i need to load raw images from Fuji X10 into Iphoto/Aperture. Any help?

The raw format Fuji X10 is not (yet) supported by Aperture and iPhoto, sorry.

See the list of supported raw formats: Apple - Aperture - Technical Specifications - RAW Support

As a work-around, use the software that came with your camera to convert the raws to another lossless format - tiif or psd. Or try, if Adobe's frre DNG converter supports your camera. Then you could do the raw processing in iPhoto or Aperture after importing the dng files.
