QuickTime MPEG 2 Playback Component won't install on El Capitan?
In order to use MPEG Streamclip this morning on my Mac mini (El Capitan), I copied the QT MPEG2 Component from my iMac (Yosemite) but I was unable to insert it into the HD/System/Library/QuickTime folder.
I simply got a circular "prohibition" sign and there was no dialogue asking me to authenticate as the administrator.
Any ideas?
OS X El Capitan (10.11.2), Mac mini i5 2.5GHz & iMac FCP X
