A bug in the DNG files created by the B&W camera the Leica Monochrom Typ 246 can cause the new Photos app from Apple to crash and corrupt the existing Photos library, potentially putting every phone in that library at risk. Any attempt to load the DNG-formatted RAW files from the camera will cause the Photo library to "crash continuously on loading," said the company in a service advisory. Until the fix for the issue is released, Leica is suggesting users use Adobe Lightroom instead.
