Undo in Gradients doesn't show in gradient editor...

...but is happening to the gradient in the Inspector.

Difficult to see, as gradient inside inspector is small, and often covered up by the gradient editor whilst editing a gradient.

MacOS 10.13.6

Latest Unity beta

Using Unity colour editor and gradient editor, not the Mac ones.

Works for me. Could you please submit a bug report with a video of what is going on?
