Mac OS 9: Third-Party Scripting Additions May Affect Startup

During startup, the computer stops responding ("freezes"). An "unimplemented trap" error message may also appear.

Solution

1. Start up the computer with extensions disabled. (Hold down the Shift key while turning on the computer until the message "Extensions Off" appears.)

2. Open the Scripting Additions folder, which is in the System Folder.

3. Temporarily remove non-Apple items (place them on the desktop or in a folder outside of the System Folder). Leave these items in the Scripting Additions folder:

• Desktop Printer Manager
• Dialects folder (Mac OS 9.1 only)
• FileSharing Commands
• Keyboard Addition
• Keychain Scripting
• MonitorDepth
• Network Setup Scripting
• Remote Access Commands
• Sound Scripting (Mac OS 9.1 only)
• Speech Listener (Mac OS 9.1 only)
• Standard Additions
• URL Access Scripting

4. Restart the computer.

5. Third-party items that were removed from the Scripting Additions folder should be added back to the folder a few at a time (followed by a restart), to isolate the issue further. Contact the developer of any items which, when in the Scripting Additions folder, cause this issue.
