The new Apple Remote Desktop is an extremely useful and powerful tool for administering Macs (one which I have been meaning to write a review of for a couple of months here…). However, the newest version of the ARD client (3.0, for those playing the home version of our game) is prone to a very annoying tic: it will randomly cease to push screen updates to the administrator client. This means that one must either manually resize the window or wander over to the desktop and restart the ARD daemon… or so I thought.
I finally got fed up with using Sneakernet to admin the boxes with stalled ARD clients, so I set out on a Hunt the ARD Wumpus adventure on Google. Foruntately, I stumbled across this extremely useful tip for restarting the ARD daemon remotely via ssh:
Simply log into the box in question as an admin and type
sudo /System/Library/CoreServices/RemoteManagement/\
ARDAgent.app/Contents/Resources/kickstart -restart -agent
Bingo. Client restarted, fullscreen refreshes recommenced. Excellent.
A Very, VERY Useful Hint For Apple Remote Desktop Users
