'ensd' process on Activity monitor

I experienced the same problem too. After checking the "Sample" of the process, it is revealed that it is related to the EaseUS Data Recovery or similar app (which I actually uninstalled long time ago) and there is still a zombie process eating resources.

To solve the problem, this process needs to be completely removed by removing all EaseUS folder at /Users/<Username>/Library/Application Support/EaseUS

There's this process that shows up on my Activity monitor - and whenever it's on, it kills my battery (and makes my laptop overheat)! I got this MacBook less than 2 weeks ago, and have installed nothing on it, mainly only use it for school. Apps I have are very basic ones such as Spotify and Opera. What does this process mean?? Should I be concerned!? How should I get rid of it? Whenever I quit it - it reappears not long later!

I've searched a lot about this, but can't find a thing!

Do you use Citrix ...(?)

Run the "Sample" and see what insight to the process you can gain...

Alternatively —To trouble shoot further you can:

—Try a SafeBoot https://support.apple.com/en-us/HT201262

Takes noticeable longer to get to the login screen, does a 5 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc.

Login and test. Reboot as normal and test. Caches get rebuilt automatically.

In Safe mode third party system modifications and system accelerations are disabled, it removes malware, etc hampering smooth operation, however a reboot will put it back to normal mode.

This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.

—Test issue in another user (or guest user) account https://support.apple.com/guide/mac-help/set-up-other-users-on-your-mac-mtusr001/mac

This will tell you if it a universal issue or isolated to your user/admin account. 

Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus

You like me and almost everyone who uses Monterey has the dreaded memory leak bug.  Apple will fix it eventually.

Before then there is a simple temporary solution.  Presumably you have several desktops on your mac.  I have 11 at the moment.  Go to one you don’t use often and open up Activity Monitor(its in your applications and on every mac).  Leave it open all the time.  Click on the column that tells you the use of memory by system processes and apps.  Highlight(click on) any that look completely out of control, and then click on the little icon with the x in the middle of a circle.  Choose force quit. If its an app it will quit and you will have to restart it.  If its a process(weird names mostly) then it will quit but come back almost instantly in the small size it's supposed to be.  For me about 15 minutes ago I noticed that the most common culprit, Control Center(which normally uses about 26 mb of memory)  was slowly sucking more and was up to 144mb.  Earlier this week I found it at 14 GB.  

You can keep these little buggers from stealing memory by just keeping an eye on them.  Be advised:  if WindowServer is up at 1gb then its probably doing it too, and if you force quit that one, your screen will go black for about 5 seconds while the OS puts it back, and then you will have to type in your machine password again.

Hope this helps.
