I'm a mac user and have been using LR 6 for about 2 months. Out of nowhere, it started freezing immediately after opening. There are two dialogue boxes that pop up as it opens, but they are so fast, I can't read them. I have tried restarting the computer, done my mac software updates, I've reset preferences, and I've deleted the lrcat.lock file. Nothing has helped. There is more than enough disk space, too.
Could you please let me know the version of Lightroom installed on your computer ?
Also what is the exact version of MAC you are working on ?
Hi! I'm using a 2012 iMac (10.8.5 OS-X). It's LR 6.
Please make sure Lightroom is updated to the latest version , Lightroom 6.4 : Keeping Lightroom Up-to-Date
