Light mode.

Do you frequently reach for your iPhone for a quick check of Facebook or Messages? It’s all too easy to let social media, the latest hot game, or even your work email intrude on your real life. If you’re uncomfortable with how much—and when—you use your iPhone or iPad, iOS 12’s new Screen Time feature can help you limit your usage in two ways, by time of day and by time spent in an app.

(Screen Time can help you monitor and limit your children’s iOS usage too. This article focuses on setting it up for yourself; we’ll examine Screen Time parental controls another time.)

Get Started with Screen Time

To enable Screen Time, go to Settings > Screen Time and tap Turn On Screen Time. After you see an introductory splash screen, tap This Is My iPhone to go to the main Screen Time screen.

Two options on the lower portion of this screen help you customize Screen Time overall. Tap Use Screen Time Passcode to create another passcode that controls access to Screen Time settings and lets you extend time limits. It’s designed for parents who let their children use their devices, but you could use it as a speed bump when overriding your self-defined limits.

If you use both an iPhone and an iPad, enable Share Across Devices to aggregate your usage. This syncs settings between your devices, so if you want different setups, keep this option off.

Downtime

To limit your usage according to a schedule, perhaps so you don’t get caught up in a game before bed, tap Downtime, turn on the Downtime switch, and set start and end times. Unfortunately, you can’t create multiple schedules for different portions of the day.

App Limits

When you tap App Limits and then Add Limit, Screen Time presents you with a list of categories and examples of your apps in each one. Select one or more—say Social Networking and Games—and then tap Add. Then set the amount of time you want to allow yourself overall for apps in that category. You can create multiple category limits with different amounts of allotted time.

If an app category is too broad, you can limit a particular app. Tap the Screen Time graph at the top of the screen, scroll down to the Most Used section, and tap an app in the list. At the bottom of that screen, tap Add Limit and specify a time limit.

There are a few exceptions to the apps limited by both Downtime and App Limits, regardless of your settings. The Phone app is always available, and Clock, Find My iPhone, Safari, and Settings appear to be exempt. For other apps you never want limited, tap Allowed Apps on the main Screen Time screen, and then tap the green plus button next to any app you want to allow. Apple adds FaceTime, Maps, and Messages to the Allowed Apps list by default, but you can remove them if desired.

Living with Screen Time

Screen Time alerts you 5 minutes before a time limit expires and displays a Time Limit screen when time runs out. Although the point of Downtime and App Limits is to help you stop playing the latest addictive game or reflexively checking Facebook, you can tap Ignore Limit to keep using the app, either for 15 minutes or for the rest of the day.

Screen Time also dims the icon for any affected app on the Home screen and puts a tiny timer icon next to the name. You can still open such apps, but you’ll go right to the Time Limit screen.

Equally as helpful is the way Screen Time reports on your usage so you realize how much you’re using different apps. It provides a weekly report, but you can always go into Settings > Screen Time to see your daily usage.

Tap that graph, and Screen Time lets you dive into the details, for example, by revealing your most-used apps, how often you pick up your device, and how many interrupting notifications you receive. Much of the information in this screen is interactive—tap various items to see more details or adjust settings.

Only you can decide if you’re using your iPhone or iPad more than you like, and only you can exercise the self-control to restrict your usage. But Screen Time highlights how you’re actually spending time, both as you’re doing it and after the fact. Give it a try!

Do you end up with so many tabs in Safari that it becomes impossible to read the truncated tab titles? There’s no shame in that, and Safari 12—which comes with macOS 10.14 Mojave and is a free update for 10.12 Sierra and 10.13 High Sierra—now offers an option to add an icon representing the Web site to each open tab. Called a favicon, this tiny image is usually carefully designed to identify its site and makes it easier to pick out the tab. To enable the feature, open Safari > Preferences > Tabs and select “Show website icons in tabs.” Unlike other Web browsers, Safari never shrinks a regular tab to just the icon, so you’ll always see the icon and some text.

Have you found yourself composing an email message on your Mac while staring glumly at the receipt or document you need to scan and attach to the message? Adding that scan to the message isn’t impossible, but until macOS 10.14 Mojave, it hasn’t necessarily been easy.

