I had installed Mac OS X on my system. The problem is that i had set an administrators password on my laptop and now i can re-collect that particular password. So, i would like to re-arrange the boot sequence and place a password on the boot sequence configuration settings. Can any body tell me that how can i change boot sequence in Mac OS X? Does any body knows about it? Kindly provide me the correct solution for the above issue. any kind of help on the above issue would be appreciated.
