The Macintosh desktop wallpaper has an interesting new 'color' selection — you can choose from a list of colors or choose the spectrum (random) option. This, for now, seems to only be an option with the Macintosh desktop wallpaper, not the other provided wallpapers. (And, great to see Apple using the Macintosh name — nice throwback!)
Password settings in Safari has a new popup directing you to the new Passwords application, then the tab self-deletes. BTW, the Passwords application can be found in /Applications. The Keychain Access application seems to have
disappeared.
