Hey I'm trying to download this mod on mac and when I enter the first code I receive this error.

End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of unar.zip or
unar.zip.zip, and cannot find unar.zip.ZIP, period.

Anyone know why my terminal is doing this? Any help would be appreciated.
