I don't know what the audio industry is using but the 10.4 was the first version to get limited support for 64bit. I would say that 10.6 is a fully 64bit compatible OS [1]. Even if the kernel is running in 32bit mode you can run applications in 64bit, if the CPU supports that.

Ah, ok, I see.

Is anyone still using 32bit on OS X?

Interesting thanks. That means I should either be using DMD for everything, or not support OS X 10.6.

I think that would be great. Just expand on what these features do and how they helped you, as if the reader is not familiar with D. I think such a blog post would be great for people who are skeptical about D because of the GC.

I took this approach with my image processing blog post and it got quite popular.

Could you post a link to it, please?

It's one of my favourite blog post because it works as a introduction to ae.utils.graphics, covers interesting material, and tells why the building blocks are like they are. it's also sort-of DbI.
Much like Andrei's "std::allocator is to allocation", fascinating stuff.

I would go with not supporting 10.6. It's a really old version now. BTW, would there be a problem of using both DMD and LDC?

Not sure what do you mean.
Past 10.7, you can use any (provided you avoid TLS).
Currently I use LDC for 64-bit, DMD for 32-bit, also because LDC used to have a bug in 32-bit codegen (fixed since then).

Exactly, that's like all the talk about "scaling" or "big data" on the Internet. Problems we wish we had.

You have no idea what you are talking about! It is mentalities like yours that cause headaches for musicians and engineers who work with RT audio.

Do you realize that even 5 ms of jitter can be felt by the listener and musician as being off? 5 ms of latency can be felt and 20ms is unacceptable.

Now lets say you have 10 plugins being used, all with independent GC's doing their thing. You think it doesn't matter because you did some test in some controlled environment and it "worked" given your set of assumptions and hypothesis.

Yet, when your product gets out in the real world, you will cause enough grief that instead of helping the community you will hurt it.

What if someone wants to use your plugin live? You think it is acceptable to have latency and jitter? What about glitches because your GC decides to run at the same time as all the other GC's?

But keep on dictating how great GC's are for real time audio!

I do commend you for doing a plugin in D, but basically your logic is "It's ok to point a gun at people and pull the trigger as long as it's not loaded"(and we all know that it turns out in the long run).

If you spend 10 hrs a day working in a DAW with thousands of VST's you'd have more of an appreciation of RT audio and design.
