Throughout years of releases of Mac OS X and macOS, Apple provided a power-scheduling function within the Power Saver, Battery, or related locations throughout System Preferences. You might set a time of day on your Mac to start out up (or wake, if sleeping) or shut down. That point might be set to day by day, each weekday, each weekend day, or a given day of the week.
With the discharge of macOS 13 Ventura, the interface to these options disappeared. Had been too few customers making use of them? Had been they irrelevant with the present vitality effectivity of contemporary desktops and shows and the predominance of laptop computer gross sales? It’s unknown.
(In case you use a UPS, or uninterruptible energy provide, to offer emergency backup energy to your Mac within the occasion of an influence outage and have it related through USB to your Mac, the UPS settings stay out there by clicking UPS Choices in System Settings > Power Saver.)
This Ventura elimination ends in two situations for present Mac customers:
- In case you set a schedule earlier than upgrading to Ventura, it stays in impact however can’t be modified by way of the brand new System Settings.
- In case you have a cause to set a schedule of some form, you don’t have any apparent means to take action.
Apple happily solely eliminated the graphical consumer interface–it saved the underlying {hardware} function and help in place, accessible by way of the command line within the Terminal app, which is in Functions > Utilities. The command is known as pmset, and it requires “superuser” privileges to make modifications. (You have to be logged in to a macOS account that has administrator privileges lively. Terminal prompts you to enter the administrator password on your account after hitting Return following a superuser command.)
If you wish to filter a schedule you set earlier than Ventura, enter the next:
sudo pmset repeat cancel
This may increasingly cancel settings utilized by apps like Carbon Copy Cloner and different software program that may supply to wake your Mac to carry out backups and related actions. To test these schedules earlier than operating the above command, enter:
pmset -g sched
macOS gives an inventory of entries which will require interpretation. For instance:

Within the above, the listing exhibits upcoming occasions related to low-level information related to apps. com.bombich.ccchelper is a part of Bombich Software program’s Carbon Copy Cloner. com.getchannels.dvr is a part of the Channels DVR software program.
You’ll be able to set schedules from the command line, too. If you wish to allow a shutdown schedule, say Tuesday to Saturday at 11 pm:
sudo pmset repeat shutdown TWRFS 23:00:00
Within the above, the times of the week are clustered, and the time needs to be specified as a 24-hour clock entry. (The instrument has you set days of the week with the next capital letters: Monday, Tuesday, Wednesday, thuRsday, Friday, Saturday, and sUnday.)
At a Terminal immediate, you’ll be able to kind man pmset (or click on this hyperlink on a Mac) and skim additional particulars for extra elaborate schedules and settings.
