Force Open An App On Mac
Ok, I get it. There is no equivalent to the PC’s Ctrl+Alt+Del shortcut on a Mac® to force quit an application. So how do I quit that annoying program that’s not responding?
Right-click on the app and hover over Options in the menu. Apps that are set to open automatically will have a check mark next to Open at Login. Tap that option to uncheck it and disable it from. (If you click the icon of an app that isn't currently running, it will open.) You can shut down an app directly from the dock by right- (or Ctrl-) clicking the icon and selecting Quit. While the Mac is a little more open than iOS - the only way to get third party apps onto your iPhone and iPad is to download them from the iOS App Store - there are still a lot of hoops to jump.
Luckily, Apple® has you covered and gives you multiple options. The shortcut actually exists, and moreover, there are a few other extremely convenient ways to fight buggy apps. Today I’m going to list three easy ways to force-quit an application on a Mac, without harming the system.
Force Open Apps On Mac
Let’s dive in!
Is it Safe to Force Quit?
Forcing a frozen application to quit is the same as killing the symptoms when we get sick versus curing the virus. We need to see the bigger picture and understand what causes the problem and how to cure it while understanding how to avoid it from happening again.
The number one reason we have a problem with frozen applications in a Mac is insufficient RAM—or, in other words, a lack of computer memory to operate the system compared to the number of applications you usually open (including those numerous open tabs in a browser). So anytime your system utilizes all of its existing resourses to run the task, it becomes unresponsive. Think of RAM like a physical workbench. The more space (memory) you have to work, the more projects you can have out to work on. Less space? Less ability to work on multiple things at once.
Forcing Mac to quit the application does resolve the problem but may have downsides. When you close an application in the traditional manner, it will clean everything it runs in the background and alert you to save the work. When you force close on Mac, you may end up losing files and data, or mess things up on the drive. Although the effect will only be related to that one particular application that got stuck, sometimes it can hurt.
Next, click on the unresponsive App in the Application Manager and then click on the blue Force Quit button to close the unresponsive app. Depending on the App that you are quitting, you may see a pop-up asking to confirm that you do want to Force Quit the App. Tap on the blue Force Quit button to quit from the unresponsive App. Force Quit Apps On Mac Using Apple Menu Bar. I either use the force quit menu or just click the app in the dock with th right button, press opt and then click force quit. See all replies Force Quit Mac Applications With the Keyboard.

1. Force Quit Using the Apple Menu
The most conventional and effective way to close frozen programs is to go to the macOS® menu bar, located along the top of the screen in the Finder menu.
To force quit an application, simply do the following:
- Click on the black apple icon in the upper-left corner.
- From the drop-down menu, select “Force Quit…”. You will be directed to the new window named “Force Quit Application” where all the magic happens.
- Now all you have to do is select the application you want to close and choose “Force Quit.”
If you don’t know which application is stuck, pay attention to the ones that have the note “Not Responding.” This usually appears next to frozen applications.
2. Force Quit with Mac Shortcut
To do the same thing but faster, use Mac shortcut keys to close frozen applications.
- On your keyboard, press and hold Command + Option + Esc. It will immediately bring up a “Force Quit Application” window.
- Select the frozen application from the dialogue box and select “Force Quit.”
This could be your go-to method if the mouse or trackpad is lagging.
3. Close Application from Activity Monitor (Ctrl+Alt+Del Alternative)
Here’s the pinnacle of this article. /cbc-music-app-mac.html.
Very few Apple owners know that macOS provides an almost identical alternative to the traditional PC Control+Alt+Delete shortcut—and does it better. Yes, we all know that in Windows that keyboard shortcut is often used to open the Task Manager window. (To be honest, it’s needed too often, which is why we’re on a Mac.) From Task Manager, you can track applications, services, performance, and processes, and kill some of them when they’re unresponsive.
You can easily do all of that and more on the macOS native application called Activity Monitor.
To kill an application using Activity Monitor, do the following. Best calendar app mac 2016.

3. Once Activity Monitor is highlighted, hit Enter.
4. In the Activity Monitor processes list, select the application you want to quit and click “Force a process to quit” in the left corner.
What to Do If Force Quit Isn’t Working?
If all the applications stop responding and you can’t quit them using one of the methods described above, you can force your Mac to restart. To do so, press and hold the Control+Command+Power buttons.
Alternatively, you can force Mac to shut down by pressing and holding the power button, or use one of the many other shortcuts.
What’s the Solution?
Can't Open App On Mac
Since your Mac doesn’t have enough space to run all those applications you need, the most obvious step would be to increase the RAM. If you own an iMac® or the older generation of MacBook Pro®, you can simply buy memory and upgrade your existing computer. With the new Mac generation, you don’t have that option anymore because the RAM is glued and soldered to the motherboard. You either buy a new computer or struggle.
Alternatively, you can clean your memory to free up space using Parallels® Toolbox. Parallels designed a tool set for macOS and PC users to efficiently manage their computer with just a few clicks—without any professional knowledge needed. Within the application (which is available to try for free), you can easily free up unused computer memory, clean your drive, and help your Mac run at max speed with a dozen other useful utilities.

