Imac has been fully wiped and has no macOS.
I’ve been given a 2011 iMac from my friend who wiped it and hasn’t left macOS on it so I’m able to start my own account. When I turn it on the screen is white and shortly after I get a icon folder with a question mark blinking. I’ve tried to connect a Magic keyboard and mouse but due to no way of selecting Bluetooth they can’t connect and I’m unable to attempt Command R etc. I’ve tried connecting a usb keyboard but there’s no power going to it. Oddly a usb mouse is detected as mouse light comes on. Is there any way I’m able to get macOS installed on the iMac considering I have no way to use a keyboard at this stage? Please help me I’ve been battling with this for days?
