iMac unable to install software
I recently wiped my iMac for my sister to use. I wiped the entire hard drive including the OS which was El Capitan at the time. When trying to reinstall the software I receive this error message when trying to log into my Apple ID. I have tried other Apple ID’s and the same message appears. This iMac is second hand and we do not have the original users details to find out their Apple ID. Any help will be appreciated.
iMac, OS X 10.11
