I'm currently on assignment in Italy and I left my canon CDs back home in the states! I have a Powershot S50 that I broke over the summer...it finally got fixed and mailed to me here in Italy (thats why the CD is back home). In the mean time I am now a Mac user and to be honest who needs the canon software ?? iPhoto and OS X do such a good job I never missed the software - until now. I just got back from a weekend skiing where I used the panorama function a lot....but I do not have the stitch assist software on my powerbook - oops. I checked Canon's website - no luck. Are there any other options? Otherwise I'll do it manually in Photoshop.
