Qwen 3.5 9B is a 9.65B-parameter model. At Q4_K_M it needs about 6.4 GB of memory. The MacBook M4 Pro 24GB has 18 GB usable, so it fits entirely in memory. Expect about 23 tokens/sec (19–26), with the first token after 0.5 s for a short prompt. This estimate is projected from the hardware specs; no benchmarks exist yet.
