No. Granite 4.2 30B does not fit on M2 8GB: Q4_K_M needs 20.1 GB and 5.4 GB is usable.
Hardware: M2 8GB · Model: Granite 4.2 30B
M2 8GB has 8 GB of unified memory and 100 GB/s of memory bandwidth. M3 8GB has the same memory and bandwidth, so the fit numbers match; this page is M2 8GB. The checker leaves macOS a share of unified memory, so Ollama can use 5.4 GB. Granite 4.2 30B (29.3B, IBM) at Q4_K_M is a 18 GB download and needs 20.1 GB with headroom for about 8k tokens.
