iMac (2017) showing question mark in folder - won't recognise keyboard
I've bought an iMac and it used to be a school computer. It was wiped before I bought it, and did not come with a keyboard.
On start up it is showing the folder with a question mark in it. I'm trying to follow the instructions on the website below, but it doesn't recognise the two keyboards I have at home.
If your Mac starts up to a question mark - Apple Support
I have tried a Mac bluetooth keyboard, and a logitech plug-in keyboard but neither of them are working. Any other suggestions please!
