People often wonder what sysadmins do for a living. It’s a mostly-invisible profession, where you’re only noticed when things aren’t working. Mostly we solve problems, but often we first have to figure out what the problem really is.

I don’t want to know how long it took someone to get from “my password doesn’t work” to this:

If you used Open Firmware Password utility to create a password that contains the capital letter "U", your password will not be recognized during the startup process (when you try to access Startup Manager, for example).

Note that it applies to Mac models going back several years, but wasn’t posted on the support site until this week. No doubt there’s a small pile of bug reports that have been sitting around for all this time, with their status field set to “WTF?”.
