Verify your macOS High Sierra - Technical Specifications
Verify you have all firmware up dates https://support.apple.com/en_US/downloads/imac
Here https://support.apple.com/en_US/downloads/macbookpro
following this jumps in the link above I see:
MacBook Pro EFI Firmware Update 2.9
First I would go back to >AppStore an see if it presents you with a Firmware update.
2012 is quit capable of running the High Sierra

I have this problem too. I have a MacPro. I currently have macOS Sierra 10.12.6 (MacPro Late 2013). 64G of Memory and plenty of disk storage (300G+). My graphics is AMD FirePro D300 2048. Any suggestions?

I thought this would fix my problem in a heartbeat but after I download the update it says "This software is not supported on your system". I don't know what to do after this.
I have the same problem and I get the same message "This software is not supported on your system". I don't know what to do after this."
