New MacBook Pros Add Context-sensitive Touch Bar

At its “Hello Again” special event, Apple finally unveiled new models of the 13- and 15-inch MacBook Pro, the first update to the company’s professional laptops since May 2015 (see “Apple Releases Updated MacBook Pro, iMac, and iPhone Dock,” 19 May 2015). The new models boast an updated industrial design that takes cues from the 12-inch MacBook to reduce size and weight. They also introduce the Touch Bar, an entirely new, context-sensitive input device that replaces the function keys above the keyboard with a multi-touch–capable Retina display that includes an integrated Touch ID sensor. Unsurprisingly, given how much time has passed since the previous models were released, the new MacBook Pros feature significantly improved performance as well.

Reach Out and Touch the Bar — Sure, the new MacBook Pros are smaller, lighter, and faster, but the big news is the new Touch Bar. It’s a multi-touch–enabled strip of glass that extends to the full width of the keyboard, and with a display height about as deep as the row of function keys that it replaces: just over 0.4 inches (1.02 cm). Unfortunately, it does not have either 3D Touch/Force Touch, or a Taptic Engine, so it accepts only simple touches and doesn’t provide any feedback.

Underneath the glass is a 2170-by-60–pixel Retina display that apps can use to show context-sensitive tools. Because it’s multi-touch and can handle up to 10 simultaneous touch inputs, app developers are letting their imaginations run wild with Touch Bar possibilities.

In Photos, for instance, depending on what you’re doing, the Touch Bar lets you scrub through your photo collection, mark photos you love, and edit photos. Once you use it to select a photo for editing, the Touch Bar changes to provide editing tools, such as exposure and color sliders and rotation controls. In video editing apps such as Final Cut Pro X, the Touch Bar can provide a timeline scrubbing control along with trimming tools.

Every app will take advantage of the Touch Bar in its own ways. For example, for those addicted to emojis, apps like Messages could display available emojis in a scrollable strip. The Touch Bar can also provide the QuickType suggestions familiar to iOS users.

Apple also showed how you can customize at least some of the Touch Bar’s tools, much like how you can choose which buttons appear in the toolbars of many Mac apps. Customizing the Touch Bar in the Finder, for example, presents an interface similar to that used for editing window toolbars, letting you drag buttons and controls down to the Touch Bar from an on-screen display of available items.

At the far right of the Touch Bar is an integrated Touch ID sensor, which enables you to log in to your Mac with the press of a finger, just like on an iPhone or iPad. Actually, it’s even better, since you can use different fingers to access different accounts on your Mac at startup or via fast user switching. For example, you could have your right index finger log you in to your main account, set your right pinky to log you into a troubleshooting account, and let your spouse log in to yet another account. The Touch ID sensor communicates with a new Apple T1 chip that includes a Secure Enclave for storing Apple Pay information for use within Safari on the Web.

For those who still rely on function keys, a press of the physical Fn key in the lower-left corner of the keyboard instantly flips the Touch Bar back to showing classic F1 through F12 function keys.

Apple executives Phil Schiller and Craig Federighi made plenty of jokes about people still needing IBM 3270 terminal function keys, but realistically, some people have long relied on the function keys as universal shortcut keys. OK, maybe it’s just me, but 25 years ago, I determined that I would be more productive if I could always invoke my preferred writing tool with F1, my email app with F3, my file transfer app with F4, and so on. (F2 brings up my default Web browser; obviously, that particular mapping came more recently.) If I end up buying one of these Touch Bar-enabled Macs, I’ll have to see how I end up using it.

What about the Esc key, the apparent absence of which has prompted all sorts of reactions from Apple observers? Apple reserves the left end of the bar for a “system button” that is either the Esc key or some other system-provided button, depending on the context. So, in the rare event that you need to force-quit an application, Command-Option-Esc is still an option.

In fact, Apple’s developer guidelines say that the Touch Bar has three regions: the system button area, a central app region where app-specific controls go, and a control-strip spot to the right where users can manage system level tasks like adjusting the volume or brightness — this is where the dedicated Siri button lives. Users can completely hide the control-strip region in order to display more app-specific controls, and they can also choose to hide the app region.

On the one hand, the Touch Bar is a fascinating innovation on Apple’s part. It could revolutionize how Mac users, particularly professionals who manipulate the interfaces and controllers for their apps like musical instruments, interact with virtual software worlds.

