my PC directory for my pictures is C:\pictures\users\jimdad\pictures
my PC directory for my catalog is C:\lr5ciib\LR5_PSE11_Import_from_LT_2013_06_15
my LR6 catalog name is LR5__PSE11_Import_from_LT_2013_06_15-2.lrcat
my LR6 data directory is named LR5_PSE11_Import_from_LT_2013_06_15-2 Previews.lrdata
I would like your help in migrating LR6 pics and catalog from the PC to the Mac
I already am running LR6 on the Mac
I tried to copy .lrcat and .lrdata and the pics to the Mac.
I ended up with 27k worth of missing pics.
Sincerely, Jim C
Your 27K missing photos are because the folder path and name on a MAC is different than it was on the PC. THe instructions for fixing this are here: Adobe Lightroom - Find moved or missing files and folders . In particular, see Figure 4 and associated text.
Also, just to be 100% clear, there is no importing in this process. Importing is 100% the wrong thing to do.
Even though you have already installed Lightroom 6 on your new Mac, the following might provide you with insight on how to move your catalog and images to the new computer.
Thank you JimHess and dj_paige for your help.
