What tv show did Zac Efron not appear in?

That's a tricky question! Zac Efron has been in a lot of TV shows, so to answer definitively, we need to know what kind of shows you're thinking of.

Could you give me some more information? For example:

* What genre of show are you interested in? (e.g., comedy, drama, reality, etc.)

* What time period are you interested in? (e.g., his early career, recent work, etc.)

Once I have more context, I can give you a more helpful answer!
