Balena preload failing on macOS

[chriswiggins]

Expected Behavior

Preload command works successfully

Actual Behavior

Running preload with an image (and optionally a splash image) fails when hitting the clean up temporary files task:

Command: DEBUG=1 balena preload balena-cloud-nz-broadcast-intel-nuc-2.113.4-v14.9.1-preload.img --fleet <SLUG> --splash-image splash.png

Error: An error has occurred executing internal preload command 'preload':
