phone not visible to finder (on mac) suddenly When I connect my phone to my mac via usb, I no longer see it in finder.  Nor does it automatically launch iphoto as it used to.

On the other hand, I can see it from sdk tools like ddms, and can access the files that way (with usb debugging turned on, of course).  I can also see other android devices just fine.

Is there some setting that got turned off somewhere?

Try disabling Settings -&gt; Applications -&gt; Development -&gt; USB debugging in conjunction with setting Settings -&gt; Applications -&gt; USB settings to Mass storage.  If that doesn't work, and enabling USB debugging doesn't work, then I would assume it's an OSX issue.  You could try reinstalling the official drivers, if there are any.
