Overview

The following provides an introduction to Processes. We will cover the following topics:

  1. Requirements
    Prerequisites to successfully complete this tutorial.
  2. Monitoring processes and applications
    Explaining how to efficiently monitor processes and applications.
  3. Suspending, resuming and quitting processes and applications
    Explaining how to control processes and applications in Processes.

Requirements

Before starting this tutorial, make sure you have the following items available:

  • Latest version of Processes
  • Mac OS X 10.6 or higher

Monitoring processes and applications

When you open Processes for the first time you will notice that Processes' interface is divided into four major parts:

  • Process List
  • System Overview
  • Selected process open files or network connections
  • Selected process detailed information and controls

Process List

The Process List is dominated by a table which contains rows describing processes or apps and all of their pertinent information.

Displaying processes by user

Since OS X runs plenty of processes (daemons, helpers, etc.), you can choose which processes to be displayed in the process list by user.

This way you considerably lower the number of processes to display.

You can display all processes and apps, the current user’s all processes, the current user’s apps only, root processes and other processes not owned by the current user or by root.

Sorting

By default Processes sorts the list by Process Id, however you can sort the list by any other column, by simply by clicking on the header of the desired column.

The columns which contain text will be sorted alphabetically, while the columns containing numeral values will be sorted in decreasing order.

Filtering

While you monitor the running processes, you can always filter by keyword, this way the Process List will be filled only with processes or apps matching your keyword.

Right-Click Menu

By right-clicking on a process in the Process List a menu full of options will appear for the clicked process or app.

  • You can Activate all windows for the selected app (apps only).
  • You can Reveal In Finder the executable of the app or the precess itself.
  • You can Suspend or Resume the selected process or app.
  • You can Force Quit the selected process or app.
  • You can Restart the selected app (apps only).

Note: The right-click menu also provides general options (not related to the right-clicked process) such as Resume All Processes and Reopen All Force Quitted Apps.

Resume All Processes

This option will resume all suspended processes.

Reopen All Force Quitted Apps

This option will open all the applications force quitted by Processes in the last 20 minutes.

System Overview

Cette section de Processes fournit des informations détaillées en temps réel sur l'utilisation des ressources de votre système.

The graphics are updated every second.

Selected process' open files and network connections

1. Open files

The Open Files table contains all files accessed by the selected application.

You can sort the table by clicking on its header.

You can also double-click on a selected file to reveal its location in the Finder.

2. Network connections

The Network connections table contains information about the currently selected process or app’s network connections such as:

  • The IP type
  • The protocol used
  • The server’s IP address and port number
  • The connection’s status

Suspending, resuming and quitting processes and applications

Selected process' detailed information and controls

In the selected process' detailed information and controls section of Processes you can suspend, resume and force quit processes and applications.

Suspend

By clicking on the suspend button you can suspend any process which can be suspended. Please note that some processes cannot be suspended for OS X’s stability and safety.

Resume

Suspended processes can be resumed individually, by clicking on the resume button , or in batch by selection the Resume All Processes option.

The Resume All Processes option can be found in Processes the tools menu or by right-clicking on any process in the Process List.

Force Quit

Processes and applications can be stopped (force quitted) if they are not responding for instance. The stopped processes or apps can all be reopened later on (within 20 minutes of them being force quitted) using the option Reopen All Force Quitted Apps located in Processes the tools menu or by right-clicking on any process in the Process List.

Restart

There are two options to restart applications:

1. Use the Restart option which can be found in Processes the tools menu

2. Right-click on any process in the Process List.

Warning: The Restart option actually kills the app or process, then it relaunches it, therefore the restarted process will have a new Process Id (PID).
