32-bit vs. 64-bit OS X

Smoke is a 64-bit application that can run on either the 32-bit Mac OS X kernel or the 64-bit kernel. Smoke 2010 for Mac required the 64-bit kernel.

If you are running Smoke on a Mac where Smoke 2010 was previously installed, you may need to switch the Mac OS X kernel into 32-bit mode for certain third-party drivers and software to work properly. By default, Mac OS X comes with the 32-bit kernel activated, which can run most 64-bit applications, including Smoke.

To switch the kernel between 32-bit mode and 64-bit mode:

1. Run Applications > Autodesk > Smoke Common Utilities > Service Monitor.
2. In the Troubleshoot tab, click 32 bit or 64-bit.
3. Reboot your Mac for the change to take effect.
