Can't get OS-X EL Capitan 10.11 to install on my new iMac
I’ve been struggling since yesterday with no luck to install EL Capitan 10.11.6 on a new iMac 21.5.
I changed successfully the date on Terminal (in boot recovery), but after that it gives only the option to reinstall Catalina. I have a carbon copy image of El Capitan from another iMac that did not work, and, the installer, but this last is impossible to execute. and doesn’t appear in Boot recovery.
Any help and assistance will be greatly appreciated. I feel frustrated, cause I contacted Apple before buying to make sure it is possible to install OSX 10.11. and the assured it was no problem..
