how to reinstall catalina on a MacBook Pro (Retina, 15-inch, Mid 2015)
I wish it were that easy. I have a Macbook pro (15 inch retina display mid 2012) I planned on giving it to my sister in-law.
First I clean (erased) the Hard Drive (actually internal ssd). Then tried to do the "reinstall". Since the HD was completely
wiped, I had to do an Internet reinstall. I was stopped in my tracks with the message "Can't download the additional
components needed to install Mac OS X". Some people had trouble with Internet connections in this Forum - I had
absolutely no trouble with Internet connection. Nobody seems to address the above error message problem.
BTW, I was trying to install "mac OS X Lion", I did not have any other option choice. I later downloaded Catalina .dmg file
(4.5GB), but do not know what to do with it. Thanks in advance, Doug

If the DMG file is an InstallOS.dmg, you double click it which will open a window with an InstallOS.pkg file. You double click that file which will create the Installer app file in your /Applications folder so you can install that OS.
You can go to App Store > search for macOS Catalina > download and install.
