Click the lock icon at the bottom left to have access to make changes.Click on the Apple Icon at the top left corner of your screen.To install Zoom or Zoom Rooms on your Mac computer, you may need to change your Security and Privacy settings to allow for apps downloaded from identified developers. So, you know, if any of you have found a way to get older operating systems in the App Store, be sure to comment and tell me how! And no, “maybe you should have thought of that before upgrading to Mojave” isn’t helpful, friends.The below instructions cover installing the Zoom application on macOS. I haven’t found a way to access Sierra or earlier, even when I’ve gone through Apple’s support pages clicking direct download links. One thing to note, though: If your troublesome computer won’t run High Sierra and you need an even older version of macOS, you may be out of luck. You don’t need to open it for troubleshooting on your old Mac, so you can just click “Quit.”Īfter everything is finished, you can follow the instructions in this Apple support article to create a bootable installer for your older Mac. You’ll get a warning after it’s done downloading that High Sierra is too old to be opened by Mojave, but that’s okay. Your Mac will ask you to confirm what you’re doing, and you’ll click “Download.”

When you click that link, you should end up at the App Store page for High Sierra.Ĭlick “Get” as shown on that page, and System Preferences will open and check for the update. To begin with, go to this Apple support article and click “Go to the Mac App Store.” Fortunately, there is a way to get around this and download High Sierra, at least. As a consultant who…you know… needs copies of these installers for work, this is a wee bit frustrating. The App Store’s “Purchased” page doesn’t show the operating system installers as downloadable options anymore, and searching for “High Sierra” (or “Sierra” or “El Capitan”) in the App Store doesn’t turn up any relevant results. Unfortunately, though, this is no longer possible in macOS Mojave. This was helpful if, for example, you had an older Mac that you wanted to troubleshoot or reinstall the operating system on you could then use that downloaded macOS file to create a bootable installer.

For a long time now, if you needed an older macOS installer (such as Sierra or El Capitan), you could visit the App Store, go to your “Purchased” page, and re-download anything you’d used in the past.
