Thank god for this thread!!!!! Im using a 2009 27" iMac with High Sierra and steam (and its games) works better than in my main PC
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!

It's been almost a year that I posted this guide and I wanted to do some updates to the guide (since you can't edit posts here after few days passed)
For macOS 10.13/10.14 users, run this terminal command instead:
As a side note, the client may sometimes corrupt itself after it finishes updating. You may also definitely need a newer Steam client (preferably through separate partition if you're not comfortable installing games through terminal) to handle modern game downloads, due to the introduction of ZSTD chunk compression.
And for those who are running macOS 10.15 or 11, despite several months after the announcements, the latest version still works as of making of this post, although Valve will (presumably) update CEF 126 to 138 on the next major release, breaking 10.15 support completely. I will announce that breakage once there are updates made to it.
