i assume by "unsafe" you mean "unreliable", meaning that if there is
not enought entropy it will block? thats the nature of /dev/random , if
you want non-blocking entropy /dev/urandom is what you need.
i have to say though that i'm not familiar with the details of that on
MacOS (assuming its basically BSD)
