The mac build is currently failing on:

shasum: /Users/distiller/.lein/self-installs/leiningen-2.9.2-standalone.jar.pending.shasum: no properly formatted SHA1 checksum lines found
Failed to properly download 
The checksum was mismatched. and we could not verify the downloaded
file. We expected a sha256 of
09805bd809656794cfe7d9155fd4b8bea2646092318690bf68e3c379574a2d3c and actually had
0b320b5ba103b199872e2ec6632dfbc1f3e045455ae35a1f3b5b3b5a2ba3ca16.

i don't know, but as a data point, i downloaded the zip and got the 098... checksum

does that perhaps mean the download got something corrupted or changed?

It seems multiple Mac containers are suffering from this problem, see #circleci
