Ok, that makes sense. I had assumed that all apple supplied libraries would allow the use of the dot-syntax and properties....silly me.

NSStatusItem defines:

- (BOOL)isEnabled;

(not -enabled).

Can someone explain to me why enabled does not exist in the NSStatusItem.h

The implementors chose to store the information somewhere else.
The implementation detail should not be a concern to you -- you should be using the public API (maintaining encapsulation).



and why NSStatusItem.h does not use @property for its properties?

It precedes the introduction of properties. Most classes have not been retrofitted.

In general, you are encouraged to use the dot syntax only with actual properties...
