I am trying to reinstall OS X on a 2009 erased iMac. When trying to input the apple ID and password to reinstall, I get the "try again later" message since that apple ID was not the original one to install the software. I have tried downloading software (Sierra since El Capitan was not available in the app store) under that apple ID but it didn't make a difference. I have tried 1000 times to get the Internet Recovery option to work in order to reinstall OS X on my iMac and it does not work. The only thing I can think of is that the wireless keyboard isn't connecting until after I need to press ctrl opt R. I have also attempted to use Disk Maker but it came back with an error. Any help would be GREATLY appreciated. I sold this iMac to a friend and now I'm trying to get it up and running for her. I didn't want to sell it to begin with so this band-aid is coming off slowly... Thanks!
