Macs have "unified memory" meaning the GPU uses the same memory as the CPU and minis can have up to 64 gigs. So its a lot faster than running on a CPU and a lot cheaper than any other GPU based rig with similar memory.
Everyone recommending a Mac Mini for OpenClaw is recommending the base model (which has just 16GB of ram), so it’s not about the unified memory, it is about the agent being able to interact with your apple ecosystem services like reminders, iMessage etc.
It is the cheapest Mac you can get for that.
It allows your Claw to access all your iCloud data easily like reminders and iMessage for example
Mac’s are still pretty terrible at running LLMs. They will be there someday, but that isn’t today
Unified Memory and Integrated GPU.
Apple is amazing at marketing to make 1990s technology sound cutting edge. I'm sure they change something for plausible deniability, as a nominalist, not even 2 of the same computers are the same.
Most openclaw users are not running the models locally.
