For management of large Mac deployments, one of the more venerable tools for administrators is Apple Remote Desktop. The application not only provides information on the status of every Mac on a network, but allows admins to push software loads, remotely control machines, and do detailed asset management.
Yesterday, Apple updated Apple Remote Desktop to version 3.3.2. The new update provides better performance in terms of the remote management tools, as well as better overall stability. There's an update (4.21 MB) to the client software (which is part of the OS and enabled in System Preferences), as well as a much larger update to the administrative software (51.41 MB). The updates require Mac OS X 10.6 or later, Mac OS X 10.5.7 or later, or Mac OS X 10.4.11, or the equivalent Mac OS X Server version. The update requires at least Apple Remote Desktop 3.0 to be installed, although there is some limited compatibility with 2.x client software.
So, what's fixed in 3.3.2? Setup is improved, with additional support for clients using Network Address Translation (NAT) and better reliability when new client computers are being authenticated to the admin software. Previous versions had issues with reporting failed software installations, issues with reporting of MacBook Air MAC addresses, and some problems with reliability of reporting systems configured with AirPort. Those issues have been addressed in 3.3.2.
The fix also provides improvements with the remote assistance features, particularly with systems with dual graphics processors or two displays. Mouse cursor tracking while controlling remote systems has been improved, and there's more reliable drag-and-drop file copy to remote Macs. You can download the update at Apple's Support Downloads page, and it is also being delivered via Software Update.
