Hello
My MacBook air (2011) has OS high sierra 10.13.6, Safari 13.1.2.
Recently found out this version of Safari is not supported by some website such as bank website. What would be the latest OS and Safari to access certain websites?
Thank you!
macOS 10.13.6 (High Sierra) is the end of the line for that MacBook Air. You might want to install Firefox 115 ESR. It is no longer getting new features, but it might let you access some Web sites that High Sierra's old version of Safari is having trouble accessing.
Mozilla Support – Firefox users on macOS 10.12, 10.13 and 10.14 moving to Extended Support Release
Mozilla says they will provide "critical security updates" until September 2024. "After this, no security updates will be provided and you are strongly encouraged to move to a supported version of macOS."

None that are compatible with that computer. Use a different web browser or buy a newer model.
