macOS is different in that /tmp isn’t actually on a tmpfs filesystem, but is rather just a normal directory on the main data volume that is cleaned on boot. One has to manually mount a tmpfs volume themselves with mount_tmpfs. Anyways, I’ll try the tarball linked and see if the issue still persists.
