This means macOS is aware the application is having problems. Happily, you can force quit such applications just as easily as any other: just select it, then click Force Quit. When an application is not responding, you can also force quit it using the Dock. Just right-click the icon and you’ll see that “Force Quit” has replaced “Quit.”. Best one note like apps for macs. Why force quit might not work in the first place. A lot of the time, this can happen when an app isn’t well built. When this happens, all kinds of havoc can be wreaked on your hardware that makes it tough for your Mac to process the tools necessary to force quit an app. Memory leaks can be a big source of these kinds of issues. Normally, if you want to close all of the open apps on your Mac, you'd have to either quit them all one by one or restart, shut down, or log out while making sure to deselect “Reopen windows when logging back in.' The latter option is great, but it doesn't always work in Mac OS X, and what if you don't want to restart, shut down, or log out? Whether MacOS is giving you a spinning beach ball of death or a particular app is taking too long to close, sometimes you just need to immediately close an app and get back to work.
Activity Monitor User Guide
You can use Activity Monitor to quit a process, even if it’s in a loop or not responding. You can also send a signal to a process to terminate it. If you attempt to quit a process you don’t own, you may be required to authenticate as an administrator.
- In the Activity Monitor app on your Mac, under the Process Name list, select the app or process you want to quit. An unresponsive process is marked with (Not Responding).Note: The Process Name list is not available in the Cache page.
- Click the Force Quit button in the upper-left corner of the Activity Monitor window (or use the Touch Bar).
- Choose one of the following options:
- Quit: This is the same as choosing File > Quit within an app. The process quits when it’s safe to do so. If quitting the process could cause data loss or interfere with another app, the process doesn’t quit.
- Force Quit: The process quits immediately. If the process has files open, you may lose data. If the process is used by other apps or processes, those apps or processes could experience problems.To see if a process is used by another process, choose View > All Processes, Hierarchically.
To send a signal to a process, select it in the process list, choose View > Send Signal to Process, choose a signal from the pop-up menu, then click Send.
If you’re the sort who likes to keep on top of the apps running on your system, then you’ve probably already encountered those stubborn processes that, despite quitting the application, keep behind-the-scenes core or periphery application processes running in the background, consuming processing power and draining your battery. Or, out of the blue, the Mac slows down because one of these processes start to run, suddenly eating up 100% of the CPU. Ending this process will improve the overall performance of the computer, especially in systems with less RAM.
Then there are things like removable media and mounted disk images, where processes hidden from plain view could well prevent the media from safely ejecting. This is a situation that no doubt everyone has encountered at least a few times…

How to View Processes
There are various ways to view running apps and processes in macOS: looking at the Dock, opening the Force Quit Applications window, using the Terminal, and finally by checking Activity Monitor. Also, certain third party Mac monitoring apps, such as iStat Menus, can allow you to view the processes by clicking on the CPU icon in the menu bar.
Activity Monitor, the built-in system monitoring utility, is the best way to view all processes currently running on the Mac, and from here manage them based on how they affect the computer's performance. Using the ‘view’ menu allows users to choose which processes are shown in each of the five categories, be that all processes hierarchically, user processes, system processes, active processes, and more.
The Most Common Processes Mac Users Complain About
Spotlight
At the core of every search performed on a Mac is Spotlight. Whenever you search for a file, it is Spotlight that will locate it for you, because it indexes the contents of the computer. Think of situations such as migrating to a new Mac, after a complete system erase and new install, a major macOS upgrade, and the like. In these cases Spotlight will consume a lot of your computer's computing power. There are situations where it's not important to have a fully indexed Mac, and at these times it makes sense to disable Spotlight to save resources.
Faces, Memories, Photos

Pdf reader apps sync mac ipad. Indexing faces and objects was promoted by Apple as one of the key features of the Photos app and macOS Sierra. While in theory it is a nice feature, in actual fact it became a source of frustration because users couldn't understand why it took so long to index the photo library. Some users had huge photo libraries, others smaller, but the result was the same slow indexing process. According to Apple support, the ‘feature’ has a daily limit on the number of photos it is able to process.
That’s the photoanalysisd process, which sometimes launches and demands CPU resources. As a result, what you'll notice is a slow Mac that can become hot if the process takes too long to run.
What Processes to Kill With Activity Monitor
When you open Activity Monitor, a long list of items appears. When looking at the process names, the vast majority of them may sound like gibberish to you, and you'll be tempted to kill all of them. That won’t always be such a good idea, though, so it is important to ask yourself: ‘Which processes do I need to kill?’
- Look for processes with names similar to those of closed apps. It's safe to quit processes that resemble app names you have already quit.
- Close Rosetta applications. These are PowerPC processes running on an Intel-based Mac, so it doesn't make too much sense to allow them to eat into the physical resources of your Mac.
- Quit disk image processes. Sometimes the only way to unmount a stubborn disk image is by killing the associated disk image process.
- Quit processes using high amounts of CPU. In the CPU tab click on the arrow until it is facing downwards. This will help you identify the processes that are demanding high CPU resources.
- Kill all duplicate processes by clicking on the Process Name tab to view the processes in alphabetical order, and quit any secondary items with the exact same name.
Please note that there are some processes that shouldn’t be messed with, especially those run by the root user. If you are not certain what a process means, it is better to ask for help from someone who does or contact Apple support.
