How to enable X11 Forwarding with SSH on Mac OS X Lion for Raspberry Pi

Steps in getting an X-terminal from Raspberry Pi Using Mac OS X

1. Enable X11 Forwarding with the “X11Forwarding yes” option set in “/private/etc/sshd_config” for your SSH daemon on Mac in order to receive X11 client request back from  raspberry pi through ‘ssh‘ with the -X option set.
    user@mac~$ vi /private/etc/sshd_config
    uncomment and set to yes "X11Forwarding yes"

2. Allow remote client to use Mac's display
    user@mac~$ xhost +

3. Login into the raspberry pi with -X option to install packages
     user@mac~$ ssh -X pi@192.168.1.10
