OS X 10.9 Mavericks and Cubase 7

From Steinberg: “*In case you are using Cubase 7 and want to update to OS X 10.9 anyway, please make sure to deactivate the “Display have separate Spaces” option in the Mission Control Preferences.”

I’m still on 10.8.5, but when I look at my Mission Control Prefs there is no “Display have separate Spaces” option. Perhaps the options are different in Mavericks??
