How to Downgrade iTunes 12.6 to 12.5 on Mac

Recently, Apple released the iTunes 12.6 and introduced the new function "Rent once, watch anywhere" to its users. According to the release notes, this new feature enables Apple users to play iTunes movie rentals across all devices with iOS 10.3 or TVOS 10.2. That is the good news, but the bad one is that the update of iTunes causes many problems to some DRM removal programs before they are updated to be compatible with iTunes 12.6.

My M4V converter can't start the conversion but it worked great for me. I think the iTunes 12.6 maybe potentially caused this conversion issue. Although I may did a correct diagnosing but how can I remedy this? Downgrade the iTunes perhaps can make my converter return back to normal. Any assistance would be appreciated.

Since iTunes was updated to 12.6, many users have encountered the same issue and sent email to for seeking a help. Actually, TunesKit has released the updated Windows version of M4V Converter, Apple music Converter, AudioBook Converter to apply to iTunes 12.6. The updated Mac version will be released soon.
