i normally use my imac for editing. The next weeks i am going on a trip and have some editng work to do, wich i will do on my macair. The question: when i am home, how do i transfer my work to the imac? I want to put the pictures included the editble changes into lightroom.
The easiest thing to do is to put the catalog, previews, and original images on an external hard drive and move the drive from computer to computer as needed.
Alternatively, you can select the images you want to transfer, "export as catalog" including the "negative files", copy all of this to your other computer, then "import from catalog". Repeat when going in the other directly.
