Good idea for a thread!
I'm using LR 3.6 and everything seems to be fine EXCEPT that I can't import from USB camera or iPhone, LR just does not recognise the devices.
Imports from SD card (in sd slot) and the built-in OS X apps can see the cameras but LR does not.
I also have Photoshop Express and it's organise does not see the cameras either.
If anyone has any ideas......?
I have a subscription to lightroom and Photoshop CC. I updated my operating system today to El Capitan and everything in my iMac worked just like it should. I couldn't tell the difference from before to after the update.
Sent from my iPhone
If it's any help to anyone I went ahead and upgraded to El Cap (Super Duper clone first) and LR 5.7 seems to be working fine, although I haven't really tested it extensively, not really had the time.
