Pushing to local from Mac doesn't work, but works on Linux

When I push to a device in local mode I can do it from my Linux pc just fine, it shows the build running and I can see the services come up on my Pi, but when I try to push exactly the same project from my Mac I just get

[Info]    Starting build on device

Both are running latest Balena CLI 13.3.1

Try with the --debug flag, see if it tells you any more.
