The last time Apple had a third MacBook in the lineup was the 12-inch model from 2015. Rather than an entry-level option, however, it was positioned as a more advanced, ultra-thin device, costing more than the MacBook Air at the time. That model was discontinued in 2019.
The 13-inch MacBook Air starts at $1,099 and the 15-inch model starts at $1,299. They are available in sky blue, midnight, starlight, and silver. The Air now also starts with 512GB of storage, doubling the base capacity of the previous model.
