Scheduling in Ventura has been removed. Here is the workaround.
I've been using the Scheduling feature of Energy Saver in previous OS versions to shut down my computer at night and start up in the morning so I was surprised that, even though Ventura has eliminated that feature, my computer continued to follow that schedule. The problem is I no longer have a way to change it or cancel it. But there is a simple solution. Here it is.
I learned from Apple Senior Support a work around that uses Terminal to access it.
Schedule your Mac to turn on or off in Terminal - Apple Support
The terminal command "pmset -g sched" revealed the current schedule. I was able to modify it as well as cancel it.
It works!
