Scheduling Multiple Different Power States

Scheduling Multiple Different Power States on a Global Scale

In today's interconnected world, managing power states for multiple devices across different platforms is a critical task. This article will explore the concept of scheduling multiple different power states on a global scale, focusing on the Mac's pmset tool and its features.

Understanding Power States

Power states refer to the different levels of power consumption that a device can operate in. These states range from fully on, where the device is running at full capacity, to completely off, where the device is not consuming any power. In between, there are various low-power states that a device can enter to conserve energy while still being able to perform certain tasks.

Scheduling power states is the process of automatically changing a device's power state at specific times or in response to certain events. This can be useful for a variety of reasons, such as conserving energy, reducing noise, or ensuring that devices are ready for use at specific times.

Scheduling Power States with pmset

The pmset tool is a command-line utility that is included with macOS. It allows users to view and change various power-related settings on their Mac, including scheduling power states.

To schedule multiple different power states with pmset, you can use the repeat flag. This flag allows you to specify a repeating schedule for a power state change. For example, the following command will wake the Mac at 9:00 AM every Monday:

You can also use the poweron flag to schedule a power state change that turns the Mac on. For example, the following command will turn the Mac on at 11:00 AM every Tuesday:

It is also possible to schedule multiple repeating power state changes at the same time. For example, the following command will wake the Mac at 9:00 AM every Monday and turn it off at 11:00 PM every Friday:

Troubleshooting Common Issues

When scheduling multiple different power states with pmset, there are a few common issues that you may encounter. One common issue is that the repeat flag does not support multiple power state changes at the same time. To work around this, you can create separate entries for each power state change.

Another common issue is that the pmset tool may not be able to wake the Mac from sleep or turn it on if it is completely powered off. To work around this, you can use the poweron flag to schedule a power state change that turns the Mac on, and then use the wake flag to schedule a power state change that wakes the Mac from sleep.
