5/22/2015 update:

Leica has released a new statement regarding the compatibility problems with Apple's Aperture and Photos software when opening DNG files from its M Monochrom (Typ 246) camera. In short, the company advises avoiding Apple's Photos application until an update for the software is released 'in the near future'. Leica recommends that customers use Adobe Lightroom or Photoshop until that happens.

Leica Statement:

Following further research and testing, Leica Camera would like to clarify the situation with the Leica Monochrom (Typ 246)’s DNG files and Apple’s imaging App’s in Mac OS X Yosemite 10.10.3 and 10.10.4. The problem is referring to the Photos app and Aperture.

Importing Monochrom (Typ 246) files into a Photos or Aperture library will cause the library to repeatedly quit unexpectedly on launch, and Leica Camera does not recommend using the Apple ‘Photos‘ App for DNG files from the new Monochrom (Typ 246) until this issue is addressed. However, importing these files does not cause any data or image files to be lost in an existing Photos library.

Leica and Apple are collaborating to resolve this issue and develop a solution so that the DNG files from the new Monochrom can be used with the Photos app without any issues in the near future. It is anticipated that Apple will have this resolved in the next update for Photos. Libraries that experience this issue will be recoverable when the issue is resolved. The user can also revert to a backup of their library made before importing the Monochrom (Typ 246) files.

Meanwhile, Leica Camera recommends that all users of the new Leica Monochrom to use Adobe Photoshop Lightroom CC/6 for DNG files of the new Monochrom. The latest version of Adobe Photoshop is fully compatible with Mac and Windows PC. The JPEG files from the new Leica Monochrom work with all Apple applications.

Leica Camera Inc. will include a ‘Warning Notice‘ regarding the Leica Monochrom (Typ 246)’s incompatibility with Apple’s Photos app in all the new Monochrom product boxes (catalog #10930).


Original story:

Users of the new Leica Monochrom (typ 246) risk wiping out their Apple Photos library if they try to use it to store the DNG Raw files created by the camera. This comes from a statement published by Red Dot Forum, a website operated by folks who run the Miami Leica store. Mac computer owners running OS X Yosemite will find the files cause the library to crash, which Leica says could lead to all images saved in the library being destroyed.

Leica says it is working with Apple to resolve the issue, and expects the fix to appear in Apple's next Photos update, but until then Monochrom (typ 246) users should avoid attempting to load Raw files to the application. The company stresses that JPEGs from the Monochrom are fully compatible, as it is only the DNG files that cause a problem.

Original Leica Statement:

Leica Camera would like to inform you that the Leica Monochrom (Typ 246)'s DNG files are currently incompatible with Apple's 'Photos' App in Mac OS X Yosemite causing the library to crash and potentially lose all existing image files in the Apple Photos library.

As we will start shipping the new Leica Monochrom in the coming days, it is important that all dealers, sales personnel and customers are aware of this incompatibility issue.

With the new Apple 'Photos' App, when loading Monochrom DNG files from the new Monochrom, the library will crash continuously on loading. This may cause the Apple Photos library to be destroyed. This means that pictures previously taken with any other camera will be lost. As such, Leica Camera does not recommend using the Apple 'Photos' App for DNG files from the new Monochrom (Typ 246) until further notice.

Leica and Apple are collaborating to resolve this issue and develop a solution so that the DNG files from the new Monochrom can be used with the ‘Photos' App without any issues in the near future. It is anticipated that Apple will have this resolved in the next update for 'Photos'.

Meanwhile, we recommend all users of the new Leica Monochrom to use Adobe Photoshop Lightroom CC/6 for DNG files of the new Monochrom. The latest version of Adobe Photoshop is fully compatible with Mac and Windows PC. The JPEG files from the new Leica Monochrom work with all Apple applications.

Leica Camera Inc. will include a 'Warning Notice' regarding the Leica Monochrom (Typ 246)’s incompatibility with Apple's 'Photo' App in all product boxes.
