1. An Intel Haswell CPU equipped Mac for perfect sync
2. A TV capable of identifying and displaying 24p video
3. Adjust display refresh rate to match video - ON
24p video to a 60Hz display has to undergo a technique called a 3:2 pulldown that adds extra frames and causes minor juddering in the picture when the camera pans left to right. Most people likely do not even notice. Some are sensitive.
Yes, and I am such a person. I don't expect perfect 23.976Hz -- I am aware of the Intel 24p bug.
What I want is 24Hz display with audio sync'ed to that. The two options, in conjunction, by their descriptions, should get what I want.
But what you were suggesting -- that the two options are mutually exclusive -- implies that Kodi is unable to keep audio in sync with anything but 60Hz. By that, I mean that if I uncheck the "Adjust Refresh Rate" option and enter Kodi with the display already set to 24Hz, it should be no different than having Kodi adjust it.

If it is able to sync audio to 25Hz, then why not 24Hz?

Video is 23.976fps, and this results in the 3:2 pulldown as explained above. Video is not Jerky. You cannot set an iMac running Kodi to 24Hz and get acceptable video results.

That's just it. With the test build in this thread, the results
are acceptable (i.e., it works for me), but I'm being told that this is an invalid configuration, and I'm pressing the issue so I understand why.
