The error message sounds like a lie to me.

I've filed a bug report with erlang for you: ​https://bugs.erlang.org/browse/ERL-1407

[ryandesign (Ryan Carsten Schmidt)]

They already had a "fix" for macOS 11.0 in erlang 23.1 but it didn't work for 11.0.1. They "fixed" it for 11.0.1 in erlang 23.2. But both the 11.0 fix and the 11.0.1 fix were wrong in that they broke the test for macOS 10.x. The've now decided the test isn't needed at all and can be removed: ​https://github.com/erlang/otp/pull/2871

[ryandesign (Ryan Carsten Schmidt)]

Oh, 23.2 is not yet released. So maybe the complete removal of the version checking code will land in 23.2.

Until then, here's a PR to update to 23.1 and add a patch to remove the version checking code:

Thanks for your help.
