i would like to use this laptop to access my Chase bank account. the site Chase.com won't let me proceed until i update my Safari to version 16.0
MacBook Air (2018 – 2020)
This is Chase's problem to fix. They need to stop using the outdated and privacy-intrusive "user agent" query. Unfortunately, that leaves you out in the cold until they realize the error of their ways and correct it.
The workaround for end users who are unable to update their Macs to a newer macOS version is to use a different browser.
Consider Brave:
Firefox is a distant second choice:

The bottom line is that there is nothing wrong with your Mac's version of Safari, but that bank is using an outdated and ill-conceived method of determining browser requirements. If you are so motivated direct their attention to the WWW publication User-Agent Client Hints (courtesy VikingOSX). Chase is the only large commercial bank still using that method, so what's stopping them can be nothing but incompetence.
