How to detect programmatically that Audio CD is inserted in CD Drive on macintosh?

iTunes has a preference that can take care of this ...

Most audio players will do this AFAIK.

I just did that two days ago.

Send me your email by pm and I will send you the piece of code on thursday.

If you need it before, look for a code sample published by Apple. It has most of the code needed. I don't recall the name, but that should be easy to find.

How do you think this answers his question?

You didn't mention what programming you are using, but all mounted drives get an alias put in the /Volumes folder - you could periodically check the folder or use a folder action script.

He'd have to install a folder action script, and have the user enable it for a folder the user can't normally see. What if his application is a GUI-less application that runs when there is no user logged into the GUI? (And as such, the Finder won't be running.)

Anyway, there are ways to be notified when a device is mounted than continual polling. See:

As you say, however, not knowing the programming environment, we can't point anyone in the right direction.

It'd be interesting to know the higher-level goal.
