I'm using an NSTextField to do the text drawing. It certainly renders text antialiased. In any case, the renderings do look antialiased; the edges are not sharply on pixel boundaries (see the top of the 5, for example). It just isn't the same appearance as in Instruments.
It's not the same anti-aliasing, either. The first one (Instruments) clearly has no sub-pixel anti-aliasing, while the other two definitely do. You may not have realized the significance of this, but I consider this strong evidence that Instruments is not rendering it as simple text. I think it's very likely to be rendering off- screen to fixed-size image-buffers, or using layers.
You can quickly approximate the appearance of no sub-pixel anti- aliasing by turning off LCD smoothing in the Appearance prefs pane, then quitting and relaunching your app.
You may also want to use the 'strings' command on the files in Instruments, to see if you can find the font-name anywhere. That would be evidence it's using the font, rather than sets of static images.
