The Quadra 840AV surprisingly does not come with a cable for Apple's new AudioVision Monitor. This in itself would be understandable if the monitor came with a working cable, but the cable doesn't plug into any of the 840's ports. Evidently, Apple plans to add the proper port to future 840s, but in the meantime you have to call Apple and order a special cable. Russ Black <firstname.lastname@example.org> posted a note about this on comp.sys.mac.announce and said that Apple charged him for the cable and that their current computerized ordering system didn't even know about it. Apple, you can do better!
Set Password Activation Time in Snow Leopard
In Snow Leopard, you can now set an amount of time after your Mac goes to sleep or engages the screen saver before it requires a password to log back on. In Leopard, the option was simply to require the password or not. Choose among several increments, between 5 seconds and 4 hours, from System Preferences > Security.
