Last month, we reported on an issue in which some Mac users found that their computer automatically upgraded from macOS Monterey or Ventura to the latest version of macOS Sonoma, even with the Automatic Updates option turned off in Windows. system settings.
In many cases, it appears that users inadvertently triggered the Sonoma upgrade simply by dismissing a notification alerting them that the software update was available.
Unfortunately, macOS seems to interpret the action of clicking the X button to dismiss the notification as a green light to update to Sonoma, whether the user likes it or not.
Apple has no way of knowing why someone chooses to keep an older version or whether now is the right time to update. Therefore, this behavior is likely a bug, rather than Apple deliberately forcing users’ Macs to update. Fortunately, there is a way to prevent notifications from appearing until Apple fixes them.
If you’ve ever had to revert to Monterey/Ventura from a save because of the bug, or are worried about becoming the next unsuspecting Sonoma user, Jeff Johnson shared an easy way to disable “Upgrade to macOS.” Sonoma”notifications. Here’s how it works.
- Launch the Terminal app. You can find it in the Applications/Utilities folder. This will open a terminal window with a command prompt.
- Enter the following command: defaults write com.apple.SoftwareUpdate MajorOSUserNotificationDate -date “2025-02-07 23:22:47 +0000”
- Press Enter.
As Johnson notes, the exact date given is not significant, as long as it is in the future. The important thing is that once you enter the Terminal command, you will not receive update notifications before the expected date.
While this is an annoying issue, it’s worth noting that Sonoma has been available since September and has since received several updates to fix bugs and introduce the promised additional features. So if you have no reason to stick with an older version, it’s worth upgrading, if only for the security holes that Apple has closed since its release.
