The tiny chip on the left is a DS2413 1-Wire Dual Channel Addressable Switch. Two identical LEDs are on the other side. In the middle are two LEDs, orange/red and green. The circuit board inside the Magsafe connector is very small, as you can see below. The block of metal on the left is not magnetized, but is attracted by the strong magnet in the Mac's connector. The plastic pieces hold the pins in place. There is no data communication via the adapter sense pin with the charger unit itself.ĭisassembling the connector shows the spring-loaded " Pogo pins" that form the physical connection to the Mac.

Only two wires - power and ground - go to the charger unit. The charger wires are soldered onto the back of this board. Removing the outer plastic shell reveals a block of soft waxy plastic, maybe polyethylene, that helps diffuse the light from the LEDs and protects the circuit underneath.Ĭutting through the soft plastic block reveals a circuit board, protected by a thin clear plastic coating.

Also note that the middle adapter sense pin is much smaller than the pins, unlike the Magsafe 2. The connector below is an older Magsafe notice the slightly different shape compared to the Magsafe 2 above. I had a Magsafe cable that malfunctioned, burning the power pins as you can see in the photo below, so I figured I'd tear it down and see what's inside. The pins are arranged symmetrically, so the connector can be plugged in either way. There is a Touch ID button on the upper right of the keyboard, just like on the previous MacBook Pro models but it has a circular ring, like on the iMac keyboard.The pins of a Magsafe 2 connector. These Function keys aren’t half-height keys-they’re full-sized. Apple seems to have been persuaded by the users who don’t like the Touch Bar, because it’s gone in the new M1 Pro MacBook Pro, replaced by Function keys. MacBook Pro: No more Touch BarĪpple introduced the Touch Bar in 2016 to replace the function keys with “a brilliant, Retina-quality Multi-Touch display,” but it has been a divisive feature, to say the least-those who dislike it are quite expressive about it, while people who like it don’t really say much (at least it seems that way). The headphone jack also has support for high-impedance headphones. And if you are using the laptop with the new third-gen AirPods, AirPods Pro, or AirPods Max, there is spatial audio with dynamic head tracking.Īpple calls the built-in three-mic array “studio quality” and they have a high signal-to-noise ratio and directional beamforming. The speakers also have support for spatial audio when playing music or video with Dolby Atmos. Apple has made the notch the same depth as the menu bar so it won’t intrude on your workspace.Īpple offers the MacBook Pro in two colors, Silver and Space Gray. The top of the display has a notch for the FaceTime camera, just like the iPhone. The bezel (the border around the display) has been greatly reduced, so much so that the MacBook Pro logo is no longer at the bottom on the screen-it’s on the bottom on the laptop. The 14-inch MacBook Pro is 0.61 inches tall and weighs 3.5 pounds, while the 16-inch model is 0.66 inches tall and 4.7 pounds. The new 14- and 16-inch MacBook Pros feature a new aluminum case design that makes the laptop smaller than previous models. The displays also support the P3 color gamut and True Tone. The 14-inch model has a native resolution of 3024-by-1964 at 254 pixels per inch, while the 16-inch version has a native resolution of 3456‑by‑2234 at 254 pixels per inch. And yes, that is a notch for the FaceTime camera.Īpple’s specs for the display include a 1,000,000:1 contrast ratio, 1,000 nits of full‑screen brightness and 1,600 nits of peak brightness. The displays on the MacBook Pro have a 120Hz refresh rate.
