Another way is to use the man pages in Terminal. This can be the fastest and easiest way to find out about a particular process. There are a couple of options for looking up more information about processes you find. Mac Running Slow, Noisy Fan: accountsd High CPU Usage.KernelManagerd Causing High CPU Usage & Battery Drain.If they are causing you trouble, see the following articles for more information on dealing with these: These processes are daemons, programs that run in the background waiting for a service request (generally, processes ending in ‘d’ are daemons) KernelManagerd deals with kernel extensions, and accountsd deals with external accounts in apps. Not everyone will have the same set of processes running even for processes that everyone has running on their Mac (like kernel_task), they won’t be using the same level of resources on different Macs or at different times on the same Mac.Ī couple of processes that have been known to cause problems in the past are KernelManagerd and accountsd. There are many processes running on your Mac at a given time. Often you will see root or your own user name.įor more details about Activity Monitor and the information you can find there, see Activity Monitor: What It Is & How To Use It (Task Manager).

The information available in Activity MonitorĪlthough there is a lot of information available in Activity Monitor, we’ll stick to a few parts you are likely to find useful. Search – If you know the name of the process you want to find, you can type it here, and then you’ll only see information for that process.Tabs – When you select one of the following tabs, you’ll get more information about how processes are using that resource:.Info – The ‘ i‘ in the circle will show you more information about a selected process.Quit – The circle with an X in it is used to quit a selected process.At the top of the windowĪt the top of the Activity Monitor window, you will find a few buttons, tabs and a search bar.
