This is what happens when you try to run the Fuji installer for the 12MP Fuji X10 (which started shipping this month) on Mac OS X Lion. Same deal for the Fuji updater on the Fujifilm web site.
Since Adobe Camera RAW does not yet support the X10, I have no way of processing the RAW files that I have shot with the X10. Maybe some other raw converter works, I suppose.
So I downloaded the Fuji “RAW Converter... SilkyPix” application from Fuji, and it just reports “unsupported camera” for the X10 files. If Fuji wants to look incompetent, they’ve got my vote.
