Apple MacBook Pro Retina 15.4” 2013 A1398 NO OPERATING SYSTEM!!!

I purchased this laptop in 2013 and used it faithfully for almost 10 years! It is in excellent. Working condition. I recently purchased a new MacBook and went through the process of erasing this one so I could sell it. Well… apparently I erased the operating system!

I don’t have time to take it to the Apple Store and mess with it. You’re probably smarter than me and can get it up and running again. Everything functions perfectly on this machine, just needs operating system.
