Try this:
C-h k M-Tab
and tell us what you find. It should look something like:
M-tab runs the command idlwave-complete
which is an interactive compiled Lisp function in `idlwave'.
(idlwave-complete &optional ARG MODULE CLASS)
Instead, it will probably say a different key/function, probably one with
the word "tags" in it ;)
The issue is likely related to the fact the ESC is another viable
equivalent for Meta,and etags uses a large ESC map. Try ESC Tab (escape
*followed by* Tab) in the same way and report that too.
Good luck with OSX+IDLWAVE -- you're one of the first few I've heard
trying it.

P.S. I find it highly entertaining that new users are beginning to see
IDLWAVE as an integral part of the IDL environment ;).
