The core problem seemed to be that on macos, sed doesn't recognize the \w escape character (meaning a letter in a word). So, I replaced \w with [a-zA-Z0-9_] (there are probably characters covered by \w not covered by my replacement, but this captures all the test names we are currently using).
I also made changes to the sed command to make it a bit more readable (at least to me). This meant replacing \ with | as the delimeter of the sed command, and pasing the -r flag to use extended regular expressions (saving us from having to escape parentheses when using them to capture a group, for example).
I did read that -r works for gnu sed while -E is the command to use for macos sed, but both worked on both the ubuntu and the macos machines I tested on.
