Hi,
For security purpose, we have implemented Apache authentication on our AEM 6.3 author servers.
This is causing access issue when using the latest version of Adobe Experience Manager Desktop app, version 1.7.0(1.7.0.3) on machines with Windows and Mac OS.
Prior implementing the Apache authentication, the Desktop app worked perfectly fine.
Following are the screenshots of the access errors with Desktop app after implementing Apache authentication on our AEM 6.3 author server
For Windows,

For Mac OS,
We can now login to the AEM desktop, but the assets don’t show up in Finder/Explorer. In the past the AEM Desktop would put a link on Finder and when you’d click on it, all of the assets would appear. This is the way we place images in our design software (Adobe InDesign). Currently when you click on the link the folder is empty.
