Trying this out and trying to pre-boot the simulator with the macOS orb seems too have broken with this update:
jq: error (at :2862): Cannot iterate over null (null)
Exited with code exit status 5
EDIT - turns out I needed to update my OS version to 26.1, rather than 26.0, but the above error is a bit cryptic.
@lukeredpath got it. let us know if you run into any other issues.
