I find it difficult to believe that you searched and found nothing. There is
already a thread discussing OSX and the new patch, only about six lines above this one. Second, had you read said thread you would have seen the direct link to the patch for Mac users, which should end with .tgz, not .package. Make sure you modify the url to fit the version you are updating from. Alternatively, you can use the launcher.
Moral of the story: search before you post. All of your questions are answered in the other thread.
