Did you download the right versions of steam for El Capitan/Sierra?
The terminal command is:

open -a Steam --args -forcesteamupdate -forcepackagedownload -overridepackageurl https://web.archive.org/web/20230801221717if_/media.steampowered.com/client -exitsteam

You might have to delete the steam folder in ~/Library/Application Support first to the delete the wrong version.

wow! you the man! I just busted out an old MBP 2015 today and jumped through a hoop to get Mojave back on it.

I stumbled into this issue and the downgrade command and Batman Arkham Asylum now works like a charm - thanks!
