This conversation has been merged. Please reference the main conversation: Lightroom: CC 2015.2 User interface extremely sluggish and unusable
However when I went into the develop module the hard drive and processor started up big time and ALL functions in the develop module became 100 times slower making usage impossible. I followed advice to reset preferences, switch off the graphics processor and the show add photos in the general tab but these made no difference at all. LR was unusable. I then reverted back to LR 6.1.1 and will await an update to 6.2.
However the Creative cloud app no longer shows that I can update.
What I wanted to know was will I be able to update from CC when a new version is made, and will the slowdown occur again when I update. What was the slowdown due to?
I have a 2011 MBPro with 16Gb ram, 2.7 core i7 and running Yosemite.
Thank you in anticipation
