I have Infini-D 4.5 for MAC also. Bought it as a "special" from MC for 1/2 price. They didn't tell me they were going to drop it a couple months later (that part was special). In any event, you may consider upgrading to Carrara 1.1 for a special (really) price before version 2 comes out. I belive the upgrade option may expire at that time.
