reinstall el Capitan and mojave
I'm using various machines, but the system software on all of them gives me errors and I cannot reproduce.
I need to find 2 clean and full installers for ELCAPITAN and MOJAVE. For a variety of reasons, I am not interested in the newer Systems as I have many files which I can only use with the older systems and they were not upgraded. Besides after 30 years on Mac I am too old to learn how to use the new systems.
Since the software is no longer available at the AppStore, where can I find the full and clean installers to put on two different brand new small hard disk (I don't like the USB keys).
Apple suggests me how to install these system software in the empty and new small USB3 drives I bought for this purpose. If I found them I will be able to use the terminal to both make the small Hardware, or any other Apple suggested way to have a totally clean installation.
Could anybody be so kind to give me a link where I can find the TWO system software I need?
I think Apple should still allow older users to find what they need to run the machines they paid for even for a price, rather than forcing them to go crazy and attempting to do so in strange and not Apple blessed ways.
Thanks sincerely to anyone who would want to give a hand.
