There is a browser-specific issue with Device ID generation for Mac.
Conditions: Apple Laptop with Mac OS X Yosemite (10.10) installed, having latest Chrome (55.0) and Safari 9.1. These browser report different OS version in UserAgent string.
Chrome: OS X 1010 (correct)_
Safari: OS X 1011 (incorrrect)_
I know nothing about company's politics regarding OS and browser versions and upgrades and if this issue can be reproduced again on other devices.
