Background
Apple introduced the 15" (technically 15.3") MacBook Air at WWDC in June 2023 as a larger option within the MacBook Air line, marking the first time Apple's offered a laptop larger than 13" apart from their Pro lineup. The laptop is essentially a scaled-up version of the 13-inch MacBook Air from 2022, sharing design language with it and its 14 and 16-inch siblings. The 2023 model sports an M2 Apple silicon SoC and starts at $1299.
Apple has a nifty tool available if you need help identifying your MacBook Air.
