just curious....what version of Final Cut do you have? The latest version of Final Cut Studio found here

has all you'll need. Even final Cut Express (much less expensive and scaled down version) has a lot of great features to create a fantastic slideshow. The Studio version has every feature that can imagine and you can make some amazing presentations with it. It includes DVD Studio 4 which only comes with the studio version. You can create some hi-def slideshows with that program. Although if you don't need all of the advanced features of Final Cut Studio, Final Cut Express has every feature that ProShow Gold has. What I have found since switching to a Mac was that instead of having one stand alone program for photo editing, layering, animated titles, and smooth transitions for slideshows , you have to use multiple programs to accomplish a beautiful end product. But once you learn more about editing, authoring, and lay-out, the Mac is workhorse and can handle whatever you got! Finalcut Express has about everything you need. I remember creating a slideshow for a family reunion with ProShow Gold. It would freeze my pc up time and time again. Then I would get lucky and it wouldn't freeze...but when I went to burn my dvd creation, it would have issues burning it. In fact, the family slideshow I made ran an hour and 10 minutes. After 5 attempts to burn my show, I told myself this was the last time...and it burned. Two weeks after my reunion, I bought a Mac. I was very surprised that there really wasn't a stand alone program like P.S.G. for a Mac. What I realized was that it was because Mac users want to be able to control it more. Put their twist on it. Basically to really be able to take it to the next level. I've learned to do that now. I tried Fotomagico and it was a nice program. As you said, it didn't have some of your favorite features that p.s.g. has. You are correct...it doesn't. But you can edit you photo's before the slideshow in Photoshop and then bring them into the Fotomagico program. I'm sure you have tried Photoshop. It is limitless. I also want to add that Apple has a great emulator program called VMware Fusion 2. here's a link to it

I have heard that this program works great with running Windows program on an Intel Mac. I personally have never used it but I have a pal that works in the graphics arts business and runs some major Windows graphic programs on his Mac with this program. I think it's worth a shot if you are dead set on ProShow Gold. If you decide to go that route, I'd be interesting in hearing how it worked for you. I hope all of this info helps.
