The location of VBoxManage has moved in El Capitan to /usr/local/bin, which means you have to call it explicitly with the full path in this workflow's virtualbox_control.sh. You can either edit the script yourself in the workflow folder, at line 58: From: VBoxManage list vms -l | sed -n -e '/^Name/N' -e '/\nGroups/P' -e '/\nGuest OS/p' -e '/^Guest OS/P' -e '/^UUID/P' -e '/^State/P' > To: /usr/local/bin/VBoxManage list vms -l | sed -n -e '/^Name/N' -e '/\nGroups/P' -e '/\nGuest OS/p' -e '/^Guest OS/P' -e '/^UUID/P' -e '/^State/P' > and then update the path in the 'Run Script' part of the workflow to /usr/local/bin/VBoxManage too. Alternatively, I updated the workflow which you can download from here.
