That depends on your hardware. It was very fiddly to get it going because the WiFi module in the Spectre wasn't supported at first. But then someone released a driver for it. I also had to read a lot into the documentation and discussions to get my config together. But once that was done, it ran almost like a normal Macbook Pro and I barely had to touch the OpenCore config.
(OpenCore is a bootloader that changes things in memory so your laptop appears like an Apple device to macOS. You then use the normal macOS, can download macOS updates, etc.)
