Comment (by ryandesign):

 Right, that change introduces the use of `\n` in a sed replacement, which
 older sed in older macOS doesn't understand. You didn't mention your OS
 version, but it must be an older one. `\n` replacement in sed works for me
 on macOS 12 but not on Mac OS X 10.7; I didn't test versions in between.
