Comment 1 Chris Hamons 2015-03-24 14:30:18 UTC
From SecRandom.h

int SecRandomCopyBytes(SecRandomRef rnd, size_t count, uint8_t *bytes)

Now, in theory mono shouldn't be using an 10.7 API if we're supporting 10.6. 

This is a mono issue (System.* isn't XM).
Comment 2 Chris Hamons 2015-03-24 14:38:28 UTC
I was mistaken. This actually is in XM, with a few levels of indirection.

We'll have to look for a replacement for that API on 10.6

Comment 4 Sebastien Pouliot 2015-03-24 15:35:38 UTC
Fixed in mono-extensions/master 1aa80828bdfa8c074069609e7fd588cf30b3fe84
and mono-4.0.0-branch 4123057d899c463df2bffeb58ccd1acad112b241

@Chris I'll bump master and macios-cycle5 but I'm not sure which branch XM 1.12 was tracking, but the fix should be easy to backport
Comment 5 Chris Hamons 2015-03-24 15:37:55 UTC
@Sebastien - I'll get a build going. Thanks!
