The hardware macOS runs on is far more secure than other laptop/desktop platforms and macOS is the only OS available for it which uses most of the hardware-based security features. The issue is you're completely hard locked on Apple then. Choosing a desktop OS today is a losing battle.

Desktop OSes in general fall behind on adding security design / features that have been researched for decades. Linux distributions are incredibly behind on this and no one should be expected to configure things like SELinux to make it comfortable. Linux is a gigantic monolithic kernel written almost entirely in a memory unsafe language. It's good to have many vulns but having hundreds discovered over days will become unsustainable.

A lot of the mobile OSes started development decades after the desktop, there was far more research on secure OS design by that point and so a better foundation to run on.
