Hi
There are so many things to this.
A. Flash drive - I even don't know if they would ever work - very doubtful
B. External hard disks - MUST be Mac OS Extended (hfs) formatted -
UNIX/DOS/FAT32/Mac OS Exchange works for most other things BUT NOT FOR VIDEO no matter if iMovie, iDVD or FinalCut is used.
C. In the folder iMovie Projects - There are NO MOVIES - but text-documents related to the projects and this document points to the Raw material in iMovie Events folder and how it is supposed to be Played/Viewed in this particular project. e.g. play Clip A from 00:00:01:13 to 00:03:45:02 and so on. So there are no movies in the project folder.
D. So if both iMovie Events and iMovie Projects folder are copied over to an external hard disk - Then the iMovie in the second Mac has no links to this and will not find it.
SO to be able to work with one project on two Macs - all moving's of Events and Projects should be done within the iMovie Application - Not on DeskTop/Finder - do not alter or move any folder named
• iMovie Events
• iMovie Projects
on DeskTop/Finder - as they can mess-up and be very hard to impossible to mend.
Yours Bengt W