On the other hand, Apple needs to go all in with the Touch Bar if it’s to become a core part of the Mac experience. Right now, it’s available only on the new 13- and 15-inch MacBook Pros. Nor did the company even hint about a new Magic Keyboard that could be used with desktop Macs. I suspect developers will support the Touch Bar right away just because it’s cool and new, but if Apple doesn’t make it universal across the product line, support will wane over time. Plus, regardless of how much better these new MacBook Pros are than the models they replace, many new buyers won’t consider them because of the inherent tradeoffs in working on a laptop versus a desktop, such as reduced performance, worse ergonomics when used at a desk, and higher cost for an equivalently powerful setup.

In SlackBITS, where we and numerous other TidBITS readers were kibitzing about the presentation as it happened, we also were pondering whether or not the Touch Bar is better or worse than a fully touch-sensitive screen, such as is available in many Windows laptops and Chromebooks. And if the Touch Bar’s location on the keyboard is better for ergonomic and user interface reasons, what does that say about iOS, which is all about touch-based direct manipulation of the interface? Might iOS 11 offer apps the option of including a virtual Touch Bar at the bottom of the screen as a consistent interface element, or even replace the Home button with a Touch Bar?

In any case, the idea of a separate multi-touch display dedicated to input and control in addition to the main computer display is powerful, and it will be interesting to see how its use evolves over time.

Size and Weight — Back at the basics, the new MacBook Pros do boast some impressive numbers. The 13-inch MacBook Pro is significantly smaller and lighter than the previous model:

  • Height: 0.59 inch (1.49 cm), down from 0.71 inch (1.8 cm)
  • Width: 11.97 inches (30.41 cm), down from 12.35 inches (31.37 cm)
  • Depth: 8.36 inches (21.24 cm), down from 8.62 inches (21.89 cm)
  • Weight: 3.02 pounds (1.37 kg), down from 3.48 pounds (1.58 kg)

In comparison with the 13-inch MacBook Air, the new 13-inch MacBook Pro is thinner (at the MacBook Air’s thick edge), narrower, and less deep — and it weighs just 0.06 pounds (27 g) more. The 12-inch MacBook is still smaller and nearly a pound lighter, but it has a smaller screen and, by comparison, an anemic CPU.

The new 15-inch MacBook Pro sees similar drops in size and weight from the previous model:

  • Height: 0.61 inch (1.55 cm), down from 0.71 inch (1.8 cm)
  • Width: 13.75 inches (34.93 cm), down from 14.13 inches (35.89 cm)
  • Depth: 9.48 inches (24.07 cm), down from 9.73 inches (24.71 cm)
  • Weight: 4.02 pounds (1.83 kg), down from 4.46 pounds (2.02 kg)

Functional Specs — One aspect of the new MacBook Pros will likely jump out at you when you see it: a Force Touch trackpad that’s twice as large as the trackpad on the previous models. In fact, as Phil Schiller noted, the Force Touch technology, which simulates the feel of clicking thanks to a Taptic Engine, is the only reason Apple could create such a large trackpad. It would be impossible to make a mechanical system that worked consistently across such a large surface. The additional size should be better for multi-touch gestures.

Both models feature improved screens as well. The resolutions remain the same — 2560 by 1600 for the 13-inch model and 2880 by 1800 for the 15-inch — but Apple claims the displays are 67 percent brighter, have a 67 percent higher contrast ratio, and show 25 percent more colors thanks to support for the P3 wide color gamut.

Apple has apparently learned its lesson from the 12-inch MacBook Pro, which garnered significant criticism for having only a single USB-C port for charging and expansion (see “The 12-inch MacBook: A Different Mac for a Particular User,” 29 April 2015). The new Touch Bar MacBook Pros go in the other direction, with two Thunderbolt 3 ports on each side, all four of which can be used for charging and expansion. And no, it won’t charge faster if you plug in two chargers; it just picks one.

Thunderbolt 3, which provides throughput up to 40 Gbps, uses the same connector as USB-C and supports DisplayPort (and thus HDMI and VGA, plus Thunderbolt 2, via adapters) and USB 3.1 Gen 2, which runs at 10 Gbps and is backward compatible with older USB devices. We’re planning to write more about Thunderbolt 3 and USB-C soon but for the moment, consider the fact that these new machines can drive two 5K displays or four 4K displays. That’s impressive.

