Describe the solution you'd like
A clear and concise description of what you want to happen.
I have a powerful linux / windows machine that has a nice grunty GPU in it etc. As is typical of these machines, to run well they have lots of noisy fans - even if you use something like Noctua, it's still noisy. I also have a really modern apple silicon mac. it's really really quiet. It would be fantastic to get the best of both worlds by being able to run the backend that does all the GPU crunching on the linux machine and the frontend on the mac machine. This might already be possible, but I didn't see it in the guide and while the mac does connect to the linux machine's front end GUI, it complains that the backend isn't running - even though it is. I suspect not hard to make this feature happen.

Describe alternatives you've considered
Running it all on the mac. Assuming it uses the Mac's new GPU - it's still not as fast as the NVIDIA 4090 in my linux machine.

Just adding a note that also attempting to run it on a Mac, port 5000 is already in use as a default port in use for a few years now. Apparently it's airplay which could be disabled probably but of course I should be able to map a different port, but would be good to sort it out permanently in the build.

In case someone comes googling here, this was how I got it going.

Just an update the fix was ultimately to change in three places:

In docker compose.yml
ports:

• "5001:5001"
• APIPORT=5001
  Plus as per this thread: Avoid hardcoding the localhost variable in the source.  #95
  edit frontend/src/App/api/index.js
  and change const apiRoot = "http://localhost:5000/"; to const apiRoot = "http://localhost:5001/";

Then finally it works. This works well on a Mac.
