About the MacBook Air 13" M4 (16 GB)

The MacBook Air 13" M4 is a mid-range 16 GB laptop: it runs 9B models at 13 tok/s. Among 16 GB machines, only the M1 Pro, M2 Pro and M5 write faster. macOS keeps about 3.5 GB, leaving 12.5 GB for models. Prompt reading is its weak spot: a 4K-token prompt waits 57 s before the first word on Qwen3.5 9B. At its $999 MSRP it gives 13.2 tok/s per $1,000, 5th of the 7 machines compared here. M4 generation, released 2025; the newer M5 writes 28% faster with 1.9× the compute.
