I have a MacBook Pro (Retina, 15-inch, Late 2013) with OS X Yosemite 10.10.5.
I want to upgrade to El Capitan (10.11) - but NOT Sierra, because I have a lot of music software that is not compatible yet.
But it's impossible to find El Capitan in the App Store, so I called Apple Support, who told me to upgrade using this version:
But that doesn't work, because the App Store says this:
'This version of OS X 10.11 cannot be installed on this computer.'
Does anyone know how I can upgrade to El Capitan without having to download any illegal torrents and meddling with USB sticks etc.?
Thanks!
