Just ran a mach bootstrap and I'm now getting:

Attachment: complete console output from `mach build`

Change your mozconfig to use --with-ccache=sccache (without a path)

Comment 3

[Jonathan Watt [:jwatt]]

Thank you, that gets my Mac build working again.

I was using the absolute path because at some points in the past I've been using custom sccache builds. It might be nice if this could be made to work again at some point, but it's not blocking me right now.

Using an absolute path works... but it won't update sccache on its own. IOW, your sccache was outdated.
