Mac OS X 10.5: Unable to start up after installing Apogee audio drivers

Issue or symptom

Installing earlier Apogee audio drivers may prevent Mac OS X 10.5 Leopard from starting up.

Note: Mac OS X 10.4.x installations with older Apogee drivers that are updated to Leopard are not affected by this issue.

Solution

This can happen if you install an earlier Apogee driver on Leopard. Current drivers for the Ensemble and Symphony card can be found on the Apogee Leopard page.

If your Mac is affected, repair permissions and reinstall Leopard:

  1. Restart your Mac while holding the Option key.
  2. When a screen showing the available startup partitions appears, press the Eject key.
  3. Insert the Mac OS X 10.5 install DVD and select it as the startup disk.
  4. After the Mac has started up from the disc, choose a language
  5. Choose Utilities from the Disk Utility menu.
  6. Use Disk Utility to select the system drive and click the Repair Permissions button.
  7. Quit Disk Utility.
  8. In the Select Destination window, choose the partition Leopard is to be installed on. This should be the same partition as used before.
    9. Click the Options button and choose "Update Mac OS X".
  9. The computer will restart after installation has completed.
After your system has been reinstalled, download and install updated Apogee software and drivers from the Apogee Leopard page.
