Genuine Fractals? Do you know the "endless argument" you've just started????
In the digital photo world, the only threads longer than "does Genuine
Fractals work best" are "Mac or PC" ;-)
OK, here is my experience. I received a free "limited time" fractals
software with something I purchased (scanner?). It was some strange setup,
worked for the first hundred conversions or something odd. I was not
impressed. It does a better job than PhotoShop at a big enlargement in ONE
step, true. But there are many simple PhotoShop actions (I like "Stair
Interpolation") that incrementally enlarge using PhotoShop's Bicubic method,
and to my eye do as well or better.
Stair Interpolation is free:

I believe actions are cross platform, this does work on a Mac.
The secret to them seems to be not increasing the file size more than 10% at
a time, so if you want to double the image size you go 10% (110% total),
then 10% again (121% total), then 10% again (133% total), then 10% again
(146% total).... you get the idea.
A second consideration is the source file. Scanned photos/film do not
digitally enlarge as well as digital captures (in my experience). I "assume"
this is because in a scan you not only have the image data, but the grain of
the film.
