Honestly Linux does work pretty much just as well as MacOS if you run it on hardware thats super well supported and that tons of linux users use. MacOS has integration with its hardware because its all made by the same company. They only have to support a few models of computer.

If you installed Linux Mint today on a Thinkpad t480, and on some obscure weird laptop with rarely used hardware your gonna get 1 install that just works out of the box and your gonna get 1 that you have to hunt for drivers, and do tons of work on. Its just the nature of being able to use any hardware. Some will work better than others.

If you want an example of how to increase adoption you pick a line of computers thats of high quality and have them be supported by the community a ton. Then you convince the company that makes these computers to ship a version of them with linux pre-installed, and potentially help atleast with funding the development of whatever distro they use.

If your average user bought a laptop, opened it, turned it on, and it had linux on it and worked relatively well, they are never going to change it. Its not a normal thing to just change your OS most people don't even know that you can do that. I gave my grandmother a linux mint laptop and she thinks its windows.
