You need to save the nib file in the new nib (10.2) file format to be
able to store the properties introduced in 10.2 and later. Note that
there was a bug in this file format prior to 10.2.6 - resave nib files
created in the new nib file format prior to 10.2.6. PLEASE look in the
list archives for a lot of discussions on this topic.

2. I've tried setting the NSProgressIndicator to disappear when it is
done. Or if I can't do that, I'd like it to fade somewhat, like in
Omniweb. I might have missed something, but there doesn't seem to be
an option in the Apple dev pages to make it disappear or turn all
gray. There is an option in Interface Builder, but it doesn't seem to
be working properly.
The same thing holds true here - properties set in IB for post 10.2
features (isDisplayedWhenStopped) will be lost if nib is saved in pre
10.2 nib file format. You should still be able to set these properties
in code (awakeFromNib: is probably a good place) if your running on
10.2 or later and for some reason aren't able to use the new nib file
format.
3. In the Apple Dev pages, it indicates that several of these features
are meant for OS 10.2. Will some of these still work in 10.1? It
seems like in 10.1 it was two rotating arrows instead of the spinning
circle.
The features that are new for 10.2 will only work in 10.2 and later.
Simple as that. The spinning arrows were never available in Cocoa -
only in Carbon. Unless you count the implementation of spinning arrows
that Omni provided (provides?). If you need to write code that works on
both 10.1 and 10.2 the list archives contains a lot of info on that
topic too. There are also a couple of tech notes at ADC that you should
peek at.
