Everything worked fine with an older version of OS X . Now when I try to load pictures from my Leica cameras Monochrome M and S2 they are intercepted by iPhoto which changes them to jpegs. They are originally DNG files and when I look for them on Lightroom 3 I get a message that they are offline. I can work with them if I insert the memory card in the computer card reader. So it looks like Lightroom can fined them there. Has anyone had this problem with any this or any version of Lightroom? if so how did you fix it?
Hi merlisnorman ,
Lightroom 3 is not supported and compatible on MAC OS X 10.11.
Please try optimizing your Lightroom catalog from File>>Optimize catalog.
Refer Re-linking Files and Folders in Lightroom « Julieanne Kost's Blog to locate missing files/folders in Lightroom.