It’s super simple now, thanks to a new Mojave feature called Continuity Camera. It lets you take pictures or scan documents with an iPhone or iPad running iOS 12 and have those images show up immediately on the Mac, either in a document or on the Desktop.

Continuity Camera Basics

Apart from Mojave and iOS 12, Continuity Camera requires that the devices be on the same Wi-Fi network, have Bluetooth turned on, and be logged in to the same Apple ID, which must use two-factor authentication. Continuity Camera also requires explicit support in apps, which means for the moment that it works only in Apple’s apps, including the Finder, Mail, Messages, Notes, TextEdit, Pages, Keynote, and Numbers. We aren’t aware of any third-party apps that support it yet.

How you access Continuity Camera can vary by app, but the most common approach is to Control- or right-click where you want the scan or photo to go. Look either for commands for Take Photo and Scan Documents, or for an Import from iPhone or iPad submenu, under which those commands will be replicated for each device.

The Take Photo and Scan Documents commands may also appear in the File menu or in an Insert menu. Plus, Mail composition windows have a drop-down menu on the right side of the toolbar that includes those commands.

Should you import directly into an app, or onto the Desktop? It’s up to you, of course, but adding a file to the Desktop that you can then drag to its eventual destination gives you more options for reuse or modification, along with backup. That could be important since the photos and scans aren’t stored on the iPhone or iPad.

Using Continuity Camera

Follow these steps to use Continuity Camera to take a photo or scan a document to your Mac. Because it’s the most likely scenario, we’ll describe importing to the Desktop from an iPhone, but the steps are the same for importing into any supported app or from an iPad.

First, Control-click the Desktop and choose either Import from iPhone > Take Photo or Import from iPhone > Scan Documents. A dialog appears on the Mac screen, telling you to use the iPhone to take the photo or scan the document. The iPhone displays a variant of the Camera app automatically.

If you’re taking a photo, you can switch between the rear- and front-facing cameras, pinch out to zoom, or enable the flash with the flash button. All you need to do is tap the shutter button. If the photo is blurry or otherwise unusable, tape Retake to try again, but if you like it, tap Use Photo. The picture shows up immediately on your Mac as a JPEG file.

If you’re instead scanning a document, you also get a Filters button that lets you set the scan type: color (the default), grayscale, black-and-white, or photo. By default, the scanning interface takes a picture automatically when it detects a document. If it moves too fast for you, tap Auto (at the upper right) to switch to Manual. Then tap the shutter button to capture the image, after which you may drag the circles to identify the document corners better. Then tap Retake or Keep Scan. If it’s a multi-page document, flip the page and continue scanning to add more pages. When you’re done, tap Save to send the document to your Mac as a PDF.

That’s it! The first time or two might seem a little awkward, but once you get the hang of Continuity Camera, it’s a wonderfully quick way to get a scan or photo onto your Mac.

Before iOS 12, Apple Maps was the only mapping app you could run on the dashboard in a CarPlay-equipped automobile. But Maps doesn’t always work well, and some people prefer directions from Google Maps or the Google-owned Waze. Once you upgrade your iPhone to iOS 12 and update to the latest version of Google Maps or Waze for iOS, you’ll be able to use those apps on your CarPlay screen. Happy navigating!

We love the Do Not Disturb feature in iOS—it’s essential for keeping notifications from waking us up at night or causing embarrassing light and noise in dark movie theater. But it’s long had a problem. When you invoked Do Not Disturb manually for a movie or doctor’s appointment, you had to remember to turn it off manually when you were done, or risk missing important notifications. No more!

In iOS 12, Apple enhanced Do Not Disturb in two ways: enabling it to disable itself automatically after a certain amount of time or when your location changes and adding a Bedtime mode that holds all notifications until you wake up.

An Automatic End to Do Not Disturb Sessions

In previous versions of iOS, you invoked Do Not Disturb manually by tapping its button in Control Center. However, if you forgot to turn it off after your meeting, say, it would stay on forever unless you had a Do Not Disturb schedule set, and even then, not until the end of that schedule. So if you forgot to turn Do Not Disturb off after a 10 AM meeting, it could stay on until the next morning or until you realized you weren’t getting any calls or messages.

