LEGO WeDo and Mac OS X Lion
I believe this is the current location for the Lion Patch

In the interests of finding it again when the LEGO group change their site again:


Visit the LEGO Education page.
Navigate to "Pre-school and School" -> Secondary -> 11+ LEGO MINDSTORMS Education -> Downloads (or similar)

I then filtered the list to just the Download Type of "Software Update / Patch".
