Apple has released OS X Server 2.1.1, which has been updated with the capability of managing DHCP from within the Server app as well as adding support for iOS 6 devices to the Profile Manager. The release also enables management of the blacklist settings for the Mail service, prevents spurious “Host name changed” alert messages after restarting, addresses an issue where AirPort base stations couldn’t be managed after updating from previous versions of OS X Server (as well as some other migration issues), and allows for setting a default NetBoot image in the Server app. ($19.99 new, free update, 136 MB, release notes)
Compare More Easily in Apple Mail
In Apple Mail, if you need to work back and forth between two different views of Mail's mailbox contents, you can do so quite easily. For example, you might want to look at a mailbox holding all filtered-in sales orders from the past week while also looking at a smart mailbox showing unanswered customer questions.
To avoid constantly clicking between mailbox views and losing your context each time, choose File > New Viewer window to get a second window and then arrange each window as desired.
