How to Stop Upgrade to MacOS High Sierra Notifications Completely on a Mac

If youre tired of the Upgrade to macOS High Sierra notifications nagging your Mac to install a system software update that you perhaps have made a conscious decision to avoid, then you will likely appreciate this tip to completely stop the upgrade macOS notifications. As you likely know by now, there is no way to really dismiss the Upgrade to macOS High Sierra alert, theres either an Install button which immediately attempts to install the update, or a Details button which launches into the App Store and also nudges you to install. Theres not a Never or Ignore option in the notification, which leads some users to believe there is no choice but to install the software updates presented. But thats not the case, you can ignore the update and also get rid of the notifications bugging you to update. Note this tip is specifically aimed at users who are not yet upgraded to macOS High Sierra and who specifically do not want to update to macOS High Sierra for whatever reason. This works on earlier versions of MacOS system software, including Sierra and El Capitan, and will likely work the same moving forward too. This trick can be useful even if you have gone about from appearing on the computer, because even after blocking the installer from downloading to a Mac, some users still may see the Upgrade to macOS High Sierra notifications pop-up. This involves modifying a system level file. You should backup your Mac before proceeding. If you are not comfortable modifying system items and do not understand related risks, do not proceed. Once the Mac has restarted, you will never see another Upgrade to macOS High Sierra notification again, as long as that .bundle file remains outside of the /Library/Bundles/ folder. And yes, note the file to move is called OSXNotification.bundle, not macOSNotification.bundle. macOS, Mac OS, Mac OS X, tomato, to-maht-o. Same same, but different. If you prefer the command line, you can use the following syntax to disable the Upgrade notifications by moving the bundle file to the user Documents folder. Because the command line requires precise syntax for expected results, using this approach is generally only recommended for more advanced users: Hit return and authenticate with sudo as usual, and then you can restart the Mac at any point to have the change take effect. This approach is the exact same as outlined from the Finder, except it is handled through the command line, but the effect is the same in that it will completely stop those Upgrade to macOS High Sierra notifications entirely from appearing on the Mac. If you ever want to reverse this so that you can be experience repeated Upgrade to macOS High Sierra notifications, then simply drag the OSXNotification.bundle file back into /Library/Bundles/ again, and then . Upon rebooting, the notifications to update macOS will return again. You can also reverse the process via command line as follows, assuming the OSXNotification.bundle file is in the ~/Documents folder. Hit return and authenticate as usual for the change to reverse. This obviously a somewhat dramatic approach, but if youre avoiding High Sierra for some reason or another then it can be a valid method to stop the update haranguing, whether on your own Macs, a relatives, or other Macs under sysadmin control or otherwise being managed. By the way, another much software and indirect approach is to place the computer into , but that will extend beyond just the system software updates and also stop all other alerts and notifications. This tip was found via on Twitter (you can too!), and appears to have been discussed recently from as well. Thanks to both of them for the trick idea!
