Garageband for OS X needs 180MB compatibility update for Garageband for iPad

I’m reviewing Griffin’s Guitar Connect Pro this weekend. One of the things I wanted to test was copying a multi-track recording from the iPad to a Mac by downloading the tracks via iTunes to try to clean up my sloppy playing by quantizing the guitar tracks. Having never done this previously, I learned that the already up-to-date Garageband for OS X needs a compatibility update in order to import the tracks from its iPad counterpart. Note that the informational screen that popped up on my Mac specifically mentions Garageband for iPad. I have not tried this with Garageband running on an iPhone (which is a Universal app).
