In the Apple ecosystem, particularly on macOS, the concept of "Suspensão Automática de Apps" (Automatic App Suspension) typically refers to the system's ability to manage app resources efficiently, especially when they are not actively in use. This feature is crucial for optimizing system performance and conserving battery life. However, macOS does not have a direct equivalent to some of the more granular app suspension features found in other operating systems. Instead, macOS relies on a combination of app nap, memory management, and power management techniques.

In this article, we will explore how to leverage macOS's built-in features to achieve similar outcomes to automatic app suspension. We will cover how to use App Nap, Activity Monitor, and Terminal commands to manage and monitor app performance.

Examples:

1. Using App Nap: App Nap is a macOS feature that automatically reduces the resources used by apps that are not actively in use. To ensure an app can take advantage of App Nap:

   • Open the Finder and navigate to the Applications folder.
   • Right-click on the app you want to manage and select "Get Info."
   • In the Info window, ensure that the "Prevent App Nap" checkbox is unchecked. This allows macOS to manage the app's resource usage when it's in the background.

2. Monitoring App Performance with Activity Monitor: Activity Monitor is a built-in macOS utility that provides detailed information about the system's resource usage.

   • Open Activity Monitor from the Applications > Utilities folder.
   • In Activity Monitor, you can view which apps are using the most CPU, memory, energy, disk, and network resources.
   • To manage an app, select it from the list and click the "i" button to get more information or use the "Quit" button to terminate it if necessary.

3. Using Terminal Commands: For more advanced users, Terminal commands can be used to manage and monitor app performance. For example, you can use the pmset command to adjust power management settings.

   # Check the current power management settings
   pmset -g
   
   # Enable power nap (similar to App Nap but for the entire system)
   sudo pmset -a powernap 1
   
   # Disable power nap
   sudo pmset -a powernap 0

   Additionally, you can use the top command to monitor real-time system performance:

   top -o cpu

   This command sorts running processes by CPU usage, helping you identify which apps are consuming the most resources.
