Safari out of date

[George_in_Lawrence]

I have an iMac purchased in Mid 2011 currently running macOS Sierra 10.12.6.

I have encountered a message from some web sites that my version of Safari is out of date and would not open a page I was looking for. For expediency, I downloaded Chrome and use that on the sites that are giving me grief. I am noticing that more sites are giving that message. It appears that I have the latest Safari on the Sierra operating system and need to download a new operating system. What is the latest that is compatible with my hardware? I have a lot of passwords saved in Keychain Access. Will these be retained and automatically be available to the new version of Safari?

Your mid 2011 iMac (21.5- or 27-inch) can run macOS High Sierra 10.13.6 (17G65) maximum. Software Update in System Preferences should automatically offer this update.

If it somehow does not show up, you can get older system versions from here:

OK. I loaded macOS High Sierra 10.13.6 with no problems. However, I am still getting notices that the Safari browser is out of date. Is it possible to move up to a later OS? The web site that lists compatible hardware seem not to go back to my 2011 model.
