Hello @wou-aker As I didn't have rights to commit directly into the WSUS Offline Update repo, I would like to suggest that the following commit be made at the Linux scripts, as the ``-I`` parameter isn't available from the native ``date`` command from macOS, so this commit attempts to use the GNU version available from ``coreutils`` package. https://gitlab.com/eduardomozart182/wsusoffline/-/commit/f217c77bd86861539afd4dcfec5d8d9569c1bbfc
