I have two iMac 27" and running FCPX 10.2.3 on each one. I need to move a bundle from one computer to the other and continue editing on the one that I moved the bundle to. However, I have not been able to do so and cannot figure out a method to accomplish this.
You connect both iMacs with Thunderbolt cables (dedicated TB cables, it also works if one Mac still has Firewire, you'd then need to buy a FW>TB adapter). Then you restart the Mac with the bundle while holding down the "T" key, and it will appear on the second Mac as a volume from which you can copy the bundle. Afterwards, eject the volume and shut down the computer.
