Okay, I'm shallow. I wanted Shockwave on the Mac mainly so I could play the old Snowcraft Snowball Fight game (it's not like Shockwave is particularly useful for anything else). So I downloaded and installed this latest version of Shockwave. Unfortunately, it appears to be rather more buggy than the Windows version. That game didn't work - and we're talking about a 10-year-old Shockwave application. Not exactly cutting edge...
