[Bf-committers] OS X has been renamed to macOS

[Aaron Carlisle]

Hi,

In case anyone missed it apple decided to yet again changed their name for
their OS.
In the past, it has been called Mac OS (now used to reference old pre-2001
versions)
and also OS X which has recently been changed to macOS.

What this means is that we should try to convert to using that name.
This means changing the manual, blender.org and folders/files.
The folders/files can wait and happen more slowly, however,
today I will start renaming the other stuff.

Thanks,

Aaron Carlisle
