Generally, yes, unless the author screwed up. You have to go out of your
way to screw it up.

You DO need to sign the 64-bit driver with a code-signing certificate
before it will load, however.

There's a huge amount of information available. Mac OS is Unix-based, and
the Unix driver model is well-understood. Have you checked Apple's web
site?

There aren't a lot of USB video capture driver samples, because most USB
video devices are built to be Video Class compliant, so you don't NEED a
driver. There is a generic USB Video Class driver for Linux; it's possible
that can provide you a starting place.

Not so.

Each UNIX kernel has its own driver model, which is by far unlike the other ones - FreeBSD, Linux, Solaris, Darwin...

Darwin's IO manager is C++-based to begin with.

But yes, Apple's website is the primary source of information for Mac driver developers.
