Use SecRandomCopyBytes on MacOS#322
Conversation

I know very little about Macs but at least Travis seems happy enough. According to the API this has been available since 10.7 which apparently was released in July 2011, so I guess that's good enough (otherwise it could potentially try falling back to /dev/random or urandom — though with an extern fn it would probably just fail at link time). |

Ah, you did find the minimum version. I promise I did a thorough search, but that was half a year ago 😄. With 10.7 as minimum version we are good to go, as that is also the minimum version supported by Rust. |

There was a problem hiding this comment.
This is removed because nacl is dead? Seems reasonable to me, but it is not mentioned in the commit message.

Sure, my only point was that this is not mentioned in the commit message.

Then you have a good point 😄. But the actual commit that removed nacl was two months ago (this is just one line that was forgotten), so not much to do here.

Is this ok to be merged? |

I am cleaning up some old branches, and this is a change from October...
Using the syscall interface if available seems always better than reading from
/dev/random. I can't find any data on which version of OS X was the first to ship the interface, but it seems to be have been around for a long time. It is also the interface used byring.
