Using the sudo command will grant access to any folder or file on the Mac.

The commands sudo cd ~ return and sudo cd Desktop return only appeared to fail. In fact, both commands succeeded but exited without any output.

To demonstrate this try the command sudo -i "cd ~;pwd"return which should print /var/root in the terminal window.

In order to use the same commands interactively, do following:

1. sudo -i return
2. cd ~ return
3. pwd return

Output

/var/root

There is. Type:

cd sample_dir

It checks for you. If for some strange reason that doesn't work, type:

cd ./sample_dir
