Changes between Initial Version and Version 1 of Ticket #21218, comment 12

-              initial
+              v1
 The only binary out of all listed in the postflight script that has setuid bit is {{{VBoxNetAdpCtl}}}. The rest don't have it.
+Can it be that it fails for set the bit due to some MacOS restrictions?
+Why?
+Let's investigate the install package:
+{{{
+amaksoft@amaksoft-mbp ~ $ mkdir VboxPkg
+amaksoft@amaksoft-mbp ~ $ cd VboxPkg
+amaksoft@amaksoft-mbp ~/VboxPkg $ xar -xf /Volumes/VirtualBox/VirtualBox.pkg
+amaksoft@amaksoft-mbp ~/VboxPkg $ cd VirtualBox.pkg
+amaksoft@amaksoft-mbp ~/VboxPkg/VirtualBox.pkg $ cat Scripts | gunzip -dc | cpio -i
+blocks
+amaksoft@amaksoft-mbp ~/VboxPkg/VirtualBox.pkg $ cat postflight | tail -n 15
+#
+# Workaround for 10.11 beta 6 in which the above chown strips the set-uid-to-root bit.
+#
+SET_UID_BINARIES="MacOS/VBoxNetAdpCtl"
+for bin in ${SET_UID_BINARIES}; do
+    chmod u+s "/Applications/VirtualBox.app/Contents/${bin}"
+done
+# Install provisioning profile if present, needed by VBoxHeadless.
+if [ -f /Applications/VirtualBox.app/Contents/embedded.provisionprofile ]; then
+    profiles -i -F /Applications/VirtualBox.app/Contents/embedded.provisionprofile
+fi
+exit 0;
+}}}
+The install package only applies setuid to {{{VBoxNetAdpCtl}}}, which matches the binaries atributes I observe above.
+Why doesn't it match the trunk state?
 Anyway, here's the extended workaround shell command:
