Apple has a new parallel linker which may or may not be of interest : https://twitter.com/davidecci/status/1665835119331135488

At the very top of mold's README (my guess is no, it won't become OSS):

> This repository contains a free version of the mold linker. If you are looking for a commercial version that supports macOS please visit the repository of the sold linker.

That has been there for a while so I think it's still an open question of if this change of strategy applies to that repo too

Looks like someone filed an issue about this https://github.com/bluewhalesystems/sold/issues/35

I don’t get why Apple doesn’t sponsor the project and make Mold the default linker in Xcode.

Give him a stack of cash for his work and make all well with the Universe.

It’d be so easy for them.

They're developing their own parallel linker - https://twitter.com/davidecci/status/1665835119331135488
