On my older Mac, it cannot install!
Same for me. Mid 2007 2.8Ghz 24" iMac. Says graphics card does not meet the minimum requirements. What the heck? The system runs everything from Aperture to Final Cut with zero issues. It can not longer run the new iMovie?
The new iMovie has created a duplicate of all my events into a new Library. Is it safe to delete the old events on the hard disk if I'm not going to use the older version anymore?
