You need to erase the whole physical drive and reinstall macOS. Here is what the previous owner should have done before selling the laptop:

FYI, in later versions of macOS you may need to click on "View" within Disk Utility and select "Show All Devices" before the physical drive appears in the left pane of Disk Utility. Erasing the whole physical drive is preferred even though Apple's documentation does not show this which is unfortunate and disappointing.


In addition to using Recovery Mode (Command + R) you can try using Internet Recovery Mode (Command + Option + R) to get access to the latest version of the macOS installer (assuming the laptop once had macOS 10.12.4+ previously installed at some point).
