Apr 07, 2017 But not every Mac app is signed. Some apps available on the web–particularly older ones–just aren’t signed, even if they’re trustworthy. Maybe they haven’t been updated in a while, or maybe the developer just didn’t bother. That’s why Apple offers a way to bypass Gatekeeper. (You may also want to bypass this and run an unsigned.

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 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.
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)

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.
1. To open Terminal on your Mac, do a spotlight search for the Terminal by pressing the Command + Space keys on your Mac keyboard and searching for Terminal in Spotlight Search. (See image below)
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.
Show Running Apps Through Dock
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)
While this method is easy to follow, it sometimes will not show you all apps running in the background and does not even show you which processes are running in the background.
This method also does not give you much detail, like how much memory each application is using or how much CPU is being used by each application.
The safest place to get apps for your Mac is the App Store. Apple reviews each app in the App Store before it’s accepted and signs it to ensure that it hasn’t been tampered with or altered. If there’s ever a problem with an app, Apple can quickly remove it from the store.
If you download and install apps from the internet or directly from a developer, macOS continues to protect your Mac. When you install Mac apps, plug-ins, and installer packages from outside the App Store, macOS checks the Developer ID signature to verify that the software is from an identified developer and that it has not been altered. By default, macOS Catalina also requires software to be notarized, so you can be confident that the software you run on your Mac doesn't contain known malware. Before opening downloaded software for the first time, macOS requests your approval to make sure you aren’t misled into running software you didn’t expect.
Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy.
View the app security settings on your Mac
By default, the security and privacy preferences of your Mac are set to allow apps from the App Store and identified developers. For additional security, you can chose to allow only apps from the App Store.
In System Preferences, click Security & Privacy, then click General. Click the lock and enter your password to make changes. Select App Store under the header “Allow apps downloaded from.”
Open a developer-signed or notarized app
Mac Verify App
If your Mac is set to allow apps from the App Store and identified developers, the first time that you launch a new app, your Mac asks if you’re sure you want to open it.
Why Does Mac Verify Apps Free
An app that has been notarized by Apple indicates that Apple checked it for malicious software and none was detected:
Prior to macOS Catalina, opening an app that hasn't been notarized shows a yellow warning icon and asks if you're sure you want to open it:
If you see a warning message and can’t install an app
If you have set your Mac to allow apps only from the App Store and you try to install an app from elsewhere, your Mac will say that the app can't be opened because it was not downloaded from the App Store.*
If your Mac is set to allow apps from the App Store and identified developers, and you try to install an app that isn’t signed by an identified developer or—in macOS Catalina—notarized by Apple, you also see a warning that the app cannot be opened.
If you see this warning, it means that the app was not notarized, and Apple could not scan the app for known malicious software.
You may want to look for an updated version of the app in the App Store or look for an alternative app.

If macOS detects a malicious app
If macOS detects that an app has malicious content, it will notify you when you try to open it and ask you to move it to the Trash.
How to open an app that hasn’t been notarized or is from an unidentified developer
How To Verify Mac Os
Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy. If you’re certain that an app you want to install is from a trustworthy source and hasn’t been tampered with, you can temporarily override your Mac security settings to open it.
In macOS Catalina and macOS Mojave, when an app fails to install because it hasn’t been notarized or is from an unidentified developer, it will appear in System Preferences > Security & Privacy, under the General tab. Click Open Anyway to confirm your intent to open or install the app.
The warning prompt reappears, and you can click Open.*
The app is now saved as an exception to your security settings, and you can open it in the future by double-clicking it, just as you can any authorized app.
