Starting when I upgraded from 10.2 to 10.3 on my Mac G4, every time I boot or try to open an OS9 app, Classic fails to boot. The error message is: "There is a problem with updating the Classic-specific files. Classic was unable to update its files in System Folder on MacHD."

I don't understand the implications. Can anyone suggest a way to work thru or around this error so I can occasionally use an older app or peripheral that requires OS9?

When OS X was originally installed, it was necessary OS 9 drivers were installed during the format of the drive. Can you remember doing this or if you did and have installed 9.1, or later, can you access the System Folder?

[krazycat]

Yes, I can access the System Folder. OS9 was installed originally with an earlier version of OS10, and Classic was functioning properly when I was running 10.2 prior to the upgrade to 10.3.

You did install Panther as an upgrade and not a clean install? Sometimes upgrading presents unusual bugs. Haver you thought of formatting the drive, installing Panther and Classic again?

[krazycat]

It has occurred to me that may be one way to solve the problem, but it seemed like stab in the dark. If as you suggest there is a strong probability that it was some glitch that occurred during upgrading, then perhaps I'll try to find some time to reformat and reinstall OS 10.3. I don't recall whether the install disk comes with Classic.

If that doesn't work, would it be an option to just install OS9.2 on a separate drive or partition and simply reboot to it when I need it?

In the OS X installer window theres a check box that says install OS 9 drivers. Did you check the box on the upgrade.

Partition or an additional slave drive would be the go and personally favour a small second drive, say of about 40GB. Set it to slave, mount it over your current drive on the caddy and just connect to the additional IDE connector.
