Yes. Granite 4.2 30B fits in fast memory on M1 Max (32c GPU) 64GB at Q8_0 (33.1 GB needed, 48.0 GB usable), about 10 tok/s (estimate).
Hardware: M1 Max (32c GPU) 64GB · Model: Granite 4.2 30B
M1 Max (32c GPU) 64GB has 64 GB of unified memory and 400 GB/s of memory bandwidth. M2 Max (30c GPU) 64GB and M2 Max (38c GPU) 64GB and M3 Max (40c GPU) 64GB have the same memory and bandwidth, so the fit numbers match; this page is M1 Max (32c GPU) 64GB. The checker leaves macOS a share of unified memory, so Ollama can use 48.0 GB. Granite 4.2 30B (29.3B, IBM) at Q8_0 is a 31 GB download and needs 33.1 GB with headroom for about 8k tokens.
