Is it possible to use Home Assistant to automatically cause my iMac to login at a specific time?

By login, I mean to the user account on the iMac. I have a set of automations in Keyboard Maestro that will only run if a specific user is logged in.

If I could somehow get HA to log my user in automatically, then the KBM automations would fire off as expected.

A potential solution would simply be to reboot the computer remotely and then have Auto Login setup for that user.

The workstation is a shared production workstation in a church environment, and it would be nice to fire it up, have it logged in and ready to go when any number of triggers happen.

Ideas?
