I have the safari updated to 14.1.2 but the os is macOS catalina 10.15.7. am I protected from the Pegasus?

Pegasus is a spy software. The company that owns Pegasus employs many people who investigate all operating systems to find out how best they can penetrate the systems in order to insert their software.

If your Mac is up to date with the latest update (currently macOS 11.6) you will make it much more difficult for Pegasus to get into your operating system.

To get the best protection, always keep to the latest update.
