@srebhan The Makefile change is correct, but it changes the leading path-component count in the darwin tarballs and scripts/mac-signing.sh extracts them with --strip-components=2 and then signs Resources/usr/bin/telegraf. With the new layout the binary extracts to Resources/bin/telegraf, so the codesign step would fail. package-sign-mac only runs in the release/nightly workflow, so PR CI doesn't exercise it. Suggest changing mac-signing.sh:107 to --strip-components=1 in this PR.

Hey @srebhan, quick summary:

• Makefile: .tar.gz now archives the package dir itself ($(notdir $(DESTDIR))) instead of its contents (.). Archiving . is what triggered the tar: .: Cannot utime / Cannot change mode errors on extraction.
• scripts/mac-signing.sh: --strip-components 2 -> 1 to match the new layout (one fewer leading path component).

Tested on my Mac, tarball extracts cleanly. Ready to go.

@srebhan Thanks!
