Mac mini M4 Pro (64 GB / 1 TB) — for sale
I have some new purchases planned for the AI home lab, so Zebra — the lab’s always-on Mac mini — is for sale. It is an M4 Pro with the maximum 64 GB of unified memory, a 1 TB SSD and 10 Gigabit Ethernet, bought new from Apple in February 2026 and still covered by AppleCare+ until 2 March 2029.
It has been running as a 24/7 local model server. It is quiet, sips power, and is still one of the nicest small machines for local inference on Apple silicon. The 64 GB of memory and 10 GbE are both build-to-order options — 64 GB is the maximum Apple offered in the M4 Pro mini, and 10 GbE was a paid upgrade.
Why it is interesting
The 64 GB of unified memory is the point. The GPU can address the whole pool, so this machine comfortably runs models that would not fit on a typical 8 GB or 16 GB graphics card. It currently serves Gemma-4-31B-it Q4_K_M around the clock with a 131,072-token context, and it can also join a larger machine as an RPC worker when a model needs more memory than either host has alone.
It is also a very good general-purpose Mac: fast CPU, three Thunderbolt 5 ports, 10 GbE, and very little fan noise.

Purchase and warranty
- Bought new from Apple on 7 February 2026; single owner.
- Original configuration: M4 Pro 14-core CPU / 20-core GPU / 16-core Neural Engine, 64 GB unified memory, 1 TB SSD and 10 Gigabit Ethernet.
- Original Apple price: CA$3,649, plus CA$119 for AppleCare+.
- AppleCare+ for Mac mini (M4) is active until 2 March 2029. Full details, including the agreement number and proof of coverage, will be made available on sale; I can help transfer the plan to the buyer.
What it runs today
- llama.cpp 0.6.0-dev (build 132, Metal) serving Gemma-4-31B-it Q4_K_M (17 GB) 24/7.
- 999 GPU layers, flash attention, batch 1024 / ubatch 512, 131,072-token context, alias
gemma-4-31bon port18080. - Managed by a LaunchAgent so it comes back after a reboot.
- The local model cache also carries Qwen3.8-27B and Qwen3-30B-A3B Q4_K_M.
- Can act as an RPC worker alongside another llama.cpp host for larger models.
The model cache will be cleared as part of the wipe, so treat the software stack as a demonstration rather than part of the sale.

Headless GUI access
An HDMI dummy plug is included if you want it. With the plug fitted, macOS keeps a virtual display active while the Mac mini runs headless, so you can connect to the full desktop over VNC rather than being limited to SSH.
Condition and what is included
- Single owner, bought new in February 2026. Fully working, no known faults; it has been running continuously as a lab server.
- Sold erased and signed out of iCloud, with macOS reinstalled and ready for setup.
- Original Accessory Kit and power cable included.
- Can be inspected and tested in Vancouver by arrangement.
