Using the Xterm Quartz window ssh in and
dc@dc-dell: xhost +
You should see a message indicating xhost is running properly.
localhost:~ dc$ xhost +
access control disabled, clients can connect from any host
Once you see this... may have to wait several minutes ...I didn't do anything but reran the command xhost + after a couple minutes.. the first time failed with xhost: unable to open display "192.168.0.11:0.0"
and should see nvpp running on macbook
