I run Lightroom on both work computer and home laptop. To be able to access all my images at both places, i have always kept my entire Lightroom library on an external drive. So all i had to do is to carry the drive and plug it in when I use lightroom.
This method has always worked for me until the recent upgrade to lightroom CC.
I noticed that, the images that i imported or edited on one of the computers DOESNT show up in the other! The drive was connected all time, and in fact, i can locate the new images on the drive itself, but NO PREVIEWS in lightroom.
Do you have separate catalogs on each computer? Or do you have your catalog on the EHD?
I have the catalog also on EHD
