This page provides information for troubleshooting situations that cause the Classic environment not to start up, to quit unexpectedly, or to stop responding ("freeze").

Match one of the four numbered symptoms with your computer's behavior to find help with your Classic troubleshooting issue.

1. Classic will not start up

If Classic fails to start up, an alert box with one of these messages may appear:

"To start Classic, you need Mac OS 9.1 or later installed. See your documentation for instructions on installing this software."

"No startup volume. There is no volume with a system folder that supports starting Classic. Please install Mac OS 9.1 or later."

"You are running Classic without superuser (root privileges). Ensure that TruBluEnvironment is setuid and owned by root, or reinstall your Mac OS X System Software."

See technical document 106678: "Mac OS X: Classic Will Not Start Up - Mac OS 9 Not Installed or Not Blessed" http://docs.info.apple.com/article.html?artnum=106678

2. Classic begins to start up, but it does not finish

Classic almost completes a normal startup, but then it stalls without any other hint of an issue. See technical document 106835: "Mac OS X: Classic Startup Stalls When Almost Complete" http://docs.info.apple.com/article.html?artnum=106835

The Classic startup window shows evidence of an extensions conflict or "bus error." See technical document 106679: "Mac OS X: Classic Will Not Finish Starting Up - Extensions Conflict or 'Bus Error'" http://docs.info.apple.com/article.html?artnum=106679

If you have a Linksys hub/router or wireless access point, you should also see technical document 106663: "Mac OS X 10.1: Classic May Not Start If Linksys Hub/Router or Wireless Access Point Is Present" http://docs.info.apple.com/article.html?artnum=106663

3. Gray Screen - Classic startup stops ( or "freezes") at a gray screen

Classic startup stops at a gray screen, and there is no indication of an extensions conflict or "bus error" in the Classic startup window. See technical document 106572: "Mac OS X 10.1: Gray Screen When Attempting to Start Classic Environment" http://docs.info.apple.com/article.html?artnum=106572

4. Classic quits unexpectedly or stops responding (or "freezes")

Classic may quit unexpectedly, and the Dock no longer indicates that individual Classic applications are running. Alternatively, Classic may continue to run but become unresponsive to input. An alert box may appear with this message:

"The Classic Environment is Not Responding. You may click Cancel and attempt to save any changes to open documents..."
See technical document 106680: "Mac OS X: Classic Quits Unexpectedly or Stops Responding ("Hangs")" http://docs.info.apple.com/article.html?artnum=106680

5. During copy/paste, Classic stops responding ("freezes") with a spinning disc cursor

See technical document 106669, "Mac OS X: Spinning Disc Cursor When Copying/Pasting From Classic". http://docs.info.apple.com/article.html?artnum=106669
