I have 4.3.24 version on Mac OS Yosemite and 4.3.24 on Windows 7.
Connecting from Windows 7 to Mac OS and all is well, I can connect iPhone 6 (8.1)
On Windows7, go tosettings -device – connect the USB device and choose the iPhone. After waiting a few seconds, I get the error message.
There may be a problem in iOS 8.1?
