How to: Set OS X Mountain Lion Software Update Frequency

30 August 2012 2,220 views 4 Comments

With a little tinkering, you can get back a feature Apple took away and set OS X Mountain Lion software update frequency…

Apple removed the ability to set Software Update frequency in System Preferences — now it automatically checks once a week, every seven days. However, with a little tinkering, you can set OS X Mountain Lion software update frequency from one to seven days.

Of course, you can manually click the “Check Now” button in System Preferences or via Software Update under the Apple menu. However, we didn’t buy Macs to be the monkey pressing a button, again and again.

Set Mountain Lion Software Update Frequency

In the Finder, while holding down the Option key, select Library from the Go menu. In the Library folder, locate the Preferences folder and open com.apple.SoftwareUpdate.plist in TextEdit or Xcode — therein, change the ScheduleFrequency key from 7 (days) to 1 (day), or any number in between, and then save (.plist).

Alternately, you can do this voodoo via Terminal, as well. From the Finder > Applications> Utilities > Terminal and typ or copy/paste:

sudo defaults write /Library/Preferences/com.apple.SoftwareUpdate ScheduleFrequency 4

Again, the business end is the schedule frequency, which you can set from 1 to 7 days.
