I just 'updated' to LR 6.2.1 on a Mac 10.10.5. First off the interface is all new, and terrible, but worse the import from a SD card is already into the 2nd hour and not even half way downloaded
thanks for the hint. I tried it but LR is still running crazy slow, and I really hate the new interface. i think I need to delete LR and go back a version.
Apologies for the troubles caused due to the new import window.
You can refer this article to roll back the version : http://www.lightroomqueen.com/how-do-i-roll-back-to-lightroom-2015-1-1-or-lightroom-6-1-1/
