Note: This solution requires pstree to be installed from either MacPorts (sudo port install pstree) or Homebrew (brew install pstree) first. Show
To understand the relationship between processes, pstree is your friend. Without any switches it will show ALL processes. However, that produces quite some verbose output. To help narrow the search space for the issue, you can use the -u switch, to limit output to puke out only your own processes: pstree -u YourUserName I had high CPU activity and wanted to see what I did that was triggering it, so being able to see how processes were chained (spawned) was more interesting to me. Anyhoo, hope this helps you narrow to isolate the cause of a system issue quicker. If your Mac is slowing down or acting up, it may be because an application or program that’s running in the background is malfunctioning. If a task crashes or is taking up too many resources, you can kill it from the Activity Monitor. Here’s how: This
will force the process to quit, freeing up the resources it was using up. If this process is critical to your Mac, it will restart. If it’s an application, it will remain shut down until you reopen it. You can also force processes to quit from Terminal.
Easily remove startup processesOne common reason for Macs running slowly is that programs are launching automatically at startup. These can be helper apps for programs like iTunes or any variety of other apps. In some cases, they might be applications that are no longer needed. To review the apps and helpers that are launching on startup:
Keep your Mac running smoothly with CleanMyMac XCleanMyMac X’s Optimization module helps you keep your Mac running without being burdened by unnecessary background tasks. You can use it to easily disable and remove login items and launch agents. Download the app here. You can view and disable all launch agents from the Optimization section on the left sidebar. Each item has an Enable or Disable status next to it. Click to switch this status and turn the item on or off.
If you want to remove a login item or launch agent altogether, simply select the item and click Perform. You can’t undo this action, so make sure that you only disable an item if you might want to keep it as a launch agent in the future. Removing login items and shutting down background processes, will concentrate your Mac’s resources on the apps and processes you’re currently using. What application can you use to see all the active running Applications and processes on macOS 1 point?You can find out which programs and processes are running using an application utility called Activity Monitor. You can view every program, process and core system function that would otherwise remain hidden.
How do you see what Applications are running on Mac?Use the App Switcher to show open apps
The App Switcher is one of the most under-used and useful features in macOS. Hold down the Command key and press Tab. You will see a row of application icons appear in the middle of the screen. These are the apps that are currently running.
How do you see what is running in the background on Mac?To find the Activity Monitor, you can navigate to your Applications and find it within the Utilities section. A faster way to find it is to simply hit Command + Spacebar and type in Activity Monitor, where Spotlight will automatically find the utility.
