NetSync for iTunes Cannot Determine iTunes Version (MacOS)
Apple recently released iTunes 12.4 which has changed some internal data types and caused a problem that breaks the integration of
NetSync for iTunes with iTunes on Mac OS. Further, they have already patched iTunes to 12.4.119 to correct one of the issues with the XML
file. We expect they will produce additional fixes to resolve the issue they created.
In the interim, our engineers have identified a workaround for the problem and have a solution being tested now. Until Apple confirms and/or
documents the changes to iTunes, we will likely not release a new version of NetSync for iTunes as it cannot be confirmed stable until Apple
stops making adjustments.

NetSync© for iTunes® Not Detecting iTunes
(Windows, MacOS) The latest updates to iTunes, which is also included when you update your MacOS to El Capitan, disables the sharing
of the iTunes XML file. This prevents any application from working with iTunes. You will have to manually re-enable it. In
Preferences->Advanced, make sure the "Share iTunes Library XML with other applications" is enabled. You must
Exit/Quit out of the NSFiT2 software, and Exit/Quit iTunes. Note that on a Mac you must
quit iTunes after you make the settings change. You may then relaunch the programs.
