Where the memory goes
| Component | Detail | GB |
|---|---|---|
| Model weights | Q2_0 GGUF (0.5 GB) + mmap overhead | 0.5 |
| KV cache | 4K context window | 0.1 |
| Runtime | macOS inference app + compute buffers | 0.8 |
| Total needed | Q2_0, 4K context | 1.4 |
| Working budget | 8 GB unified memory − conservative macOS reserve | 5 |
| Headroom | remaining inside the working budget | 3.6 |

Get it running on this Mac
This Mac has enough memory, but the tracked Q2_0 ternary file is not supported by the current point-and-click apps. For a first local chat, use Bonsai 27B 1-bit in Locally AI. Do not download PQ2_0; the publisher marks it unsupported.
The advanced path is complete below, but it is not required for ordinary local AI.
Advanced publisher setup (Terminal)
Install Apple's command-line tools if macOS asks, then run:
git clone https://github.com/PrismML-Eng/Bonsai-demo.git
cd Bonsai-demo
BONSAI_OPENWEBUI=0 BONSAI_SKIP_MLX=1 BONSAI_FAMILY=ternary BONSAI_MODEL=1.7B ./setup.sh
BONSAI_FAMILY=ternary BONSAI_MODEL=1.7B BONSAI_CTX=4096 ./scripts/start_llama_server.shWhen the server says it is ready, open http://localhost:8080. Start with 4K context. This route uses the publisher's Prism runtime, not Jan or LM Studio.
