Set Software Update check frequency in Mountain Lion

Mountain Lion removed the ability to set the frequency of checks for software updates. The default frequency was always a week and it remains so.

To change the frequency, open com.apple.SoftwareUpdate.plist, found in /Library/Preferences, and change the ScheduleFrequency key from 7 to the number of days you prefer.

I prefer to be notified of updates daily, if available, so I changed the frequency to 1.
