MacBook Air 11-inch (2014)

This MacBook Air 11-inch featured a 22-nm Haswell 1.4 GHz Intel Core i5 processor. It included 4 GB or 8 GB of memory and 128 GB or 256 GB of flash storage. This was the smallest of Apple’s MacBook Air line of laptops measuring 0.11 to 0.68 inches and weighed 2.3 pounds. It included a 720p FaceTime HD webcam, a backlit full-size keyboard, and an 11.6-inch widescreen TFT LED backlit active-matrix glossy display (1366×768).

Wireless connectivity included 802.11ac Wi-Fi and Bluetooth 4.0, while ports included analog audio out, one Thunderbolt port, and two USB 3.0 ports.

A previous version of the MacBook Air 11-inch nearly identical except for a slower processor and less available RAM and flash storage.

In my role as Assistant Superintendent for Technology & Innovation, I led the teams that managed nearly 4,500 of these laptops over a five-year period (2014–19). At the time, all high school students in the school district were issued a MacBook Air 11-inch and students used the same model for their 4-year high school career. Apple stopped manufacturing this laptop in 2018 and the high school switched to the iPad Generation 6.

HomePod (white, 2017)

Apple described the HomePod a “breakthrough wireless speaker for the home that delivers amazing audio quality.” HomePod can be controlled using Siri, “with an array of six microphones…users can interact with it from across the room, even while loud music is playing.”

HomePod’s features include an upward-facing woofer, a custom A8 chip, seven beam-forming tweeters (each with an independent amplifier), automatic room-sensing technology to optimize sound, and a six-microphone array with advanced echo cancellation. When Siri is in use, a multicolor waveform appears on the top of the HomePod using a round 272×340 display. In addition, touch controls are also available on the top of the HomePod.

The HomePod was available in white and space gray. Inside, the HomePod was powered by a 1.4 GHz Apple A8 processor and used 1 GB of RAM, 16 GB of storage, 802.11ac Wi-Fi, and Bluetooth 5.0.

The device runs an operating system that Apple refers to as audioOS (based upon iOS). The audioOS is specifically designed for the HomePod to play audio, run Siri, and control the custom round screen.

When the HomePod was announced in February 2018, multi-speaker support was demonstrated, but the feature was not released until September 2018 along with AirPlay 2. The September 2018 update also added support for multiple timers, Find my Phone, Siri short-cuts, phone calls (while in proximity to iPhone), and music search by lyrics.

I am a fan of the HomePod. I use two in my living room as my primary way of accessing Apple Music and controlling smart home devices. I also added a single HomePod to my bedroom.

Mac mini (Late 2014)

The Mac mini Late 2014 included a Core i5 “Haswell” 2.6 GHz Intel processor (with two independent cores on a single chip), 8 GB of SDRAM, and a 1 TB hard drive. Ports included two Thunderbolt 2 ports, four USB 3.0 ports, an HDMI port, Gigabit Ethernet, 802.11ac Wi-Fi/Bluetooth 4.0, and an SDXC card slot.

This and all Mac mini systems ship without a display, keyboard, or mouse. This model’s case is primarily aluminum with a black plastic back and base.

All Mac mini systems I have owned have served as my iTunes server allowing access to iTunes music/Apple Music, streaming video content, saved digital movies, and other media. This was the first Mac mini I owned with a direct HDMI connection to my primary home TV (others used VGA and DVI connections).
