Installed Mojave, tried the Dark Mode, switched back to Light, but the dialog boxes and warnings are all weird and gray. Is this the new normal look for Mojave in Light mode? Tried restarting, activating and deactivating reduced transparency, tried different accent colors, deactivated Night Shift, can't make this look normal again. Notifications are now black on dark gray text. Left pane of Messages app is grey while the right pane is white. Drives me crazy. iMac 5K 2015. Thanks for your help.
