Although Apple’s eye-catching Desktop image of the High Sierra mountains makes it easy to confirm that your Mac is running High Sierra, the most noteworthy new features are invisible! These changes are aimed at improving your Mac’s performance. But, don’t worry that there’s nothing new in High Sierra, which came out on September 25th, to play with—you’ll find plenty to do in Apple’s apps, and I’ll share my favorite features below.

Apple’s invisible, under-the-hood changes modernize the Mac. The new APFS file system significantly improves how data is stored on your disk. It replaces the HFS+ file system, which dates from the previous century. You’ll notice the switch to APFS when you look up the size of a selected folder or duplicate a large file because the operation should run much more quickly. APFS also provides better FileVault encryption and reduces the chance of file corruption.

Also new is HEVC, a new video compression standard that will let videos stream better and take up less space on your drive, and HEIF, an image format that boasts significantly better compression to keep photos from overwhelming your drive. HEVC and HEIF have other advantages too, but they’re so embedded into High Sierra (and iOS 11) that all you’ll notice is more space. When you drag images and videos out of Photos, they’ll come out in familiar formats suitable for sharing.

Photos 3

In Photos, it’s now easier to browse your photos from the always-on sidebar on the left side of the window. Photo editing is also more streamlined, with the Edit screen now separated into three tabs: Adjust, Filters, and Crop.

You can now edit Live Photos! Look at the bottom of the Adjust tab for controls for picking any frame as the static “key” frame, trimming the video, and applying special effects. The most interesting effect blurs the Live Photo by turning the 3-second mini-movie into a single long exposure.

Those who are into tweaking photos by hand should check out the new Curves and Selective Color options on the Adjust tab. Or, if you’d prefer that your Mac do the heavy lifting, try the new filters on the Filters tab.

My favorite new feature is more of a fix—when you train Photos to match faces with names, that training will now sync through iCloud Photo Library to your other Apple devices. About time!

Finally, for serious photographers, Apple has at long last brought back round-trip editing of a photo in an external app, like Pixelmator or Photoshop.

Safari 11

I seem to always bounce between using Chrome and Safari, but the new version of Safari may make me a permanent convert. A new Websites tab in Safari’s preferences lets you specify Web sites that should always open in Safari’s clutter-reducing Reader View, blocks some ads and auto-play videos, lets you set the zoom level on a per-site basis, and more. I like to tweak these options for the current Web page by choosing Safari > Settings for This Website to open a popover with the necessary controls.

And in the “Thank you, Apple!” category, Safari now offers Intelligent Tracking Protection (ITP), which limits advertisers’ cross-site tracking of where you’ve been online.

Notes 4.5

Notes now offers a capable Table feature and a handy File > Pin Note command that puts the selected note at the top of its list rather than listing it by order last edited. Neither feature is earth shattering, but I’m enjoying both already.

Mail 11

Behind the scenes, Mail gets a welcome change you probably won’t notice—according to Apple, message storage now takes 35% less space. How do they do this? I have no idea, but if it’s true this is great news!

More obvious is how Mail revamped its behavior in full-screen view. Instead of the message-composition area overlapping most of the Mail window, the screen splits, and your new message appears at the right. This layout simplifies viewing an older message while drafting a new one.

FaceTime 4

A fun new FaceTime option is taking a Live Photo of your call. It’s a perfect way to record mini-movies of far-away relatives. If the person you’re chatting with allows Live Photos in FaceTime’s preferences, hover over the FaceTime window to see and then click the round Shutter button.

Spotlight

Spotlight isn’t exactly an app, but it lets you search for anything on or off your Mac. Click the magnifying glass icon at the right of your menu bar—or press Command-Space bar—to start, and then enter your search terms. New in High Sierra, you can enter an airline flight number to see oodles of flight-related info.

High Sierra won’t radically change how you use your Mac, but I’m in favor of anything that makes our Macs run faster and keeps our drives from filling up so fast. Should you upgrade? Yes. When? That’s another story. I’d recommend waiting for at least a month, and perhaps until early next year, to upgrade. This will give Apple time to work out any bugs that might be lingering.

Apple does a great job with Macs, iPhones, and iPads, but stuff goes wrong all the time—as professional providers of technical support we know that better than anyone. So we’re really cheesed off by tech support scams that try to defraud unsuspecting users in the name of fixing problems that don’t exist. I’ve had this happen to a number of clients, so here’s how to protect yourself.

How Tech Support Scams Work

Tech support scams start by trying to get you on the phone. You might see an alarming pop-up message informing you of some problem and giving a number to call for help, end up on a Web site that offers a free “security scan” that will pretend to find problems and urge you to call, or even receive a direct cold call from someone claiming to be from Apple, Google, or Microsoft.

Once you’re on the phone, the scammers’ goal is to convince you to pay them to solve your “problem.” They do this by throwing around technical terms and having you look at low-level files that, they’ll say, show evidence of issues like malware infection or file corruption. They may even ask for remote access to your Mac using legitimate software like TeamViewer and use it to show you log messages that look like concerning errors.

If you fall for this tech talk, the scammers close in for the kill. They may ask for your credit card number to pay for the “services” they’ve rendered, enroll you in a fake maintenance or warranty program, sell you software that is normally available as a free download, or install malware that will give them continued access to your computer. Not good.

How to Protect Yourself from Tech Support Scams

Luckily, it’s easy to ensure that you don’t get scammed.

