If you look in Tools > Options > Online Updates, there is a section for sending in OS and hardware info, but the user agent on Linux doesnt include the Linux kernel number in the string (example below). LibreOfficeDev 5.1.0.0.beta2 (82b0bf45d0527db84e11689dc8a15eefaa699409; Linux; X86_64; BundledLanguages=en-US) The kernel version can be gotten from SalGenericInstance::getOSVersion() in vcl/generic/app/geninst.cxx.
@Alex, @Steve: How does the OS part of the user agent appear on your end on Mac?

This is around changing the default for whether we send more or less information - there is a check-box for that in that dialog; more work is required to turn that thing on for some 1% case.
@Alex: Was that on a daily 5.1 or master build, as there should a section there, or maybe it wasnt done for mac.
@Jay : that was 5032 TDF production release
