Apple software updates application checks for updates way too frequently. Putting aside the Naziistic need to monitor us and control our systems, there’s far less need for updates than they would convince us. To slow down the update frequency, the command below was provided.
Open your Terminal from Applications/Utilities and SUDO in as an admin. Else simply run the command below and enter your OS password when promoted. The trailing number should represent the number of days between update checks. 15 may be too soon, but number is a personal choice.
sudo defaults write /Library/Preferences/com.apple.SoftwareUpdate.plist ScheduleFrequency 15
After running this command, the highlighted lines below appeared in the plist file. The next step is to check that Software Updates doesn’t change the frequency back, and obeys our whims.
