I have MacOS High Sierra 10.13.6 It says no updates available Should I update my OS?

You need a 2012 or later Mac to upgrade beyond High Sierra.
Do I need to worry about not being able to install the new security update?
From my understanding on MacOS you just ned a more up to date Browser than Safari...
Might try this, it's Chrome Browser without google & without Ads...
The security update is for Monterey so I wouldn't worry.