• Never call a phone number that appears in a pop-up dialog, no matter what it says. Legitimate messages will never ask you to do that.
• If you get an unexpected call from someone you don’t know claiming to be tech support, hang up immediately. Don’t be fooled by caller ID, since it can be spoofed to look like the call is coming from a legitimate company, like Apple.
• Don’t give your passwords to anyone who contacts you on the phone, and never allow anyone you haven’t met in person (and trust!) to control your Mac remotely.

Of course, the awkward part here is that, if we do tech support for you and particularly if we’re using Watchman Monitoring to provide proactive notification of problems, we may need to call you and even ask for remote control of your Mac. We will always identify ourselves clearly, and if you’re at all concerned, you can call us back at a contact number you already have or ask us for some piece of information no scammer could know.

How to Recover from Being Scammed

First, we’re here to help for real, so please feel free to contact us for assistance. That said, there are three main things to focus on:

• Change any passwords that you shared. Plus, if you use the same passwords on any Web sites, change those passwords too. (And start using a password manager like 1Password or LastPass so every site can have its own secure password without you having to remember and type them.)
• If you have legitimate anti-malware software, run it to make sure the scammer didn’t install anything evil on your Mac. If you don’t have up-to-date anti-malware software, contact us to see what we recommend.
• If you paid for any bogus services, call your credit card company and reverse the charges. You can also report the incident to the U.S. Federal Trade Commission at ftc.gov/complaint.

Finally, beware of the “refund scam.” Several months after you’ve been scammed, you might get a call asking if you were satisfied with the service and offering a refund if you weren’t happy, or saying that the company is filing for bankruptcy and providing refunds. Either way, the scammer will then ask for your bank account or credit card number to process the refund, but instead of depositing money, will extract more. If you get a call like this, hang up immediately.

It’s easy, in some apps, to end up with oodles of open windows. You can usually switch between them by clicking those you can see or by choosing one from the Window menu, but wouldn’t it be nice to cycle through them from the keyboard, much as you can cycle through active apps with Command-Tab? You can! By default, the shortcut is Command-Backtick (the key above Tab), but if you want to change it to something else, open System Preferences > Keyboard > Shortcuts > Keyboard and look for “Move focus to next window” in the list. To change the shortcut, double-click right on it in the list and type your preferred alternative.

With watchOS 4 now arriving on Apple Watch users’ wrists, it’s time to make sure you aren’t missing out on any of the important features—and to share a few tips for how to use them. watchOS 4 works on all Apple Watch models, even the original Apple Watch. It does require iOS 11, so if you’ve been using your Apple Watch with an iPhone 5 or 5c, you’ll need to stick with watchOS 3 until you get a new iPhone.

#1: Dock Scrolls Vertically instead of Horizontally

Press the side button to see the Dock, and you’ll notice that it now scrolls vertically—this makes sense since one of the ways to scroll it is by turning the digital crown. You can now arrange Dock items (using the Watch app on your iPhone) based on either your favorites or which Dock items were used most recently.

#2: Useful and Fun Watch Faces

The new Siri watch face doesn’t add new speech capabilities, but it does show timely information, pulling in personal details and suggestions from apps such as Calendar, Reminders, and Photos. It also shows Now Playing controls when you’re playing audio on your iPhone, along with Apple News headlines and stock tickers. I liked it more after customizing its Data Sources in the iOS Watch app.

When you want something whimsical on your wrist, there’s now a Toy Story face. Or, try the trippy new Kaleidoscope face that changes slowly as time goes by—you can speed it up by turning the digital crown.

#3: App List Supplements Icon Cloud

The App screen’s icon cloud looks impressive, but it can be challenging to locate and tap a specific app. I’m appreciating the new List view, accessed by force-pressing the App screen, which displays apps alphabetically.

#4: Flashlight on Your Wrist

Swipe up to find and tap the new Flashlight button in Control Center, which turns the screen bright white. Swipe left to access a flashing option, designed to make you more visible at night while walking or running. Press the side button or digital crown to turn the flashlight off.

#5: More Fitness Encouragement and Options

The Activity app is now more chatty and will make suggestions in the morning to inspire you. It will also remind you at night if you are close to closing a ring.

Apple gave the Workout app some attention, too. Starting a workout is easier than before: it now requires only one tap, Do Not Disturb turns on automatically, and your default playlist can even start playing. With the workout underway, you can now switch easily to a different workout type (swipe right and tap the + button), and see a multi-workout analysis at the end of the entire session.

Swimmers using an Apple Watch Series 2 or 3 can now track sets and rests, pace for each set, and distance for each stroke type. Apple also has added a High Intensity Interval Training workout type.

Finally, your Apple Watch can connect with some gym equipment, like ellipticals and indoor bikes, allowing it and the machine to share data. Look for an NFC label on your machine, and tap it with your watch.

#6: Multiple Playlists On the Go

The Apple Watch is great for playing tunes to AirPods while you work out, but with watchOS 3 you were limited to just one playlist. With watchOS 4, you can sync multiple playlists and albums via the Music settings in the iOS Watch app. Plus, for Apple Music subscribers, your automatically generated favorites mixes can sync automatically.

#7: More App Enhancements: Phone, Timer, and Camera

Other apps also receive improvements in watchOS 4. You can dial phone numbers manually with a new keypad in the Phone app. Timer now has a Repeat button, so you can repeat a timer with a single tap. And the Camera app offers some new remote options, including support for starting and stopping videos.

All-in-all, watchOS 4 is a solid upgrade, and the changes will make your Apple Watch both more useful and easier to use.
