With Apple’s productivity apps like Calendar, Contacts, Notes, and Reminders, which look and work pretty much the same on the Mac and in iOS, what you see is largely what you get. Particularly in iOS, they tend not to have much in the way of hidden depths.

With Reminders, however, Apple’s engineers snuck some surprising little features into the Mac version. We like using Siri on the iPhone, Apple Watch, and HomePod to add items to our iCloud-synced Reminders to-do lists and shopping lists whenever we think of them. And then, when we’re at our Macs, all those reminders are waiting for us. Here are some useful tricks on the Mac that you may not have noticed.

Open List in New Window

By default, Reminders is a single-window app with a sidebar that shows all your lists. You can hide the sidebar to focus on a single list at a time, at which point you navigate between lists by clicking the dots at the bottom of the screen or swiping on a trackpad.

But what if you want to see multiple lists at once? You can open any list in its own window by double-clicking it in the sidebar or by choosing Window > Open List in New Window. Resize and position that window as you like. Reminders even remembers which lists you had open if you quit and relaunch (and if it doesn’t, deselect the “Close windows when quitting an app” checkbox in System Preferences > General).

Check Today’s Tasks and Notice the Scheduled List

Perhaps the best part of making reminders is telling Siri to alert you at a particular time. “Hey Siri, remind me to test my backups on Friday the 13th at 9 AM.” Such reminders work well if you just want a notification at that time, but for those who like to see what’s coming up, Reminders has a few features for you.

To see what you’ve scheduled for today, choose View > Go to Today—we prefer the Command-T shortcut. To expand your view of tasks to those you didn’t finish yesterday (drat!) and those that are coming soon, click the automatically generated Scheduled list at the top of the sidebar. (It also exists at the top of the list of lists in the iOS version of Reminders.) The Scheduled list shows every reminder that has an associated time—it’s helpful for longer-term planning.

The Scheduled list may become overwhelming if you schedule lots of tasks, so Reminders on the Mac has one more trick for helping you view your tasks by date. Choose View > Show Calendar to display a tiny calendar at the bottom of the sidebar. Any date that has tasks on it gets a dot underneath; click one to see that day’s items.

Set and Sort By Priorities… Or Not

For those who have so many tasks that they need to prioritize them to stay on track, Reminders provides four levels of priority: None, Low, Medium, and High. To set and reset them quickly for a selected to-do, use the keyboard shortcuts:

• Command-1 for Low
• Command-2 for Medium
• Command-3 for High
• Command-4 for None

Once you’ve set priorities, choose View > Sort By > Priority to put your most urgent items at the top. Alas, if you have multiple Reminders lists open at once, the Sort By setting applies to all of them. So you might want to switch back and forth between Priority and other sorts, such Due Date, Creation Date, or Title. Or choose Manual and drag the items into the order you like.

Other Shortcuts

If you want to move an item from one list to another, you can drag it. The trick is to click to the left of its circle or the right of its name; clicking on the name will start editing. You can also Command-click to select multiple items or Shift-Click to select a range of items.

Although clicking the i button that appears when you hover over an item lets you set its notifications and priority, it’s easier to double-click the item. Or, you can Control- or right-click to the left of any item to update it too. Even better, select multiple items first, and then Control- or right-click them to modify them all once! And if your goal is to delete unnecessary items rather than marking them as completed, just select them and press the Delete key.

Reminders may not be the most full-featured to-do list app, but with these tricks and its Siri integration, it can be surprisingly powerful.

A client got in touch recently with a maddening problem. When he received texts on his iPhone, Messages displayed notifications for messages from everyone…except his wife! Needless to say, this was a problem. Since notifications appeared correctly for other people, it wasn’t related to overall settings. It turned out that he—or someone else, or iOS gremlins—had inadvertently enabled the Hide Alerts switch for the Messages conversation with his wife. To fix it, all he had to do was display the conversation in Messages, tap the i button at the upper right, and disable Hide Alerts. (In the Mac version of Messages, click the Details button and look for the Do Not Disturb checkbox.) It’s a good feature designed to let you mute a chatty group conversation, but it can cause stress if applied to the wrong conversation accidentally.

Dragging files and folders around is core to the Mac experience—drag a file from one folder to another to move it, drag a folder from one drive to another to copy it. But did you know that if you hold down the Option key while dragging a file in the Finder, you’ll get a green + pointer and it will make a copy in the destination? That’s easier than duplicating, moving, and renaming the file. Similarly, if you want to move a large folder from one drive to another, hold down the Command key during the drag to do in one step what would otherwise require copying, trashing, and emptying the Trash. Finally, if you want an alias, hold down the Command and Option keys while dragging, and presto, the original stays put and an alias appears in the destination.

If you’re working on an iPad with a physical keyboard—either a Bluetooth keyboard or an iPad Pro with Apple’s Smart Keyboard—there are quite a few keyboard shortcuts you can use to work faster. Many are what you’d guess if you have Mac experience; for instance, Command-F generally maps to Find. But to see a list of supported keyboard shortcuts in an app, simply press and hold the Command key on the keyboard until an information panel appears. Some apps, like Calendar (shown below), even have multiple pages of shortcuts; swipe to see them all. Not all apps will display the cheat sheet, but most of Apple’s productivity apps do.

