If you have previously configured a Remote Desktop 2.2 computer as a remote task server for data collection, then Remote Desktop 3 may stop responding ("hang") at the Task Server pane of the Setup Assistant, or it may display the status of "--" for all client computers.
To resolve the issue, you can update the remote task server to Remote Desktop 3 as well, or select a task server that already has Remote Desktop 3 installed, or use the local system as the task server. To use the local system as the task server:
- Quit or, if necessary, Force Quit the Remote Desktop application.
- While holding Option key, open Remote Desktop. This will force the first-run assistant to appear.
- Click through the first two screens to reach the screen where you specify the Task Server.
- Specify a Task Server with Remote Desktop 3 installed, or choose to use the local computer as the task server.
If that does not resolve your issue, do this:
- Quit the Remote Desktop application.
- In the Sharing pane of System Preferences, turn off Apple Remote Desktop in the list of sharing services.
- Move this file to the desktop:
/Library/Preferences/com.apple.RemoteDesktop.plist
- Turn on Apple Remote Desktop in the Sharing pane of System Preferences.
- Open the Remote Desktop application, and specify a Task Server with Remote Desktop 3 installed, or choose to use the local computer as the task server.
