To add to my colleagues questions

Windows-like viruses that self-replicate and affect macOS don’t exist because of the underlying UNIX Foundation and permission limitations.

The macOS operating system resides in a sealed and read-only volume that can’t be opened by users or third-party applications.

Mac app security enhancements are sufficient to protect computers from malware.

Adware and Malware can affect computers and are often downloaded from “shady” websites or developers who inject them into downloads.
