I've manually copied files from my time machine backup drive and now I cannot delete them from my computer I got a new computer and I didn't want to do a full time machine restore but rather pick and choose what files I was going to copy off of my time machine drive.

So, I went into the directory, found some files I want, and did cp -Rpv dir /Users/username/dir

However, With the -P it kept the same permissions as the files on the time machine. chmod -R 777 dir doesn't work and neither does resetting permissions from within the 'get info' -> 'sharing and permissions' setting.

How can I get the permissions for the directory back to something that will allow me to delete the directory?
I've sorted it out. First, you need to look at the ACLs that got copied along with the files.

ls -le /path/to/dir


Once you've done that you can see that everything had this:

0: group:everyone deny write,delete,append,writeattr,writeextattr,chown


So, what I did was add a new ACL policy to the directory by doing this: 

chmod -R +a "admin allow read,readattr,readextattr,readsecurity" dir 


Followed by:

sudo rm -rf dir
