Amphetamine is a third-party application for macOS, designed to keep your Mac awake for a specified period or under certain conditions. It is not directly related to Apple's built-in systems or software development environments, but it can be useful for users who need to prevent their Mac from sleeping without altering the system's energy settings permanently.

Amphetamine is a versatile and user-friendly application that allows you to control when your Mac should stay awake. This can be particularly useful for tasks that require long periods of uninterrupted operation, such as downloading large files, running scripts, or performing system updates. Below, we will explore how to install and use Amphetamine on your Mac.

Examples:

1. Installing Amphetamine:

   • Open the Mac App Store.
   • In the search bar, type "Amphetamine."
   • Click on the "Get" button and then "Install" to download and install the application.

2. Using Amphetamine:

   • Once installed, launch Amphetamine from your Applications folder or Spotlight.
   • You will see an icon appear in your menu bar (a pill icon).
   • Click on the icon to access the menu.
   • Select "Indefinitely" to keep your Mac awake until you decide to turn it off.
   • Alternatively, choose "For a Duration" and specify the time period you want your Mac to stay awake.
   • You can also set conditions for activation, such as when a specific app is running or when a particular external display is connected.

3. Creating a Custom Trigger:

   • Click on the Amphetamine menu bar icon.
   • Select "Create New Trigger."
   • Define the conditions under which your Mac should stay awake, such as connecting to a specific Wi-Fi network or running a particular application.
   • Save the trigger, and it will automatically activate when the conditions are met.

4. Turning Off Amphetamine:

   • To stop Amphetamine from keeping your Mac awake, click on the menu bar icon and select "End Current Session."

While Amphetamine is a useful tool for managing your Mac's sleep settings, it is not an official Apple product, and its functionality is not integrated into Apple's software development environment. If you are looking for alternatives within the Apple ecosystem, you might consider using the built-in Energy Saver preferences in System Preferences to adjust your Mac's sleep settings manually.
