...Through online investigation I found out that this process is related to the notification center. I want this process to not utilize most of my memory and if it comes down to disabling the notification center, I am totally ok with it. I've exhausted all of my energy to troubleshooting this process, I found very few "solutions" that are just simply old and do not work anymore....

Some of those articles are pretty old, so not sure if the advice that worked then on the older version of the OS will work for you. did you try these hints? Or was there some other troubleshooting that you tried and did not work?

Delete thesefiles & restart...

~/Library/LaunchAgents/com.adobe.ccxprocess.plist

/Library/LaunchAgents/com.adobe.AdobeCreativeCloud.plist

~ tilde indicates hidden Home Library.

Apple hid the Users' Library folders...

Method 1:

1 From the Finder, select the Go menu at top of the screen, and choose Go to Folder.

2 In the window that opens, enter ~/Library, and click Go.

Usernoted is a process that is responsible for notifications on OS X.

Be very careful with Terminal & hard to see spaces...

Open the Library folder in your Home folder.

In the Library folder, open the Application Support folder.

Locate the folder named NotificationCenter. Drag this folder to the desktop.

Next, open the Terminal application. Copy and paste each line of these commands into the Terminal window, in order. Press return after each line:

cd `getconf DARWIN_USER_DIR`

rm -rf com.apple.notificationcenter

killall usernoted; killall NotificationCenter

Close the Terminal app.

Restart your computer.

Maybe some other app is using the Notification Center and not playing nice with it. Check for any login items, try disabling all of them, and adding them back in one at a time. You can find those in System Preferences/Users & Groups/Login Items.

If you are not sure where those login items are, right click on them to reveal them in Finder, so you can find them to add them back later.

The Notification Center is something built into the mac OS, but other apps that use it to report messages may be causing the problem, one idea is to check for apps that start automatically at login that may be running in the background that you might not be aware of.

OH, to find stuff Apple thinks we're too dumb to handle, & sometimes we are, but...

Find Any File...

Hold Option or alt key when selecting Find to Find All.

Completely uninstall CleanMyMac. It alone could be the cause of your problems.
