> Apple allows you to provide an alternative API on OSX

I'll need a source for this claim considering that no driver-level Vulkan implementations are available on macOS.

macOS is not popular among gamers? I don't understand what the problem is.

No. Provide a source that Apple actively prevents it.

Developers can ask users for their admin password, sudo to root and largely do whatever they want including adding kernel extensions and drivers.

kext's must be signed now, Apple can freely revoke developer certs and block them if they so desire.

Signing was designed for security purposes which is the only reason where certificate revocation has been used to date. There seems to be a lot of FUD here but without any actual hard examples.

But it prevents doing what you just said above :

> Developers can ask users for their admin password, sudo to root and largely do whatever they want including adding kernel extensions and drivers.

Having a technical means to make distribution of a driver awkward is quite a few steps short of forbidding it.

But they only use these power to shut out malware. Not to nix software they don't like.

Windows drivers need to be signed as well, whats the problem?

But not by Microsoft, you can opt to obtain WHQL certification for your driver and have MS sign them - but it's also acceptable to get a code signing cert from any trusted CA.

Apple controls all the keys for macOS, AFAIK there's not even an option to add additional CA's for code-signing trust. To get around this you have to completely disable SIP, and it's rather stupid to tell users they must disable a well-meaning (if somewhat poorly implemented) security feature to install a kext because Apple doesn't like you (no knowledge if this has happened, but it can, and I don't care for that).

> sudo to root and largely do whatever they want

Not anymore, even being root doesn't give you total control now[1], and custom kernel extensions are among the things that are prohibited.

This «feature» bas been introduced in El Capitan for «security reason».

It's easy to disable System Integrity Protection:

Let's not forget the post I was replying to :

> Developers can ask users […]

Have you ever seen anybody shipping software asking their user to do stuff like this to get their software working ?

> Boot to Recovery OS by restarting your machine and holding down the Command and R keys at startup.

Sure, and your grandma (=proxy for mainstream user) is surely going to do that.

It's simply a no-go for the mainstream market that expects things to just work.

It's a dead platform with no market-share.

I think the parent claim is that Windows Mobile is a dead plarform, which, it pretty much is, after the nokia fiasco.

Yes. Meant Windows mobile.
