Can't open files using QuickTime Player after OS X El Capitan update?
I did the OS X El Capitan update on my computer (version 10.11.4) and now I can't play my files using QuickTime player? Any advice?
I have El Capitan too.
When I tether my Canon 5d mk11 to import video clips, they seem import only as proxy files with the arrow on them. I can't find the actual files ?
Also, now when friends send me videos from their I-Phones I cant open them. I have QuickTime Player 10.4.
Any advice please ???
