Hi, I have coming into a problem of not show a connected Icon in the Device View and cannot start a backup.
As the picture shows, the iPhone is connected to the Mac, and can be find in Finder.app. But BBacukupp show a red not connected icon in the Device View, right after I add the device in the app.

Do I need grant other permission to BBackupp?

The same device and environment, I opened a BBackupp@Version 1.1 (14), it works.

macOS: 14.4.1 (23E224)
iOS: 10.3.4
BBackupp: 2.12 (66)

I have no idea about it. It used the almost same code for detecting devices. Try to debug yourself. :)
