Earlier this year, we announced that Google Chrome would continue support for Windows XP through the remainder of 2015. At that time, we strongly encouraged users on older, unsupported platforms such as Windows XP to update to a supported, secure operating system. Such older platforms are missing critical security updates and have a greater potential to be infected by viruses and malware.
Today, we’re announcing 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. Starting April 2016, Chrome will continue to function on these platforms but will no longer receive updates and security fixes.
You can update to the latest version of OS X via the Mac App Store.
