Apple CEO Tim Cook gave the commencement address at Duke University this morning. He urged the newest graduates of his alma mater to fearlessly face the challenges that trouble the world today, and assured them that technology gives them to power to do so.

Problems Cook mentioned include political divisions, climate change, and societal inequality. But he also told the graduates, “You are not powerless to fix them. No generation has ever had more power than yours, and no generation has a chance to change things faster than yours can.”

This week we’ll search for photos of hotdogs with Retrobatch, hike the Appalachian Trail with Gaia GPS, and learn foreign with the new Duolingo.

We live in a visual age, so the ability to use apps like Photoshop, InDesign, and Illustrator are super marketable. Even better if you can back up your resume entry with certification.

A lawsuit filed in federal court claims that the keyboard used in all the MacBook Pros and MacBooks made in the past few years is defective. The plaintiffs request that this be made into a class-action lawsuit, and that Apple be required to replace all the affected keyboards at no cost to users.

The lawsuit also requests punitive damages because, as the plaintiffs claim, Apple continued to build and sell laptops with the “butterfly” keyboard even though the company knew it was defective.

Whether you love it or you’re on the fence, this week you can save big on an Apple HomePod if you’re willing to shop in-store. Plus, we are seeing an all-time low price on the Apple Watch Series 1 Sport!

Animation and graphics are one of the best ways to connect a message with an audience, whether it’s an explainer, a commercial, or just a skit. Technology has made it so that you don’t need a render farm to make animated content. You just need the right app.

In this week’s Cult of Mac Magazine: The Activity Rings on your Apple Watch don’t provide a complete picture of your fitness. There is one important ring missing: Strength. The Rock didn’t get ripped just by standing up once an hour. And both the Exercise and Move rings essentially measure the same thing: cardio.

As any fitness expert will tell you, an effective workout program should combine cardio with strength training. Here’s why strength is currently Apple Watch’s weakness, and how you can use third-party apps to make sure it isn’t yours as well.

You’ll find that story and more in this issue. Get your free subscription to Cult of Mac Magazine from iTunes. Or read on for this week’s top stories.

The iPhone and iPad are arguably one of the most powerful computers most of us own. While much argument has been had as to whether you can do real work on iOS, apps are a proving ground for what an iOS device is capable of. Coda for iOS harnesses the power of iOS to make a feature rich programming app, turning your iOS device into a shell terminal, FTP client, remote file viewer, and pocketable coding app.

Apple is famously bad at social networks. Unless you count iMessage, which is easily successful and popular enough to exist as a standalone business. Or iCloud Photo Sharing, which brings families and friends closer together every day. What’s that you say? Ping? Sure, that didn’t work out, but using it as your sole representation of Apple’s social efforts is lazy at best.

Apple, then, is pretty good at social stuff. It’s just that it’s hidden. For instance, now you can hook up with friends in Apple Music, and spy on what they’re listening to. How? Let’s see.

Building construction is an immensely complex process. The firm Rogers-O’Brien uses hundreds of iPads to simplify it, while saving 55,000 hours of employee time and $1.8 million annually.

All the paperwork involved is stored in the cloud where it can be accessed at any time. This means someone in the office can make a change and the people in the field can immediately see the updated document.

New renders of the upcoming iPhone SE 2, which depict its gorgeous glass back, have been revealed by a popular case-maker.

Olixar is already producing accessories for the device based on information it has gleaned from sources in China. Its new screen protector indicates the iPhone SE 2 will be a big surprise, with an edge-to-edge display just like iPhone X.

The Apple Watch is credited with potentially saving its wearer’s life after 76-year-old man Gaston D’Aquino was recently told to go to hospital after being informed of an unusually high heart rate.

Despite feeling fine, D’Aquino discovered that two of his three coronary arteries were blocked, while the remaining one was only functioning at 10 percent of its usual capacity.

Sharing things is what the internet does best. So there shouldn’t be any friction involved in getting content from your screen to those of your team. But if you’re not using the right platform, friction is what you’ll get.

Snapchat has caved in to demands to reinstate the old Snapchat look. Well, kind of.

The self-destructing messages service is currently rolling out a new design to iOS users, undoing at least a few of the contentious changes it introduced with its previous redesign.

Microsoft wants to work with Apple to bring iMessage to Windows machines.

The company’s upcoming Your Phone app will seamlessly sync content between your iPhone and your Windows 10 PC, but unlike those with an Android device, you won’t be able to sync messages. Microsoft is hoping it can team up with Apple to change that.

Tim Cook will give the commencement address for Duke University’s graduating class this Sunday, May 13. Cook graduated from Duke’s Fuqua School of Business with an MBA in 1988.

“I’m honored to be returning to Duke this weekend to help celebrate the Class of 2018,” Cook told Duke University’s Chronicle newspaper this week. “I graduated from Fuqua 30 years ago, and the friends and memories I made at Duke are among the most treasured of my life.”

There’s a whole YouTube channel devoted to HDR videos, and the iPhone X can now display them as they are meant to be seen.

High Dynamic Range offers a greater span of colors that most screens can display. The OLED display in Apple’s flagship device is up to the job, though.

Best List: Clessant Gold Barenia Apple Watch Band

When it comes to fashion, it’s hard to beat basic black. However, sometimes you want a little something extra — a color and design that adds subtle interest without going over the top. The Clessant Gold Barenia Apple Watch band joins its black counterpart and does the trick, thanks to fine off-white stitching that looks almost like racing stripes.

Just a glance at an iPad or Apple Watch shows how much aluminum Apple uses. The traditional method for producing this material creates greenhouse gases. Apple brought together a pair of companies to develop a greener aluminium smelting process that releases oxygen instead.

The metal will someday go into iPhones, Macs, and other devices to make them easier on the environment.

Imagine shooting video with a dual-camera iPhone with simultaneous capture through both lenses.

Apple has and it applied for a patent indicating software to record with both the wide and zoom lenses on a device is somewhere in the pipeline.

Apple is working with Goldman Sachs to release a credit card, according to an unconfirmed report. This will apparently take the place of the company’s current Rewards Visa.

The card will be offered under the Apple Pay brand. Goldman Sachs will allegedly replace Barclays as Apple’s partner for credit cards.

Suppose you’re listening to some music, then glance over an realize your iPhone has loaded a porn site all on its own. That’s the nightmare scenario researchers say is possible after they proved voice commands can be concealed in songs.

It’s also possible to get Siri to recognize commands given at frequencies outside the range of human hearing.

When the first iMac debuted 20 years ago, it shook the tech world with its completely unorthodox appearance. The blobby, curvaceous and colorful computer looked, in Steve Jobs’ words, good enough to lick.

It was a statement computer, both for those who owned it and for those who made it.

However, with the iMac not having had a substantial redesign since 2012, Apple’s all-in-one desktop is getting a bit long in the tooth. It’s time for Apple to give it an overhaul with a new iMac design that would get the world excited about Macs again — and prove Apple remains committed to innovative computing.

Apple’s new iPhone SE, expected to make its debut this month, may not be a clone of its predecessors after all.

One popular accessory-maker, which has already started producing screen protectors for the device, expects the iPhone SE 2 to feature an edge-to-edge display with a notch — just like iPhone X.
