cpu usage

Hi


I recently updated to OS Catalina on my desktop-my system has at times slowed way down, and I am hoping that someone here can give me an idea of what the problem might be.


Here is a shot of my cpu usage.


Any help will be appreciated.


Thanks

Nothing of significance shown in what you have posted. If you are using AM to identify something eating up CPU time and slowing the computer, then you need to leave it open while using the computer normally. If a slowdown occurs, then look at the AM display to identify any app that is causing the slowdown. It may simply be Spotlight indexing the drive or Time Machine involved in a backup.


Use Activity Monitor to Kill Runaway Processes


     Use Activity Monitor on your Mac

     Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity.


You could download EtreCheck Pro 6.1.4 and use it to try and identify the problem, if any. There is a free version available.

  9. Avoid using any third-party cleanup software. Usually, this software does more bad than good. You don't need it. All computers become slower over time even under normal use. Experienced users erase the hard drive and do a clean install from scratch from time to time; or whenever installing a major OS upgrade. Doing so means you must maintain regular and multiple backups.
  10. If you have enabled iCloud Disk and are storing your Documents and Data in iCloud, then consider turning that off and signing out of iCloud. It can slow down the computer considerably.
