Tooltips on NS couldn’t use colours before that change.

What happened is that tooltips set the background to yellow and left
the foreground (text) to be the system default (black).

MacOS Mojave has introduced ‘dark mode’, which makes the foreground
colour light, and therefore we’re seeing light text on a yellow
background.

If you don’t want to apply the above commit the absolute minimum fix
for emacs-26 would be to explicitly set a foreground colour for
tooltips, or not set the background, therefore reverting to the system
default.
