How to Disable Downloading of macOS High Sierra

If you’re among those who do not want to upgrade to macOS 10.13, MacPerformanceGuide.com has put together a quick guide to disabling the downloading of High Sierra. Check out the instructions below:

Open a Terminal window, and paste in the following, including the trailing quote character. (Note, you will need to head over to the original article to copy and paste the command properly):

What this does is create two small locked files with the same name as the installer and the temporary download filename, thus preventing macOS from downloading the installer into that location. There should be two locked files that look like this:

(Dummied-out placeholders forestalling download or install of macOS HighSierra.)

When and if the time comes to upgrade to High Sierra, simply throw these two files in the trash, then proceed with the upgrade.

  • Great article! This made me aware that I have a 5.21GB bloatware file on my laptop. Now I have to get rid of this before something wakes this bloatware up and makes my Adobe apps malfunction!!




  • Can’t remove the app neither rm or rmdir will kill it. Can’t unlock or change permissions on file.
    MacPro:Applications dad$ rm /Applications/Install\ macOS\ High\ Sierra.app
    rm: /Applications/Install macOS High Sierra.app: is a directory
    MacPro:Applications dad$ rmdir /Applications/Install\ macOS\ High\ Sierra.app
    rmdir: /Applications/Install macOS High Sierra.app: Operation not permitted




  • There is also other method to prevent automatic unwanted installations: disable it, installing manually.




  • I’m still running El Capitan on both my MacBook and iMac. I’d like to install Sierra on my MacBook first and try that out first. I’m having a problem finding the Sierra installer for some reason. I’m obviously not an “early adopter” if I’m this far behind, but I’d still rather bump up to 10.12 before going all-out with High Sierra. Any suggestions?




    • if you never downloaded macOS 10.12 sierra with your apple id in the app store before, there is unfortunately no chance after the release of a newer operating system to get older versions. I downloaded every release of macOS since 10.9, therefore I can download all versions since then again if I want to. as I said, if you never used your apple id to download macOS sierra at least once, you can only ask friends, who did it and download with their macs the installation package and copy it to your mac. furthermore for sierra you must use a special “hidden” link: https://support.apple.com/en-us/HT208202
