I am running Lightroom version CC2015.8/Lightroom 6.8 It is my understanding that this version on a iMac will allow you to back-up a catalog larger than 4G's but I am getting a message that the LR Catalog can not be backed up because it is larger than 4G's. How do I resolve this to get Lightroom to back-up the catalog?
The warning message is a 'bug' in the recent x.8 version of Lr.