When it comes to calendars, we’re mostly concerned with the future. But sometimes you want to travel back in time too, to see when you had that doctor appointment or last went to the gym. If you scroll back in the Calendar app in iOS, you might discover, to your consternation, that after 2 weeks back, the only items in your calendar are old repeating events. What gives? Weirdly, since calendar events consume almost no storage space, iOS lets you select how far back to sync events from your master calendar. Choose a time period in Settings > Calendar > Sync, or to eliminate any possibility of confusion, just select All Events.

Facebook has dominated the news headlines of late, but not for good reasons. There were the 50 million Facebook profiles gathered for Cambridge Analytica and used in the 2016 presidential election. Facebook has long been scraping call and text message data from Android phones. And within the Facebook iOS app, the company pushes the Onavo Protect VPN, an app made by a subsidiary that literally collects all your mobile data traffic for Facebook.

Because of this, many have encouraged Facebook users to delete their accounts. That even includes the billionaire co-founder of the WhatsApp messaging service, which Facebook bought in 2014. If you’re done with Facebook, you’re welcome to deactivate or even delete your account. Facebook provides instructions for both actions. Deactivating your account basically just makes you invisible on Facebook, whereas deleting your account may eventually (up to 3 months) result in most of the data being removed.

The problem is that Facebook is useful. It may be the only connection you have with certain friends or family members, and many informal groups use Facebook for meetup logistics. For many of us, losing access to Facebook would hurt our real-world relationships and activities. Plus, lots of companies have Facebook pages, and taking those down might result in a loss of business from customers who would find out about the firm only through Facebook. What to do?

If you’re a business, the most sensible tack is to keep your Facebook page but avoid relying on it. Remember, Facebook is not your friend. Earlier in 2018, Facebook announced that it would be prioritizing posts from friends and family over public content, which is a nice way of saying that Facebook is deprecating business-related posts. So make sure you have a Web site that you control, and make sure that customers can easily find it and contact you through it. It’s also a good idea to offer customers multiple ways to contact you, including via email.

On a personal level, there are two ways to think about privacy on Facebook: limiting the information you share with other people on Facebook, and limiting the information that you’re willing to provide to Facebook at all. If Facebook doesn’t have certain data about you, they can’t sell it to the highest bidder, let it be harvested by hackers, or use it in ways you might find creepy.

To control who on Facebook can see what you share, click the ? button on the Facebook Web site on your Mac, or tap the hamburger button in the bottom right corner of the Facebook iOS app and tap Privacy Shortcuts. Then click or tap Privacy Checkup and run through the steps to make sure you’re sharing the right info with the right people. Be sure to lock down or remove any apps that you don’t need, since they can leak all sorts of data.

Also, go to Facebook’s Privacy Settings & Tools page. Click the Edit button next to each item, and make it as specific as you can. You also might want to review the posts you’re tagged in and remove those that you don’t want on your timeline.

But what if you don’t want to give information to Facebook for it to use? Go to Facebook’s page for Uploading and Managing Your Contacts, and delete them all. You’re just giving away your contacts’ personal information without their permission otherwise.

To ensure that contact uploading doesn’t happen again, in the Facebook iOS app, tap the hamburger button, scroll to the bottom, and then tap Settings & Privacy > Account Settings > General > Upload Contacts and make sure the switch is off. (Some versions of the Facebook app just have Settings, not Settings & Privacy, and show a popover for Account Settings.)

Also, in the iPhone Facebook app, tap the hamburger button again and then Settings & Privacy > Account Settings > Location > Location, and make sure it’s set to Never. And whatever you do, keep Location History off—Facebook doesn’t need to know everywhere you’ve ever been.

If you’re perturbed by the way Facebook’s iOS app is trying to capture your contacts and locations, you could delete it from your iOS devices and rely instead on the Facebook Web site, which can’t access nearly as much information about you. To make it easier to open, in Safari, visit facebook.com, tap the Share button, and then tap the Add to Home Screen button in the bottom row of the share sheet.

Let us leave you with one thought. Always assume that anything you post to Facebook or allow Facebook to have access to could end up on the front page of your local newspaper… or the New York Times. Nothing on Facebook is ever completely private—Facebook has shown it isn’t trustworthy or reliable—and the best way to ensure confidential information doesn’t leak inadvertently is to avoid posting it to Facebook in the first place.

Here’s one for those who use Apple’s Notes app for storing bits of information. By default, Notes in macOS gives you a single window, with each note listed in a sidebar. But what if you want to see two notes at once? Or keep one always available no matter what else you’re doing? Select the desired notes in the sidebar by Command-clicking them, and then choose Window > Float Selected Notes to open them in their own windows. Or, just double-click them in the sidebar! Then, to make sure one or more of those windows is never obscured by another app, make it active and then choose Window > Float on Top. It’s still a normal window that you can move and resize and close, but no other app will appear over it. See how Safari is the frontmost app below, but the Notes window is on top?
