Run FME Desktop Workbench at a said date/hour on MacBook

For quick and easy solutions, you can use the Calendar app: http://osxdaily.com/2013/04/15/launch-file-app-scheduled-date-mac-os-x/

Then there's the Automator app for when you need more control, you can find lots of tutorials online and on youtube.

There's also crontab if you you're the hacker type, e.g. https://ole.michelsen.dk/blog/schedule-jobs-with-crontab-on-mac-osx.html

Finally there are some 3rd party tools (free and paid) that can do the same thing, you can probably find them using either Google or the App store.
