This (your latest comment) would have been good information to include in your original post.
Based on that information, it's clear that the real problem here is that you're abusing NSTextField. The real solution is to rethink your UI conceptualization.
If your touch target (the text) is actually behaving as a button, then you can use a borderless NSButton.
If your touch target has slightly more idiosyncratic behavior -- it's like a button but NSButton doesn't do exactly what you want, or it's not like a button at all -- then you should be writing a custom control.
Keep in mind that "selecting the text" probably isn't your users' conceptual framework. They are probably thinking in terms of "getting details on that topic" or something of that sort. Translating that directly into a Cocoa concept such as a selected NSTextField is probably a little too reductive.
