Let's see, on Mac OS X (as this hardware is too old to run macOS) plus with myat
because I can never remember the date format at
wants...
$ date

$ myat 16:36
touch $HOME/nananananananananananananananana-atran
job 2 at Sun Nov 26 16:36:00 2017
$ atq

Uhhhh...maybe the man page for at
will help?
IMPLEMENTATION NOTES
Note that at is implemented through the launchd(8) daemon periodically
invoking atrun(8), which is disabled by default. See atrun(8) for infor-
mation about enabling atrun.
Meanwhile over in atrun(8)
we find...
Execute the following command as root to enable atrun:
launchctl load -w
/System/Library/LaunchDaemons/com.apple.atrun.plist
Gosh. Let's try that...
$ sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.atrun.plist
And then we wait like a minute or two...
$ atq
$ ls *atran
nananananananananananananananana-atran
$
Looks good once you turn it on (warning may drain battery or precious cpu slices...)
The CoreUtils package is also published as a Brew formulae. So if you have Brew installed you can also just run:
brew install coreutils
Then add PATH="/usr/local/opt/coreutils/libexec/gnubin:$PATH"
to ~/.bashrc
, run source ~/.bashrc
and you're done.
