MacOs Ventura, unistall Dell Display And Peripheral Manager

This is what I used but it may not be for the faint of heart but it works. Looks scary but it’s OK. Dell has been very naughty in the way they did this for Ventura. Can’t answer for previous MacOS versions but this might be good for Big Sur & Monterey.

You must be the user who installed the DDM or have System privileges.

Be careful if you copy and paste from this reply.  Think this system inserts carriage returns into lines too long for it.  Paste into a text editor to check the commands

Open the Terminal app and enter the following line:

  sudo find /System/Volumes/Data/Users -iname Qisda.DDPM* -ls

Enter your password if it asks for it. You will see a bunch of lines that end with: Operation not permitted You can ignore these.

You should see some lines that look like this but have more spaces in them in fact they will probably wrap around depending on how big you Terminal app window is:

There should be 5 lines like either of the above.

Enter the following command.

sudo find ~ -path'*/Qisda.DDPM*' -delete

Enter the first command to verify that the files have been deleted. Two up arrows should recall it.

Reboot and the DDPM app should be gone.

Found another item to delete.  There is an actual app in /Applications/DDPM/ folder along with a few other  items.  First time I've seen an app installed into a folder.  Just delete the folder.
