I suspect that there are a lot of schools out there running old Mac software also, so making the software run only on the new Macs is cutting out a lot of users (particularly in the less-wealthy school districts). They’ve made their software so that it only runs on Mac OS 10.7.3 or newer, but my MacBook Pro is running OS 10.6.8. I downloaded the software from, but was unable to run it. It looks like I won’t be playing with the bridge-design contest software this year.
