Word for DOS (and Xenix!) predates Mac Word, and even the Macintosh itself, but Word for Mac predates Word for Windows by several years.

The DOS predecessor to Excel was Multiplan, which again predates the Mac, but Excel 1.0 was indeed a Mac-only product; Excel 2.0 was the first cross-platform version.

Another interesting example is Halo, which was originally planned as a Mac exclusive and introduced as such by none other than Steve Jobs during a Macworld keynote. Then Microsoft acquired Bungie while building up a stable of exclusive launch titles for the original Xbox, and it didn't see a Mac release until after the Windows version shipped a couple years later.

Halo was never going to be Mac exclusive. It was going to be Mac/Windows like Bungie's other recent stuff at the time like Myth II. It was introduced at Macworld but it was always intended to have a Windows version.

Kid Pix, Sim City, Myst and Photoshop also come to mind.

Was there anything like the After Dark screensaver on Windows before it exploded on the Mac scene?

I remember the Halo demo in the keynote.

I’ve also had a product I worked on in a keynote by Jobs. A nervous time.
