I need frequently to export photos with edits from my laptop and import those into my main computer`s lightroom (a MAC OS with a lightroom 5). I thought the Export catalog command permitted this but on my last import from such an exported catalog I found no flags or edit history was retained (although star ratings and the final edit state are retained). I thought that was the point of the export catalog function (otherwise, I could simply copy the folders with the .xmp files and import those). Am I missing some setting? Thanks.
It works for me when traveling, although I have a dedicated on-location catalog with the images and catlog all in a single folder on a high speed SD card or external drive. There is no need to export. Everything can be imported from the on-location catalog and combined with the master catalog. Both versions of LR should be the same.
