I recently upgraded to Leopard and now the "Mac audio track" is grayed ouit in the video options dialog. This was working fine before the upgrade from 10.4.10.

How can I get the option back?

I'm using latest versions of all software (Leopard, Snapz, and QT).

The most likely culprit is when you upgraded to Leopard, the kernel extension Snapz uses to record your Mac's audio was removed. Simply download Snapz again and run the installer (you don't have to uninstall first). This will put the kernel extension back and you should be able to record Mac audio again after that.

If it still is grey after that, just restart and it should start working again.

Thanks for chiming in folks. nensha, please let us know if you have any further problems

It's all fixed now. Thanks for the quick reply (even if I was slow to read them).

Reinstalling is something that I should of thought of. I did do an archive install.

Hmmm. Having the same problem, tried the reinstall, restart, and still greyed out.

Nevermind - my computer was just being obstinate and wanted me to do it twice. Now working!
