How to view RAW from Canon 5D mark III for OS 10.6

To 'Preview' RAW files from Canon 5D mark III, it is known that you need to install the Digital Camera RAW Compatibility Update 3.12 , but it can only be used with iphoto 9, which in turn only work in OS 10.7, so there is no way for 10.6 users to 'Preview' the RAW files? Please help if you no any other ways, thank you!