So there you have it. Take care of your Mac with those quick tips, and remember to always save your work!
Starting with OS X Mountain Lion, Apple introduced Gatekeeper so users couldn’t easily install downloaded apps from outside the Mac App Store.
When someone downloads an app from somewhere other than the Mac App Store they will get one of a few warning messages depending on what security settings they’ve set in System Preferences. We’ll show users how to set the security settings in Security & Privacy section of the OS X System Preferences using any version of OS X after Mountain Lion so they can install downloaded apps from outside the Mac App Store.
Why Can’t I Install 3rd-Party Apps By Default?
If you don’t care about why this works, skip to the next section. Here’s why Apple sets OS X to disallow 3rd-party apps by default, for those who like to understand why things work as they do.
Cynics will say that Apple does this because they don’t get a 30% cut from applications bought directly from third-party apps instead of their curated app store. A $10 app nets Apple $3 and the developer gets only $7. The developer gets the entire $10 if the app is sold directly.
Apple says they set things blocking third-party apps because they want to protect users who might install downloaded apps with malware or viruses. They take the 30% cut to cover the cost of hosting the Mac App Store and testing apps to keep malware out of the store. In other words, they want to help protect us from our own mistakes.
Apple offers three setting options in the Security & Privacy Settings in System Preferences. Apple set the default to help protect users from Malware or to lock down computers depending on which explanation you prefer.
Apple created Gatekeeper, a program to protect users from Malware. Developers can get a security certificate from Apple through the Apple Developer program. If a developer distributes their app on the Mac App Store, they have to follow certain guidelines to get approved. These guidelines try to keep malware out of the store. Developers can also add a security certificate to their apps. The certificate is some code inserted into the app code. Users can set their machines to allow third-party apps downloaded from the Internet, but only if they include one of these security certificates.
Find out how to change the settings below so you can install downloaded apps from trusted third-party websites. Don’t install apps from just any site because relaxing security settings could potentially open the door to malware and viruses.
How to Install Apps from Outside the Mac App Store
To install third-party apps, the user must change a setting in the Security & Privacy section of System Preferences, the Settings app in OS X.
Open OS X System Preferences by clicking on the app icon from OS X Dock or by clicking the Apple icon in the Menu Bar in the upper left corner of the screen. When the menu pops up, click on System Preferences.
Click on Security & Privacy from the top row of the System Preferences app. Choose the General tab to see the settings below.
There’s a lock icon at the bottom of the dialog box. Click it to enable all the settings in the box. The OS will ask the user to enter their administrator’s password. Click OK and the grayed out settings become clickable.
The settings we need to work with show up at the bottom half of the dialog box. There are three options under Allow apps downloaded from:. Here are the descriptions taken from Apple’s support site.

- Mac App Store – Only apps that came from the Mac App Store can open.
- Mac App Store and identified developers (default in OS X) – Only allow apps that came from the Mac App Store and developers using Gatekeeper can open.
- Anywhere – Allow applications to run regardless of their source on the Internet (default in OS X Lion v10.7.5); Gatekeeper is effectively turned off. Note: Developer ID-signed apps that have been inappropriately altered will not open, even with this option selected.
If the user chooses the first two options, they can close the dialog box and continue. However, if the user chooses Anywhere, the above warning pops up to scare the user from using this setting. It says:
Choosing “Anywhere” makes your Mac less secure.
The warning box explains that OS X resets this setting after 30 days. Users will have to come back here and do the above steps again. Further, it explains that it’s safer to let the OS warn you each time you launch an app, which includes an option to allow it by clicking an OK button if you select the middle option of the three.
Which Option Should You Choose?
Those who only install apps from the Mac App Store should not bother changing the default settings. Make sure to select the first option labelled Mac App Store and close the box. If you want to install and run any app you want and don’t worry at all about malware, then choose the third option labelled Anywhere. I use the second option since I can still install third-party apps, but they have to come from developers who take the time to add an Apple Developer security certificate to their app. These are safe, but can come from outside the Mac App Store.
