This article has been archived and is no longer updated by Apple.

Symptoms

Learn about compatibility with the 64-bit kernel included with Mac OS X v10.6.

Resolution

Third-party software (such as a virtualization engine) or hardware (such as a PCIe card) that relies on a kernel extension which was compatible with Mac OS X Server v10.5 may not work on Macs that use the 64-bit kernel in Mac OS X v10.6. Contact the software or hardware vendor for an updated kernel extension that works with the 64-bit kernel in Mac OS X Server v10.6.

As a workaround, you can temporarily start up with the 32-bit kernel to use older kernel extensions for your third-party software or hardware.
