I was talking about HFS (Mac OS Standard), not HFS+ (Mac OS Extended).
With the introduction of Mac OS X 10.6, Apple dropped support for formatting or writing HFS disks and images, which remain supported as read-only volumes. Starting with macOS 10.15, HFS disks can no longer be read…
Okay.
Though if both Epic Games and Steam are still using HFS DMGs and not HFS+, that would be lighting up the forums, given macOS 10.15 has been out for a little while.
That would also likely mean other latent issues await within an installer already incompatible with macOS 10.15 and newer, too.
Getting anything built on OS X 10.5.8 or earlier to run on Monterey would be somewhere between unusual and laudable; that was quite close to the start of the 64-bit API transition.
Still seems more likely some local problem exists here.
