Is there no way to purchase an upgrade on line? Apple support says to make an appt. with the genius bar. I was hoping to upgrade I-movie for a project I am working on. The existing i-movie cause imported videos to run out-of-sync with the audio. Supposedly there is a work-around with i-movie 11 but I have an earlier version. Unfortunately I-movie 11 will not work on 10.5.8. So I need to upgrade but I can't find the help I need on the apple web site.
