I have been banging my head against the wall about this for a while.
I purchased a second-hand 2008 iMac and it has been working fine for the last 2 years. When I went to update OSX to Sierra, it asked me for the original owner's Apple ID and password. The previous owner clearly did not follow the correct instructions to hand off the computer. I went through the steps to reinstall macOS here:
Feb 01, 2018 Exit Disk Utility and choose to install the OS. Once Snow Leopard is installed, the Mac will restart to the hard drive and automatically launch Software Update. Let it install the 10.6.8 update. Uncheck all others. Feb 01, 2018 Exit Disk Utility and choose to install the OS.

Mac OS is the most stable operating system for any kind of desktop activity. As a Mac OS fan, you may want to use the Mac OS on your Windows PC to get different operating system powers within the one PC. So that you have to find the best and the trusted software application to install MAC OS X.
I did all the possible permutations of these steps, including formatting my hard drive. Every time when I tried to reinstall macOS, I was given the error 'this item is temporarily unavailable'. Browsing the Apple Support forums, it looks like this is because I do not have the original Apple ID. I do not have this information and it will be impossible to get it.
I then tried this workaround and I was not able to access the iCloud page within Safari

This seems like there should be a simple solution.
