Q: upgrade from osx 10.9.5 to 10.11.4
Attempting to upgrade from 10.9.5 to El Capitan 10.11.4 the system tells me it needs 10.11 - not mentioning which release, and in addition I am not able to find any location that allows uploading an interim version.
Copyinfg the installation app from my MBook, whihc I upgrades months ago, results in an error message (probaby defective or altered copy of this app....)
What can I do?
iMac, OS X Mavericks (10.9.5)

You need to download the full installer from the App Store. this will download the latest version which is 10.11.4.
Once it is downloaded and before you install it make a copy of Install Mac OS X El Capitan.app which you can find
in your Applications folder, drag and drop this app to another part of the mac or onto a usb stick or similar. This comes in handy in the future
in case you need to reinstall the OS, saves having to do it over the net.
Click the download button when you get to this screen on the App Store.
