Set up render machines and ComfyUI on Mac

Renders run on ComfyUI, on This Mac or on servers on your network. Choose Merrimo > Settings (⌘,) and click Rendering to choose which machines Merrimo uses and in what order.

Show me how: Set up render machines and ComfyUI ↗
Settings ▸ Rendering showing Render Machines with This Mac and Mac Studio, Share with Collaborators, and This Mac status and network addresses.
Settings > Rendering lists your Render Machines in priority order, collaborator sharing switches, and This Mac’s status and network addresses.

Add a render machine

  1. Click + next to Render Machines.
  2. To add a ComfyUI server, choose Add Server…, enter its address (such as http://192.168.1.10:8188) and a name, and click Add. If This Mac isn't listed yet, the menu also offers Add This Mac.
  3. Click Test on a server's row to check that Merrimo can reach it. Each row shows whether the machine is Online, Starting, Offline or Off.

Choose the order

Each render goes to the first free machine in the list. Drag a machine onto another to move it there. Turn a machine's switch off to stop using it without removing it, or choose Remove from its ⋯ menu.

Use This Mac from another Mac

Under This Mac, you see its status, with Restart, and the addresses other Macs can reach it at. Click Copy next to one, and add it as a server in the other Mac's Render Machines list.

To lend a machine to the people you write stories with, see Render on a collaborator's machine on Mac.


Open the ComfyUI tools window

Open ComfyUI on your render machine directly from Merrimo:

  1. Choose Tools > ComfyUI… (or press ⇧⌘N).
  2. The ComfyUI interface opens in a dedicated window, allowing you to inspect workflows, custom nodes, and sampler queues.
