Delete Mojave Patch

I bought a used late 2011 macbook pro. The previous owner installed a patched version of mojave. Its extremely glitchy, for example icloud doesnt connect, pop ups dont get blocked etc etc.

I tried restoring with original software but upon doing so im requested to enter the original apple id and password.

I would like to just set this computer up with the most recent compatible software but dont know how.
