Finder can't group file properly

So what are your View options set as.

Have you opened System Preferences> Spotlight> Search Results and made sure that Spotlight is set to include

images and movies in its search results. If they have not been indexed correctly then they may not display in the correct grouping.

How did you remove CleanMyMac, it is not enough just to delete the app, you have to uninstall it thoroughly,

get instructions from the developer.

Do you have any other third party apps installed that may stop the Finder from performing correctly.

As these forum pages are not cluttered with the same problem you are experiencing then it is most likely something that is unique to you and your set up. So if you have customised your mac out of the usual Finder preferences and view options

please tell us.

Click on View in the menubar and select Show View Options, from the panel that pops up

select how you want the files to be Grouped By, and then Sorted By.

Try a few combinations until you discover a combination that suits your preference.

Relaunch the Finder

Try relaunching the Finder. See if that fixes it:

Go To: Apple menu

Select: Force Quit...

Select: Finder

Click: "Relaunch Finder"

The Finder arranges files usually in Alphanumeric order, although it will selects all files that begin with a number at the top of the

column.

Your grouping looks fine to me. If you changed to column view in Finder, you should see that your files and folders are correctly arranged.

Your post more or less contains the answer in itself.

Since a clean install does not show the problem, and an update does, it stands to reason that something that you have installed affects how the Finder groups files.

Did you by any chance install er... "cleanmymac"? This hedious software appears every day on this forum associated with all sorts of problems.

Please run the diagnostic tool Etrecheck and post its report here so we can look for other possible causes.

It is "never" cleanmymac, but somehow it seems to always be there...

This hedious program has been hurting users left and right, and somehow continues to enlist more victims every day.

Also:

Gatekeeper disabled - Gatekeeper security protection is disabled. This computer is at risk of malware infection.

Apple security disabled - Apple security software is disabled. This computer is at risk of malware infection.

You disabling your mac's excellent built-in security and then compounding the damage by installing creepy software like "cmm"...

This program should never be allowed anywhere near your mac (or any mac). The first rule of keeping a sane mac is not to install junk.

Even if you uninstall this, there is no way to know the extent of the damage it may already caused. You could try uninstalling, and then maybe fixing things by rerunning the 10.15.3 Combo Update.

In the end, a clean install is probably in order.
