Born Sleepy - Sam Deane's blog

In my recent post on OS X Helper Applications, I provided some sample code for installing and launching a helper application.

The host application and the helper communicated using distributed objects (NSConnection), running over mach ports (NSMachPort).

At the time, I was aware of the advice in [Apple Tech Note 2083: Daemons and Agents](http://developer.apple.com/library/mac/#technotes/

Following on from my Helper Applications sample project, I've created another sample which focusses on how to do code-injection.

In particular this sample makes and installs a helper application who's job is to inject some code into another application (by default the Finder).

I now have the registration for the bornsleepy.com domain, so in the next few days this site will be moving over to http://www.bornsleepy.com.

I've recently been looking at how to set up a helper application (one that either runs all the time as a background tasks, or on demand, potentially with system permissions).

Apple has a few samples in this area, but they're not all that complete, sometimes not cocoa-centric, and I found them a bit confusing.

After a fair bit of puzzling it out I've created my own sample (a modified version of a couple of theirs), and I've put it up on github in the hope that it might help someone else.
