Applying sharing and permissions privileges takes a long time, trying to change the EDID profile. (Dell U2410)

[bugnish]

I need to connect my Mac book pro to my Dell U2410 monitor. The problem began when realize that the computer does not recognize RGB data properly from monitor. I search on internet to solve this issue and I found a way to override and force the RGB data to being understandable to my computer by an EDID file. On Youtube I found a way to do this.

On the tutorial, the youtuber explains how to create a file in system/library/displays/contents/resources/overrides
to create a profile to solve the RGB data problem. But on my Mac I could not copy the file to the folder, so I try to apply sharing and permissions privileges to this folder system/library/displays/contents/resources/overrides on my user. I try to apply this permission via >>Get info>>Sharing & Permissions>> Apply to enclose items...
It was very frustrating to me realize how much time it takes. I have been waiting almost 24 hs. to get this permission to continue the process of the task and till now, have not finished.
I really don't know if I have done something wrong, but I need at least to stop this process (Applying privileges to "Overrides") to continue work with my computer. I uploaded a photo to show precisely what I mean.

If you have any clue to stop this process I would really appreciate.

Thanks in advance!

It is not running, it is hanging. Did you try Force Quit the Finder? I would. I would do it in 30 seconds - not 24 hours. Not sure if it can do it, but would be first thing I'd try. If that fails, hard reboot the computer works always.
You should not be changing privileges, but put the file there with admin authorization. I assume that would work. And system should simply ask for the admin credentials when you drop the file there. You may need to disable SIP first, possibly.
