I just got an iMac which had Yosemite. I could not open Quicktime in Yosemite and I did a search and found this was a common problem with Yosemite.
Quicktime 7 was already there and so I downloaded and installed Quicktime 10.4 thinking in needed to be updated. Now I have both.
Then I installed El Capitan and the same thing happens.
The window says to - Get Quicktime. Download Quicktime to view this video. Quicktime is free for Mac and PC.
It says - Remove Apple.com and Trailers.Apple.com - which I have done and it still does not work.
It works fine in Safari.
Anyone know what I can do?
iMac 2009 OSX El Capitan
4 Gigs RAM
