We never like to have problems with our computers, right? However, some of them are inevitable. Sometimes your apps don't work, your Mac gets slow, you see a spinning wheel of death, and more. Understanding the root of some problems can be difficult; fortunately, there are some troubleshooting tools to diagnose what's wrong with your Mac.
One such tool is the Activity Monitor, and in this article, we'll tell you how to use it, what alternatives are out there, and how to maintain your Mac to avoid different problems. So let's start!
Activity Monitor — The Task Manager for Mac
If you're familiar with the Windows Task Manager, then you may wonder whether there is a twin for Mac. Don't worry, a Task Manager exists on Macs, but it has another name — Activity Monitor. Just keep in mind that Activity Monitor is the Mac Task Manager equivalent and functions in a very similar way as it does in Windows.
Activity Monitor shows the processes running on your computer, so you can see how they affect your Mac's performance. This important tool will help you manage your Mac's activity, so you should know how to use it at its full potential.
How to open Task Manager on Mac
Activity Monitor is located in the /Applications/Utilities/ folder, and there are a few ways to launch it. The simplest one is to use Spotlight for a quick search.
Here's how to access Task Manager on Mac using the Spotlight:
- Press Command+Spacebar to get the Spotlight search field.
- Start typing 'Activity Monitor.'
- Select the Activity Monitor when it comes up. This will take you to the app.
However, if Spotlight doesn't work or you just want to try another way to open Task Manager Mac, do the following:
- Click on the Finder icon in the Dock.
- Choose Applications from the side menu of the window that appears.
- In the Applications folder, select the Utilities folder and open it.
- Double-click on the Activity Monitor icon to launch it.
The good news, you can avoid the long ways of opening a Task Manager by pinning it to the Dock. Once you do it, you'll be able to access the Activity Monitor by simply clicking on its icon.
Follow these steps, and you won't keep asking yourself how to start Task Manager on Mac every time you need to check some processes:
- Open the Activity Monitor using one of the ways described above.
- Right-click on the Activity Monitor icon in the Dock.
- In the menu, choose Options and then click Keep in Dock.
That's it! The Activity Monitor will be available from the Dock of your Mac, so you can view it easily.
How to use the Activity Monitor
The Activity Monitor is a simple but very important tool. Find out what you can do with its help.
Monitor the system parameters
The Path Of Energy Mac Os 7
Once you open the Activity Monitor on your Mac, you'll get access to the five tabs: CPU, Memory, Energy, Disk, and Network. By analyzing the data, you can identify what processes affect your Mac performance.
- The CPU pane shows how processes are affecting the processor activity.
- The Memory pane shows how the RAM is used by apps on your Mac.
- Tap on the Energy pane, and you'll see the overall energy use and the energy used by each app.
- The Disk pane shows the amount of data that each process has read from your disk and has written to it.
- Use the Network pane to identify which processes send and receive the most data.
View additional info about an app or process
The Mac Task Manager also allows you to check the additional information about every application or process on your Mac. Here's how to view it:
- Click on the application or process you're interested in.
- Click on the 'i' button in the top left corner of the Activity Monitor window.
- You'll see a pop-up window showing additional information about an app or process.
As you see, the Activity Monitor is a real gem. It helps you gain insight into many useful things. Momo the horror game (itch) mac os. Therefore, it will be much easier to diagnose any problem your Mac has.
How to Force Quit applications from a Task Manager in Mac
If some application or program freezes and you can't quit it, you can use the Activity Monitor to shut it down. To force quit an app from a Mac Task Manager, do the following:
- Open the Activity Monitor on your Mac and click on the application you want to force quit.
- Then click on the X button in the top left corner of the Activity Monitor window.
- You will see a pop-up window asking if you want to quit this process.
- Click Quit to close the unresponsive app.
- If the app is still open, choose Force Quit to end the process immediately.
What's a Control+Alt+Delete equivalent on Mac?
All Windows users know this magic combination: Control+Alt+Delete. The first thing they do when an app or program hangs is using this keyboard shortcut. Fear not: there's the similar shortcut for Macs.
In addition to the Activity Monitor, Macs have a Force Quit Applications Manager that allows to close the frozen apps and programs. To open it, hold down the Command+Option+Escape keys.
If you just need to force quit an application and don't care how much CPU or Energy it is using, then you should launch a Force Quit Applications Manager to perform the task. It gives immediate access to all apps, so you can quickly fix an unresponsive program.

The default layout for installed Haskell components follows the conventions of most unix-like systems. On Mac OS X, this layout isn't optimal, and a different layout is used. The layout presented here has several advantages:
- Follows Apple's Guidelines for file system layout
- Makes it easy for a user to locate all the Haskell components, especially user installed packages
- Enables easy removal of a user installed package, whether they have installed it --user or --global.
- Facilitate creation of unified, hyper-linked Haddock documentation, optionally with source
Haskell Platform 2011.2.0.0 (March 2011) and later uses this layout and sets up cabal to use it for built packages. On new installs, if you didn't already have a ~/.cabal/config file, then it is set up by default. Otherwise, the config file for this layout is placed in ~/.cabal/config.platform and you can manually move it over, or incorporate it into your existing config file.
Implementations
Haskell implementations are generally installed for use by all accounts on thesystem. They consist of large collections of executables, libraries, and otherfiles. These are packaged using Apple's framework, versioning, and bundlingtechniques and installed in:
For example, GHC 7.0.2 is installed in:
Executables intended for use from the command line, are be symlink'd into:
[Q: Would /usr/local/bin be more appropriate? ]
Packages that come with the implementation, are be located within the Frameworkbundle.
If the implementation has any GUI applications, these are installed in:
NB: These guidelines allow for multiple implementations and multipleversions to co-exist. (With the exception of multiple versions of GUI applicationswhich can only be done by distinct naming, and the symlinks in /usr/binwhich can achieved in the normal way: Append the version number to the executableand then symlink the 'bare' name to the most recent.
If implementations want to be able to be installed 'per user', then the abovepaths should be:
Not all software for Mac OS X offers a 'per user' option on installation, and whilenice, it is by no means universal.
User Installed Packages
User installed packages are placed under a 'prefix' that depends on if the userchoose to install for all users (--global) for just their own use (--user):
Package Component Layout
Cabal offers a large amount of flexibility in where the various pieces of a packageare installed. The GHC package system is rather agnostic about where these pieces are,and insulates the implementation from such differences. These combine to enable thechoice of package layout to be largely to serve the user.
For both --global and --user installs, this is the recommended package layout on Mac OS X:
This can be achieved with the following cabal configuration defaults:
N.B.:
- Cabal configuration files don't actually support ~. You must replace that with /Users/xxx where xxx is your account name.
- All packages for a given compiler are under a single directory. When an old compiler is removed, all the packages compiled for it can be easily removed too.
- All components for a package are under a single directory. This facilitates easy location and removal of a single package, for either a single compiler, or all installed versions.
- If a package generates different doc for different compilers (it may have different APIs available), then this structure preserves each.
- Executables are also per compilation, which is sometimes important (for Haddock, for example).
Executables
Packages that build executables to be run from the command line present a difficultly. They are built into a per-package bin directory, and then should be symlink'd somewhere on the user's PATH. For global installs, the logical place is one of:
For user installs, since ~/bin is not on the PATH by default on Mac OS X and may not exist, binaries are symlink'd into:
Alas, cabal only supports one location for both kinds of build, and so it is set to be the later.
