Thanks for your reply
I did reboot the system.
still can't see new user.
One thing though when the system finished transferring the files
at the end a message came up
" 2013-09-11 04:18:05 +0000 Paul Nirwan could not be created.
I did the transfer two times, same thing. first time I used the WiFi
and second time from my back up disk with USB connection, using Migration Assistant.
Second time also said that Paul'Mac already exist, Paul'Mac 2 created.
How can I get rid of first data trasnferred?
It will be using too much space on hard drive if Ileave it therre.
Since it's a new Mac, the surest thing to do would be to wipe the HDD and re-install the OS clean. You can do this by booting cmd-r and choosing Disk Utility > Erase. Then choose "Re-install OS X". This will be an internet install so it will take some time. Then it will boot into boot into the new system in Setup Assistant and after a couple of screens you'll be prompted to migrate. Follow the on-screen directions.
