Usable shared or unified memory is the main blocker for this model.
Not enough usable memory
The model needs 23.5 GB, but this setup only exposes 17.3 GB of usable shared or unified memory.
Move to a larger memory pool
A larger unified-memory SKU or a discrete high-bandwidth GPU is the cleanest way to make this model practical.

No, Qwen 3 30B A3B requires more memory than MacBook Air M4 24GB provides.
Qwen 3 30B A3B (30.5B parameters) requires approximately 23.5 GB of memory with Q4_K_M quantization.
The recommended quantization for Qwen 3 30B A3B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Air M4 24GB, Qwen 3 30B A3B achieves approximately 11.1 tokens per second decode speed with a time-to-first-token of 17377ms using Q4_K_M quantization.
For coding workloads, Qwen 3 30B A3B on MacBook Air M4 24GB receives a F grade with 11.1 tok/s and 4K context.
On MacBook Air M4 24GB, Qwen 3 30B A3B can safely use up to 4K tokens of context. The model's official context limit is 131K, but available memory constrains the safe maximum.
Move to a larger memory pool. A larger unified-memory SKU or a discrete high-bandwidth GPU is the cleanest way to make this model practical.
Not always. MacBook Air M4 24GB can often fit larger models thanks to unified memory, but a discrete GPU with dedicated high-bandwidth VRAM may still decode faster once the model fits. For this combination, the important distinction is capacity versus sustained throughput.
