The Dock Normally, when you right-click on a running application in the OS X Dock, you see an option to “Quit.” This may not work with a frozen app, however. To force quit an app, hold the Option key on your keyboard while you right-click on the app’s Dock icon and you’ll see that “Quit” is now “Force Quit.” Click it to force quit the app. Be sure to note that there’s no warning when you force quit an app, and that the usual “save” prompts don’t appear before the app is closed. Therefore, be careful when you make your selection, and double check to ensure you’re force quitting the correct frozen app.

If you accidentally force quit an app you’re working in, you’ll lose any unsaved data or changes. The Force Quit Window OS X has a special window dedicated to handling apps that need to be force quit. You can access this window two ways, first, by clicking the Apple logo in the Menu Bar and selecting Force Quit. Alternatively, you can bring up this same window by using the keyboard shortcut Command-Option-Escape. The window will display all running applications, and identify with red text any apps that are “not responding.” Just highlight an app and click the Force Quit button to quit it. As mentioned above, there’s no warning when you force quit an app, so be careful as you make your selection.
Activity Monitor The Activity Monitor app offers a wealth of information about the current status of your Mac, its resources, and your applications, but it also allows you to force quit any frozen apps. Just locate the app in the processes list ( hint: you can use the search box in the upper-right portion of the window to filter the list), select it to highlight it, and then press the X button in the upper-left part of the window. You’ll be presented with two options: Quit and Force Quit. If possible, try Quit first, as this will attempt to gracefully quit the application and preserve user data. If that fails, use Force Quit, which will act the same way as the steps mentioned above.
The ‘Kill’ Command in Terminal If you prefer a command line method to dealing with unresponsive apps, you can use the ‘kill’ command in Terminal. To use this method, you’ll need to determine the app’s (PID), a numeric value that OS X uses to keep track of each unique application.
The easiest way to find an app’s PID is via Activity Monitor, where it will be listed in the PID column. If you’re using Activity Monitor to find the PID, however, you might as well use it to force quit the app, as described previously. Instead, you can use the ‘top’ command to generate a list of running processes right in Terminal.
You can use modifiers to order the list by user-defined criteria. If your app is frozen, there’s a good chance that it’s eating up CPU resources, so a good sorting method to start with is ‘cpu.’ Open a new Terminal window and type the following command: top -o cpu A list of all running applications and processes will appear in Terminal, ordered by current CPU usage. Let’s use iTunes as the example. It’s listed at the top (because it’s currently consuming CPU resources) and its process ID is 5472 (note: PIDs are unique to each circumstance, and OS X generates a new PID each time an application is run.
That means that the PID will change each time an app is launched, and it’s almost certain that iTunes on your own Mac will have a different PID). With the process ID now identified, press Q to quit top, or open a new Terminal session, and type the following to force quit the app: kill PID In our iTunes example, we’d type: kill 5472 Press Return to execute the command and your app will be force quit. Keyboard Shortcut You can directly force quit an app via a keyboard shortcut, without any of the intervening steps mentioned in the previous methods above.
This may therefore seem to be the best and most obvious method, but there’s a reason it’s listed here last. Using the keyboard shortcut below will immediately force quit the active, or foremost, application. The problem is that it’s very easy to lose track of which app is active, especially when dealing one or more frozen or unresponsive apps. Therefore, this method is the most risky from a data loss perspective, as it’s far more likely that a user will make a mistake and inadvertently force quit the wrong app.
But, if you understand this risk and are careful, this force quit shortcut is the fastest method. To use it, make sure the frozen app is active and press and hold Command-Option-Shift-Escape (you’ll notice that this is simply the Force Quit Window shortcut with the Shift key modifier thrown in). As with other force quit methods, the active application will immediately be force quit.
Sometimes hardware issues or major OS X bugs cause so much instability that the only way to get your Mac up and running again is to reboot. Absent those rare circumstances, however, you should be easily able to control any frozen or misbehaving apps by force quitting them via one of the methods above. Just be sure to save your work when possible, and double-check your steps to avoid quitting the wrong app. Want news and tips from TekRevue delivered directly to your inbox?

Hello, My Macbook Pro suddenly shut down and is not turning on, no chime, no apple logo. There was no exposure to water.
(However, I had kept a steaming bowl of hot water right next to the laptop.But this was in an open kitchen) The Pro had less than 10% charge when it suddenly shut down. I charged it for another 10 minutes and tried to switch on, but no luck. I charged it completely till the magsafe indicator turned green, still does not turn on.
So assumed that the battery is charging fine. I opened the mac and saw no visible corrosion or moisture(two tiny dots below the battery case are white and haven't turned red) I have tried the following already. SMC reset - With the magsafe adapter connected, when I do the reset the charge indicator turns green from orange. Disconnected and reconnected the battery connector - still no life. Its been only a year and three months I bought this in India. Could the logic board die out so soon?
How to pinpoint if it is indeed the logic board? Thanks a lot! When trying to attempt to boot it, press the trackpad. If it clicks, the MacBook is coming on (but is not displaying picture, chiming or another issue), if not, the MacBook is completely dead, which will be an issue with the logic board. The force touch trackpads will only click when the MacBook is on, so this is a good indicator when diagnosing these. Remove the logic board and check it for any liquid damage. Remove the tape at the top of the board (this covers components, sometimes liquid is underneath this.
Clean any liquid with 95%+ isopropyl, but before cleaning, take a picture for reference, so we know what area was affected by the liquid (if the clean doesn't resolve the issues. The MacBook should boot when the battery is reconnected and the charger plugged in, so there is clearly an issue with the logic board. Reset the SMC on Mac notebook computers First, determine whether the battery is removable. Mac notebook computers that have a nonremovable battery include MacBook Pro (Early 2009) and later, all models of MacBook Air, MacBook (Late 2009), and MacBook (Retina, 12-inch, Early 2015) and later. Learn more about Mac notebook batteries. If the battery is nonremovable: Shut down your Mac. Unplug the MagSafe or USB-C power adapter from your computer.
Using the built-in keyboard, press Shift-Control-Option on the left side of the keyboard, then press the power button at the same time. Hold these keys and the power button for 10 seconds. Release all keys. Reconnect the power adapter. Press the power button again to turn on your Mac.
If the battery is removable: Shut down your Mac. Disconnect the MagSafe power adapter from your computer. Remove the battery. (Learn about removing the battery in MacBook and MacBook Pro computers.) Press and hold the power button for 5 seconds.
Reconnect the battery and MagSafe power adapter. Press the power button to turn on your Mac. The LED on MagSafe power adapters might change colors or temporarily turn off when you reset the SMC.
Reset the SMC on Mac desktop computers Follow these steps for iMac, Mac mini, Mac Pro, and Xserve. Shut down your Mac. Unplug the power cord. Wait 15 seconds.
Plug the power cord back in. Wait five seconds, then press the power button to turn on your Mac. Thanks Varun. My solution: use right (more powerful 85 watt) power adapter.
I tried all of the above after my MacBook Pro 15” (mid 2102) died as I was working last night. I am in Montreal on a business trip, and fortunately there is an Apple Store two blocks away that opened at 8 this morning.
Turns out I brought a 65 watt charger with me. My battery at 100% is now just 43% of original, and got to 0% charge—so wouldn’t boot up on the 65 watt charger. It did resurrect at the Apple Store on an 85 watt charger. The store didn’t have one in stock, but very helpfully looked up that there were three 85 watt chargers in stock at the local Staples store (in French called “Bureau in Gros,” which I’m guessing translates to “Wholesale Office.” Anyway, be sure you brought the right charger if your battery is old.
