Migration Complete: PC to MAC Air A2941

I completed the migration without issue and received the "A restart is required to finalize your migrated settings. Your migrated data is ready to use following the restart" message. I clicked restart now and let it sit going on 2 hours now only because I've been busy but I'm certain at this point I need to power down. Is this a common issue in migration of data? This is my first MAC and I want to love it but hate this pause happening right off the bat. Systems background here so I do understand all things can and will happen as they do but also holding on to the high hope that MAC systems will impress me after this hiccup...

Thank you!
