Only just. Qwen3 32B fits on the Apple M2 Pro (32GB) at Q3_K_M, which costs noticeable quality. Expect about 7 tokens/second. A card with more memory is a better experience.

Run it with Ollama

Ollama's default qwen3:32b download is Q4_K_M, which needs about 22.6 GB, more than the 21.4 GB available. Download the Q3_K_M GGUF instead (LM Studio lists quants per model), or try a smaller context length.
