One more reason why macOS is inherently so robust is that it is based on a UNIX core. This means, unless you are an Admin, you cannot get access to the core features of the OS. This makes it virtually impossible to inject a system-wide virus into a macOS device.
There are some companies who claim that they have an anti-virus solution for the mac, but if you were to take our suggestion, you don’t really need to spend a dime on this software, as the macOS is completely capable of handling risks and any rare virus attacks on its own.
