I've read that /var/folder is a temporary folder that survives reboot on MacOS.
I don't have a $TMP but I see
hom:~$ echo $TMPDIR /var/folders/g9/nm8_blpd5hx0vlhmc3x45h340000gn/T/
Other Mac users would likely have this problem, so I suggest a change in zim itself rather than me setting an environmental variable.
