Unable to Reinstall the OS in iMAC
I have an old 2012 iMAC. I just wiped the hard drive clean in Command+R ad tried to reinstall the OS,
I got a window to "Install macOS Sierra, click continue," which I did. I then get a drop-down message:
"To download and restore macOS, your computer's eligibility will be
verified with Apple." I click "Continue." The drop-down menu
disappears, and nothing happens; it will not advance to the next step. It is also connected with Wifi Network and I don't have the DVD/CD with the installer.
How can I get it to proceed?
