Can't install fdb package on macos - "This package is incompatible with this version of macOS."

I’m running into a weird error trying to install the latest version of foundationdb (FoundationDB-6.3.12) on the latest version of macos (11.3)

The shasum matches what is listed on the downloads website (93833b6...) Does anyone know whats going on here? Or how to debug the install script?

There’s discussion about this on

Ah thankyou - I evidently searched using the wrong part of the error message.
