Infatti, se sui computer troviamo un sistema operativo vero e proprio ( principalmente linux, windows o mac ), sugli embedded no ( anche se, come vedremo in un altro post, esistono le versioni per embedded di linux e windows ). Date le scarse risorse hardware a disposizione, si preferisce creare un software specifico, cercando di rendere il. To respect user freedom and truly protect user security, manufacturers must either allow computer owners to disable the boot restrictions, or provide a sure-fire way for them to install and run a free software operating system of their choice.

Knowing which Apps or Processes are running on your Mac is important, because some of these Apps could be slowing down your Mac. You will find below 4 different ways to show All the Running Apps and Processes on your Mac.
Why to See All Running Apps and Processes on Mac
In case you are coming from a Windows computer, you must be used to opening the Task Manager on your Windows computer, in order to take a look at all the running apps and processes on your computer.
In the case of a Mac, there are multiple ways to see all the Running Apps and Programs, ranging from the simple option of using the Dock to using the Terminal command.
In general, the purpose of taking a look at All the Running Apps and Programs on your Mac is to get an idea of which programs are actively running on your Mac, what resources they are using and also to rule out the possibility of any unnecessary programs running in the background and using up resources on your computer.
Show All Running Apps and Processes On Mac Using the Activity Monitor on Mac
Activity Monitor can be described as the Mac equivalent of a Task Manager in a Windows computer. The Activity Monitor provides a very good view of the App and processes running on your Mac and the amount of resources being uses by these Apps and Processes.
1. Click on the Finder icon located in the left corner of the Dock (See image below)
2. On the next screen, click on Applications in the left sidebar menu and then click on the Utilities Simple pong (jackboyman) mac os. folder.
3. In the Utilities folder, click on Activity Monitor which should be the first item in Utilities Folder (See image below)
4. Once Activity Monitor opens, you will be able see a list of All the Processes or Applications currently running on your Mac (See image below)
As you can see in the above image, there are 5 different tabs in the Activity Monitor -> CPU, Memory, Energy, Disk and Network. Merged mac os.
Clicking on each tab will show you more details, for example, clicking on the Memory Tab will show you how much memory each process is using. Similarly, clicking on the CPU tab will show you the amount of CPU being used by each of these Apps and Processes running on your Mac.
5. To view more info about a specific Process or Application, simply click on the Application/Process and then click on the i icon button located at the top left Corner of the screen (See image below).
6. To force quit an application or process through Activity Monitor, simply click on the application you would like to force quit and then click on the x button, located at the top left side of your screen (See image below)
Show All Running Apps On Mac Using Force Quit Applications Manager
Another method to check all the Running apps and programs on your Mac is through the Force Quit applications manager on Mac.
1. Click on the Apple icon in the top menu bar of your Mac and then click on Force Quit Application in the drop-down menu (See image below).
2. This will open the Force Quit Applications manager which will show you all running apps on your Mac
3. To force quit one of these applications, simply click on the application from the list and click on the Force Quit button.
Show Running Apps and Processes On Mac using the Terminal Command
The Terminal also shows you a detailed view of which applications and processes are running on your Mac, along with the percentage of CPU used by each of these applications/processes.

2. Next double click on the Terminal option or press the enter key on your Mac’s keyboard to open up Terminal
3. In the terminal type in top –o cpu and press the enter key on your keyboard
This will show you a list of all running apps and processes with the apps consuming the most CPU at the top of the list.
4. To reorganize this list close the Terminal and reopen it. Once Terminal reopens type in top –o rsize and press the enter key on your keyboard.
Now applications or processes which are using the most memory will be listed at the top of the list and the application or processes using the least memory will be listed at the bottom of the list.

The easiest way to view running apps on your Mac is by simply taking a look at your dock.
All running applications will have a black dot underneath the applications icon (See image below)
