I apologise if this has been answered else where but I cannot find it. I have downloaded and pressed install on the El Capitan update, but had Yosemite 10.10.5 waiting to be installed at the same time. When restarting it asked me to install all other updates at the same time. So I am assuming it installed 10.10.5 It went through the El Capitan update but after rebooting I'm still on Yosemite 10.10.5 and see no way to install El Capitan as the App Store thinks its already installed. Any help would be greatly appreciated thanks.