If you start Do Not Disturb sessions in the same way in iOS 12, they’ll act the same way. But if you force-touch or press and hold the Do Not Disturb button in Control Center, that brings up the Do Not Disturb card with five options:

• For 1 hour: This first choice tells Do Not Disturb to hold all your calls for an hour, after which it will turn off automatically.
• Until this evening/Until tomorrow morning: If you invoke this option during the day, it will silence calls and notifications until 7 PM. Select it at night, however, and it will quiet your iPhone until 7 AM.
• Until I leave this location: Use this choice when you’re invoking Do Not Disturb in conjunction with being in a particular spot that you’ll leave as soon as you’re done.
• Until the end of the next event: When you enable Do Not Disturb during an event on your calendar, this choice appears, giving you the option of turning off Do Not Disturb at the end of the event.
• Schedule: Tap this button to open Settings > Do Not Disturb.

While Do Not Disturb is on, iOS 12 puts a notification on the Lock screen telling you when it will turn itself off. At any time before then, you can tap the Lock screen notification to allow calls and notifications again.

Do Not Disturb During Bedtime

In Settings > Do Not Disturb, you’ll find a new Bedtime switch. When enabled during the times for which you’ve scheduled Do Not Disturb, it dims and blacks out the Lock screen, silences calls, and sends all notifications to Notification Center instead of showing them on the Lock screen.

The idea behind the Bedtime switch is that it reduces the chances that glancing at your iPhone in the middle of the night to see what time it is will shock your eyes or engage your brain. Sleep is good! But if you get up early and want to allow notifications through again, tap the Do Not Disturb notification on the Lock screen to turn it off.

That’s not all you can do with Do Not Disturb During Bedtime. You might know that there’s a Bedtime screen in the Clock app that’s designed to help you go to bed and wake up at the same time every day. If you use it to set your desired sleep schedule and enable the Do Not Disturb During Bedtime switch in Clock > Bedtime > Options, you get another Do Not Disturb schedule.

That could be extremely welcome if, for instance, you want Do Not Disturb on automatically both at night when you’re sleeping and also during a regularly scheduled class or meeting.

Give these new Do Not Disturb options a try! They go a long way toward ensuring that our iPhones fit into our lives better, rather than forcing us to pay attention to every last alert or message.

When you double-click a document, macOS uses the document’s file extension to figure out which app should open the file. So, by default, a PDF file called laser-squid.pdf opens in Preview because the Finder knows that everything with a .pdf extension should open in Preview. But what if you would prefer to open .pdf files in Adobe Reader, or you want comma-separated value (.csv) text files to open in Numbers? To change any mapping, select a file of the type in question and choose File > Get Info to open the Info window. In the Open With section, click the pop-up menu to choose the desired app and then click the Change All button.

Apple may have discontinued its AirPort Wi-Fi base stations, but in a surprise parting gift, the company has released a firmware update to the AirPort Express that gives it AirPlay 2 capabilities like multi-room audio. If you have an AirPort Express connected to speakers through its audio jack, first use AirPort Utility on the Mac or iPhone to update its firmware to version 7.8. Once you do that, you’ll be able to play audio simultaneously through the AirPort Express and to other AirPlay 2–enabled devices, such as the HomePod and Apple TV.

Unless you can palm a basketball, you may not be able to use an iPhone single-handed. But sometimes one hand is all you can spare. If you find yourself in such a situation, give Reachability a try. On a Touch ID–based iPhone, tap (don’t press) the Home button twice to slide the iPhone’s interface halfway down the physical screen, bringing everything into reach of your thumb. On the Face ID–equipped iPhone X, put your thumb in the bottom of the screen—about at the top edge of the Dock if you were on the Home screen—and swipe down. You can use apps normally for a tap or two, and then they’ll expand back to the full screen to show the full interface. If Reachability is off (or if you want to turn it off), go to Settings > General > Accessibility.

By default, Apple locates the Dock at the bottom of the Mac’s screen. If that location interferes with you seeing as much of your document windows as you’d like, you can set it to appear only when you move the pointer to the bottom edge of the screen. But there’s a better way: put the Dock on the side of the screen where there’s plenty of horizontal room and it won’t get in the way of most document windows. Open System Preferences > Dock, and select Right or Left from the Position on Screen radio buttons.
