Re: [Avid-L2] Re: What should we do with our dongles! will mac 32bit kernel run mc 6 at 64?

The 32 bit kernel runs 64 bit apps, no problem.

It's kernel extensions (kexts) that are the problem. Your San probably
relies on a kext that is now only written for 64 bit.

The 32 bit kernel can't run 64 bit kernel extensions.
