Reinstalling without Keyboard

[Outburst]

Hello,

I have the latest 27" iMac (32gb) - It's got all the extra's like 2gb graphics ect.. (if this information helps)

I'm trying to reinstall Mavericks although I don't have a wired keyboard, just a wireless one. To enter the reinstall screen I must use buttons upon startup although that isn't an option.

How else can I reinstall? And I mean Factory reinstall?

You need a wired keyboard AFAIK and I don't believe there is a work around this.

Your Apple BT keyboard will work for this. You need to wait until just after the startup chime, then hit command-option-r and it will work. You need to do it after the chime and before the spinning gear comes up.

This will take you to the Internet recovery screen. From there use Disk Utility to erase the drive then reinstall the OS. This will get you the version that came from the factory. (sounds like that is what you want?)

I had an issue trying to connect my Apple BT Keyboard on setup assistant for my mac mini. Upon google research, for some reason, there is an issue with the BT keyboard connecting to some 2011 and 2012 minis, this might be similar for some iMacs. I found no workaround, I went and borrowed a wired keyboard from my friend to set it up.
Misunderstood, thought you meant during the setup assistant, not prior to.

If its an Apple BT Keyboard, holding option and R should work. The keyboard automatically connect and give you time to do that upon the chime.
