Using LRC in a NAS environment with multiple PC/Mac and multiple users
I just posted this to an old (2017) question. If you have a NAS (network) environment with multiple users and multiple workstations there is a way to use LRC so image editing can be performed in a colaborative process. Our Sun City AZ Photography Club uses LRC in this type of environment with no issues.
This will work with a few assumptions about your workflow. First, each PC/MAC has its own LRC catalog and all images and all XMP data is stored on the network.
When you start Lightroom, from Grid View with the subject images selected, perform a Metadata/Read metadata from Files. This fully updates that computer's lightroom catalog from whatever computer's catalog you last used.
At the very end of the session, you repeat by going into the Library's Grid view with the edited images selected and doing a Metadata/Save metadata to files. It takes less than 5 seconds to do each. Of course, only one person can be editing the images at a time, but we have experimented with two people having the image up at the same time. After one person makes a series of edits, they need to do a metadata/save and the other person then does a metadata/read. That will give both people the same state of changes.
