How does an app in Apple’s MAC system force it to quit?


When the application response speed is too slow, you can use force exit to close the window

Windows users can use Ctrl + Alt + delete to force windows to close, but OS X Yosemite’s operating system is very stable, although sometimes when the application program stops working, users also need to force exit. Here we will introduce several methods to force the application to close. You can use the forced exit command or restart the computer directly.

Method 1: use the force exit button in the dock menu bar

Enter the dock menu bar at the bottom of the screen, find the icon of the application to be closed, press and hold the right mouse button (or click the mouse while holding down the CTRL) to pop up the menu bar, and then click the last exit option, and then the general application will be closed. If not, perform the second operation, but remember to press and hold the ALT key when the menu bar pops up to exit The option will be forced exit. If you click force exit, the application will be forced to close immediately.

Method 2: use the forced exit key

Now let’s introduce two other methods to use the forced exit command. The first method is to click the apple icon at the top left of the screen, and select the last forced exit option from the drop-down list. The second method: press and hold the command + Alt + ESC three keys, the pop-up window will display all the running applications, and the unresponsive app will show no response. Select the application to be closed, click the forced exit at the bottom of the window, and then re run the program to check whether it can work normally

Method 3: what to do when the application is unresponsive and unable to perform other operations?

In some cases, when the application does not respond and cannot leave the program for the above forced exit, press and hold the four keys of CMD + Alt + Shift + ESC to close the OS X program.

Method 4: use activity monitor

If you want to find out where the system is running wrong, you can use the built-in activity monitor, click to enter finder, find applications > utilities > activity monitor in the navigation bar, open the activity monitor, and all running applications will be displayed, including the amount occupied by each software CPU, memory, network and other data information. If you double-click an application program, an independent window will pop up to display more relevant information and current status of the current application. Users can choose After sampling, you will get the activity report of this program for a period of time. However, this program is too specialized, and many users may not understand it. Therefore, we will introduce a more practical method of forced exit.

Method 5: what to do when the computer system is out of control?

In some cases, the failure of an application may cause the whole computer system to lose control, but the probability of this situation is relatively small. For most users, the only way to solve this problem may be to select the power button. After pressing the power button, a message will pop up on the screen asking whether to confirm the forced shutdown, and then the system will automatically enter the sleep state. If you press the power button for a long time, a window will pop up, displaying the options of “restart, sleep, shutdown”. However, in the case of a serious system crash, these options may not be displayed, so the last solution is to press and hold the power button until the computer is completely powered off, although this method can allow users to restart and recover Mac, but due to the sudden termination of the computer may cause some data loss, in this case, this is the only way to get the computer back to work.
