Cannot download El Capitan 10.11 on 2009 pro

I was going to give this computer to someone and went to erase everything based off a post I saw here. When I go now to reinstall the OS is get the following error “ An error occurred while preparing the installation. Try running the program again”. I tried some of the solutions here, changing the date, but that one didn’t work. I did turn the wifi back on to do the download. Should I have hard lined? Anyone have anything else on this? I don’t have another mac to make a usb boot.

Not dead but lacking OS installation media, your options become few and tedious. BDAqua suggested a few alternatives. Another one would be to purchase a retail, white, Mac OS X Snow Leopard DVD and boot from it. Apple no longer sells them but you can find them on the used market.

Caveat Emptor of course.

After erasing and installing Snow Leopard you ought to be able to upgrade it to El Capitan in the usual manner.