At this point, I need to acknowledge that Apple actually introduced two versions of the 13-inch MacBook Pro. So far I’ve been talking about the high-end one, but for $300 less, you can get a model that lacks the Touch Bar, reverting to traditional function keys, and sports only two Thunderbolt ports on one side. Plus, it comes with slower processor options and a less-capable graphics processor.

So, in terms of processors, graphics, memory, and storage, here’s how the base models stack up. Apple is being quite confusing with the Touch Bar models, offering two configurations of each, with the cheaper version lacking certain options. For instance, the $1799 model of the 13-inch MacBook Pro doesn’t let you increase storage, whereas the $1999 model includes more storage and lets you choose more yet. On the 15-inch side, the $2399 model has a slightly slower CPU, less storage by default, and a less-capable graphics processor than the $2799 model, and charges more for upgrades. So shop carefully!

It can be hard to know how all the new components will affect real-world performance, since Apple improved the speed of everything, but the company is claiming improvements of 60 to 130 percent in various tasks. It’s safe to say that these are the fastest Mac laptops ever; what remains to be seen is how they compare to Apple’s desktop models.

In terms of wireless networking, 802.11ac Wi-Fi is standard across all models, as is Bluetooth 4.2. And despite Apple’s “courage” in dropping the headphone jack from the iPhone 7, the new MacBook Pros keep the 3.5mm jack, along with providing stereo speakers, three built-in microphones, and a 720p FaceTime HD camera. That’s one more microphone than the previous models, and a jump from Bluetooth 4.0, but those changes aren’t major.

Battery life should also be similar, although Apple rates the new 13-inch MacBook Pro at only 10 hours of iTunes movie playback, down from 12 in the previous model. That’s likely due to significantly smaller batteries; the old 13-inch model featured a 74.9-watt-hour lithium-polymer battery, whereas the non-Touch Bar model has a 54.5-watt-hour battery, and the Touch Bar model’s is slightly smaller yet, at 49.2-watt-hours. Similarly, the 15-inch drops from a 95-watt-hour battery to a 76-watt-hour battery. The new 13-inch models come with a 61-watt USB-C power adapter, whereas the 15-inch model includes an 87-watt USB-C power adapter. No more MagSafe, sorry!

The Massively Confusing MacBook Lineup — Remember the era of the Mac matrix, with a desktop and a laptop each for consumers and professionals? Those simple days of yesteryear are long gone, and it’s now impossible to keep track of Apple’s laptop line without a scorecard. That’s in part because the previous MacBook Pro models remain available, as do the 12-inch MacBook and the 13-inch MacBook Air. Apple did at least drop the 11-inch MacBook Air and the 2012 13-inch MacBook Pro that featured a SuperDrive but not a Retina display. That leaves us with the following list of machines, sorted by increasing base cost:

  • 13-inch MacBook Air (Early 2015): $999
  • 12-inch MacBook (Retina, Early 2016): $1299
  • 13-inch MacBook Pro (Retina, Early 2015): $1299
  • 13-inch MacBook Pro (Retina, Late 2016): $1499
  • 13-inch MacBook Pro (Touch Bar, Late 2016): $1799
  • 15-inch MacBook Pro (Retina, Mid 2015): $1999
  • 15-inch MacBook Pro (Touch Bar, Late 2016): $2399

The problem is that size, weight, performance, display quality, available upgrades, and other features see-saw across that list, creating a dizzying array of options for those who aren’t willing to just ante up to get one of the new MacBook Pro models. That’s the easy decision — these new models are the best at everything, and only a little larger and heavier than the underpowered 12-inch MacBook.

It’s hard to recommend any of the older models for any reason other than price, and even there it’s difficult, since their prices didn’t drop even after today’s release. Apple doesn’t generally compete on price, but it’s embarrassing to try to explain to someone why a nearly two-year-old 13-inch MacBook Pro still costs $1299.

Ordering — Both of the new MacBook Pro models are available in your choice of silver or space gray, the latter of which was previously an option only for the 12-inch MacBook. Those who are desperate for some MacBook Pro bling in gold or rose gold will be disappointed.

You can order all of the new MacBook Pros immediately, but Apple says the Touch Bar-equipped models won’t ship for two weeks.

We hope to have some personal experience with these new MacBook Pros soon, since the Touch Bar may feature heavily in the kind of documentation we write for TidBITS and Take Control. Plus, several TidBITS staffers have been waiting patiently for years for Apple to update the MacBook Pro line — it’s about time!
