Yes. The Apple M2 Pro (32GB) can run Qwen3.8 27B fully in unified memory at Q5_K_M (very good), using about 20.9 GB of the 21.4 GB available, at roughly 6 tokens/second.

Run it with Ollama

With Ollama installed, one command downloads and starts Qwen3.8 27B:

ollama run qwen3.8:27b

Ollama's default download is Q4_K_M (about 18 GB here). You have room for Q5_K_M, which is very good: pick that GGUF in LM Studio or from Hugging Face.
