i'm using a PowerBook G4, 1.67 ghz, (no intel).
i first tried installing Avid (no Mojo) last week with the dongle in the USB port when i was on OX 10.3.9 and it said error installing. So I called Avid (it was during the week so i was able to talk to them), and she said the problem was i needed to upgrade to OSX Tiger. So I went ahead and purchased/upgraded to Tiger and re-installed Avid. Maybe i should have checked to see if the Avid (though not working) was already installed and to de-install first. But i didn't. (although i doubt that's the problem). And now it says:
It sounds more like an Avid (or other third party)-installed kernel extension may have gotten lost in the new OS install process
(I don't have "DigiDal.kext" file on any non-Avid Mac I use, so I'm guessing it's not part of an OS X install).
When you installed Tiger, if you did an "Archive and Install," which creates a "Previous System" folder, it could be hiding in there, and easily dropped back into the correct folder (administrator password required).
Otherwise a re-install of Avid might have to do do the job.
