Yes and no: while a single specification covers all the standard
options, there are some characteristics typical of certain platforms.
For example the sequential arrangement of samples differs between Mac
and DOS/Windows versions (I don't remember exactly how, but it's
something like top-to-bottom-by-rows _vs_ left-to-right-by columns) --
although most professional graphics applications, Photoshop certainly
included, can recognize and deal appropriately with either platform's
'idiom'.

No. A TIFF is a TIFF is a TIFF; it's identical on Macs, PCs, Suns, Amigas,
mainframes, you name it.
What happens when you look at actual pixels on a PC? It should be 100%
pixel-for-pixel identical to the same image viewed at "actual pixels" on a Mac.
If you have an image that's not the same on both, email it to me off-list; I'd
love to take a look at it.
