I usually find most of the articles on "ars technica" pretty informative and well researched. However, this latest bit of "reporting":
An errant Command-Q could leave your Mac unbootable:

Command-Q to Quit. Many of us know that shortcut so well that it's used without conscious thought. The shortcut is even honored with its own t-shirt. But an unfortunate MacOSXHints reader ran into some trouble when he hit Command-Q while installing the latest Safari update.
The update was being installed remotely using Screen Sharing. Software Update was showing the progress before rebooting, so Chris Platts hit Command-Q to quit Screen Sharing. However, the keystroke was sent to the remote machine, causing the update to quit. Since Safari 3.1 included a major WebKit update, applications that relied on WebKit started crashing after the aborted update. Oops.
A manual install of the update package cleared things up. But if an OS X update had been in progress, it could have rendered the machine unbootable. Until Apple puts some kind of protection in place, you'll want to keep your hands off the keyboard while updates are in progress."
Leaves me to wonder if they let anyone willing to write report on their site. I almost get the impression that this author "Chris foresman" has only just started using a Macintosh.
I have been using a Mac since May of 2006. My memory of security updates and OS updates are that they are done in such a way that it's impossible to quit Software Update in the process of the update. Maybe not the download, but the actual update itself. In Leopard, I have seen Software Update download the update, then reboot the computer to do the actual install after the system boots back up but before the OS actually starts up.
If Mr./Mrs. Foresman had actually been using a Mac for longer than a week, I think he/she would actually know this fact and not be reporting that it's possible that an errant Command-Q could destroy your OS
I'm actually surprised that Software Update allowed him to quit his update for Safari 3.1. I thought that when I updated that, my system rebooted and finished the update the same way an OS update does. However, I can't say for sure because I wasn't paying that close attention to the update. Plus, I don't go around pressing Command-Q when I'm doing something as important as a software update anyway.
I do run updates via Screen Sharing to my MacBook which is upstairs. I usually let the updating computer kill the connection to screen sharing or I'll close the window with the mouse. I just don't quit Screen Sharing by trying to use Command-Q. Maybe this is because I use "Chicken of the VNC" and Command-Q doesn't work to quit that program unless you have all connections to other computers closed.
Anyway, I hope that ars technica reads the comments about this questionable post and maybe reviews future articles from Mr./Mrs Foresman before he/she is posted on their site. Articles like this make sites like ars technica look a little amateurish. Much like my blog.
