I was referring to Big Sur through to Ventura.

Have you looked at the thread about Ventura on unsupported Macs?

I am using a MacBook 11,1 and I have never had to delete the plist file to deal with lagginess on a supported OS.

So let me understand. Your MBP is from 2011 and you want to install Ventura on it and you are having trouble? A quick check on apple and it appears a 2011 MBP is not supported on Ventura. So are you surprised it does not run?

Try booting into Safe Mode and deleting the file from Terminal. Also, you can try Target Disk Mode from another machine.

If your machine is running slow, check your laundry demons and launch agents for nonsense.
will try today thanks I will let you now on lunch all apps are out

Nope I still search for resolution but no chance from BigSur to delete files from system library
Have they resolved it to date???

I had also solved it with previous versions and Ventura apparently leaves the main file disk as read-only and I have not been able to delete that file either, which is the one that solves Problem.

I just need to try everything from safe or recovery mode but I suppose it will be the same because the disk is read-only in the system files. Rather, we would have to find a way to remove s Read only entire disk in system file section
