Apple 13-inch MacBook Air M4 vs Apple MacBook Air 13-inch (M4)

These are the same 13-inch MacBook Air with the M4 chip, so the real decision is configuration and condition, not the model. The silver MW0X3LL/A pairs 16GB of memory with a 512GB SSD and is new, which suits most buyers. The other listing is a certified pre-owned unit with a 256GB SSD and battery health of 85% or better, so it only makes sense if you want to spend less and can live with half the storage and a used battery. Owners and reviewers consistently praise the M4 Air's silent fanless design, long battery life and light 2.7 lb body; the main complaints are the two-port limit and the lack of a touchscreen.

• Choose the Apple 13-inch MacBook Air M4 512GB if you want a new machine with double the storage and a fresh battery, and you keep large photo, video or app libraries.
• Choose the MacBook Air (2025) M4 256GB if you mainly browse, write and stream, want to spend less, and are comfortable with a certified pre-owned unit whose battery is rated at 85% health or better.
