A colleague just advised that since upgrading Mac OS X to Yosemite he can longer open/access any of his digitally recorded movies that were filed in iMovie. All attempts at getting other applications to do the job failed.
Yosemite apparently does not include iMovie among its applications (unless one heads to the Apple Store and pays for it).
Any thoughts on the matter? Such as tacking on some extension which could get an included app (eg, iTunes) to open the movies. Other possible workarounds?
