Why is my Mac not installing macOS Sierra?

I recently attempted to install macOS Sierra on my Mac , but for some reason, the installation process keeps failing. Each time I try to complete the installation, I receive an error message. I've tried restarting my Mac and running the installation process again, but I keep getting the same error message while the price is very high but not work . I'm not sure why the installation is not working, and I'm looking for a way to resolve this issue.

Sierra can only install on Macs older than September 25, 2017 and newer than where (x,y) is the machine ID in the System Report.

MacBook (Late 2009 or newer) 6,1 up
MacBook Pro (Mid 2010 or newer) 6,1
MacBook Air (Late 2010 or newer) 3,1
Mac mini (Mid 2010 or newer) 4,1
iMac (Late 2009 or newer) 10,1
Mac Pro (Mid 2010 or newer) 5,1

If your Apple ID account has been switched to MFA (Multi-factor authentication), you will need to insert the code from your other Mac, iPad, or iPhone running a newer system immediately after the password on any system running 10.12.3 or earlier. 10.12.4 and later support MFA.

Some Macs may not be able to install older operating system without the system clock set back in time:

There is very little reason to install Sierra unless your applications absolutely won't run in High Sierra as the minimum system requirements for both are the same:
