Now here’s a cool trick: you can take iSight camera captures when an invalid login is detected on a Mac! This is so cool. Posted verbatim from Mac OS X Hints: “With the new MacBook Pro’s including built-in iSight cameras, I thought it would be useful to take an iSight snapshot of anyone trying to break into my laptop. This is done by tailing /var/log/asl.log for invalid login attempts (both at the login screen and screen saver). I have created an authsight program (1.5KB download) that provides a monitoring daemon which calls the camera after an invalid login attempt, and also includes a launchd manifest. An iSight command line tool named iSightCapture is also required. It would not be too difficult to modify this tool to call home and even email photos should a laptop be stolen.” Setting this up is pretty easy and requires a few downloads and a little work, here are the links to follow if you’re interested in this kind of thing: Download AuthSight Download … [Read more...] about Take iSight Snapshots When Invalid Login is Detected
Ever wondered what happens during the Mac OS X boot and startup process? With Mac OS X it’s a bit more complicated than things once were, and long gone are the days of Classic Mac OS (System 9, 8, 7, 6), where watching our Macs boot up with a series of extensions and control panels that we could always identify by their icon alone, and then go dig around in the Extensions folder to easily adjust what is loading and occurring on Mac boot.

Fortunately an excellent explanation is available via segment at KernelThread , which carefully lists the sequence of Mac OS X boot events, from start to finish. It is fairly thorough and worth a read, repeated below for the inquisitive Mac users … [Read more...] about What happens in the Mac OS X boot process?
