It's been over six months since Apple launched the M4 chip in the iPad Pro on May 7, 2024. Since then, the M4 chip has also made its way into the MacBook Pro, but has yet to arrive on the MacBook Air.
In 2020, the MacBook Air was one of the first three machines to make the switch from Intel processors to Apple Silicon in the form of the M1 chip. In 2022, it was joined by an M2 model.
