macOS flamenco worker test fails: blender_cmd […] does not exist

Question

so I fire up the flamenco worker in test mode, it registers at the manager (yay!) and then I send a test job. Here's what comes next:

I think the important part is the first warning in line 4... I've read a couple of times that this path that "blender_cmd" wants to use tends not to work, but how can I change it (I've tried editing $PATH and .profile) and is that the issue at all?

Turns out you have to set the path to the blender binary of the workers in the setup of the manager! Switch the manager to setup mode, add the path to your blender binary (not the .app) and I set that binary to 'worker' only and added another one for 'user' only that points to the .app.
