You want:

to open a certain URL with a certain app.

Pardon the ignorance here if there is some (I'm fairly new to OS X
development)... If I registered my app with a special url scheme and then
sent the mailto url to my app, doesn't that just add an unnecessary hop to
the mix? I will already be inside my app clicking the mailto link, so I

If you’re observing an object, you should probably e

Yeah, I have strong references too, but some part of my NSURLSession code ends
up causing this error when we have a failure (SSL challenge) on a file download.
I'll have to implement the methods to handle the download failure cases, which
I am currently not doing.

Thanks. Yeah, I think I did suggest 1, once upon a time. Ugh. Guess it'll have
to do.
I kludged it by making my bound property an NSAttributedString and I set the
font on that when setting the value. Really gross, but got me past this hurdle.

Holy crap, don’t do that. First, you can’t stop a dealloc. Instead you’d have

Should say
That way the observed object cannot get deallocated before the observer.

I have a ton of observers in NSViewController subclasses.
Generally when I use an observer I make 100% sure I have a stro

Nope. Remember, objects don’t “nuke” themselves; they are dealloced when no
other objects have references to them
I'm having fun with async NSURLSession downloads but running into objects
deleting themselves in error cases while still being observed, resulting in the
lovely NSInternalInconsistancyException.
Is there a means to have an object know when it's being observed so that it
will refuse to nuke itse
Suggestion 1: A few weeks ago I ran into the same problem. I stumbled onto a
kludge that seems to work, which was to put some text into the text view in IB.
It can be spaces, it can be anything, as long as it's non-empty and it uses
the desired font. It seems that the bindings mechanism is th
