According to Apple, the Apple Thunderbolt to Gigabit Ethernet Adapter “lets you easily connect to a high-performance Gigabit Ethernet network. Small and compact, it connects to the Thunderbolt port on your Mac computer and provides an RJ-45 port that supports 10/100/1000BASE-T networks.”
This adapter can be used with Apple computers with a Thunderbolt port, including MacBook Air (13-inch, Early 2015–2017), MacBook Air (11-inch, Early 2015), MacBook Pro (Retina, 13-inch, Late 2012–2015), MacBook Pro (Retina, 15-inch, Mid 2012–2015), iMac (Retina 4K, 21.5-inch, Late 2015), iMac (Retina 5K, 27-inch, Late 2014–2015), Mac Pro (Late 2013), and Mac mini (Late 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.
