How to reinstall macOS HighSierra on my old Mac?
Recently, I bought a brandnew MBP to replace my MBP from 2011. Now I want to sell my old MBP and install the newest macOS on it.
I reformatted my old MBP in MacOS Extended (Journaled) using Disk Utility from macOS Recovery. Then I restarted again in recovery mode by holding down option-command-R according to https://support.apple.com/en-gb/HT204904
Unfortunately, I can now only install Mac OS X Lion by logging into the AppStore using my AppleID, but no other/newer macOS. Why is that and how can I install the latest macOS (HighSierra 10.13.3) on my old Mac? I want to sell it with the newest macOS on it.
MacBook Pro TouchBar and Touch ID, macOS High Sierra (10.13.3), 3.1GHz Quad Core i7, 16GB, 1TB
