I just updated mac os x Yosemite to 10.10.5, also iTunes is updated to 12.2.2. I am now getting an error message saying that I need quicktime to play this movie, but this version of iTunes is not compatible with Quicktime. Didn't start getting this error message until I updated Mac os X Yosemite. How do I fix this?
MacBook Air, OS X Yosemite (10.10.5)
