Yesterday, through a blog post Marc Pawliger Director of Engineering at Google announced the end of Chrome’s support for Windows XP as well as Windows Vista, and Mac OS X 10.6, 10.7, and 10.8, since these platforms are no longer actively supported by Microsoft and Apple.
Marc Pawliger pointed out in yesterday’s announcement that, “such older platforms are missing critical security updates and have a greater potential to be infected by viruses and malware.”
Starting April 2016, Chrome will continue to function on these platforms but will no longer receive updates and security fixes. If you are still on one of these unsupported platforms, we encourage you to move to a newer operating system to ensure that you continue to receive the latest Chrome versions and features.
