My current Mac can't run FCP X, but I urgently need it for work. I'm holding out on upgrading my hardware until Haswell this summer, and so would like to begin using it on my housemate's entirely capable iMac, with all projects and events living on an external hard drive. But when I get my new Mac, I'd like to begin editing the projects and events with the new machine but still keep them on the external HD. I'll be getting a 13" MBA, which means space is tight... hence the external HD. So is migrating the drive to a new computer like this even possible? The video-editing part of my job is not massive and our budget is tight, so I'm not interested in an NAS or FCPX Server solution. I just need a plug-and-play solution. TL;DR: Can I keep FCPX events/projects on an external hard drive that I will use on multiple computers?
