If you’re trying to install an application on your device and continue to receive this message, there are some steps you can take to get back on the right track.

For those that need the help, I m going to take a look at what they can do to try and resolve this installer encountered an error issue on their Mac. Additionally, the solutions are listed in the order of difficulty: the easier solutions are at the beginning, and the harder solutions are at the end.

While hopefully for most the issue only requires a simple fix, I’ve tried to cover the bases for those that really need to get into the nitty-gritty. I also answer some questions at the end concerning some of the more popular apps that experience this issue.

Covering the Basics

One of the first things you should try is rebooting your system. Performing a simple reboot may clear out any minor issues or bugs, and get you back to where you need to be. If a simple restart does t work, I would also consider shutting down the device, waiting ten seconds, and then booting it back up again.

You should also ensure that macOS is up to date. You can always check by going topple> System Settings > General > Software Update. Conversely, ensure that whatever app you are trying to install is available for Mac and that your machine meets the correct requirements.

Another important thing to remember is that since Apple switched to their own processors, moving away from Intel, you may want to ensure that the app you’re attempting to install does t need either Intel- or a Mac-based processor. Try to double-check this fact before installing.

Check the App

In terms of the apps themselves, you may want to check to see if you already have the app on your computer. While you’re doing this, you may also want to check the storage of your device as well. If you already have the app on your computer and are simply trying to update it, see if you are able to update the program through the app itself, or ensure that you are downloading the proper installer that will update your app. You can always check your storage by going toApple > System Settings > General > Storage.

You can check your Storage via System Settings

Check Internet Connection

Some users may also experience the Installation Failed warning due to a weak internet connection. While this is t true for all apps and installations, some apps may need a strong internet connection to complete the installation properly. Check your internet connection and try again.

Move the Installer File

Another thing that is really simple to do would be to move the installer from your Downloads folder to your User folder. For those attempting to install Microsoft Edge, this seems to work rather well for them, and it may work just as well for other applications.

Simply access your Downloads folder through Finder, and then move the installer to yourUsersFolder. The Users Folder is typically under Macintosh HD, or whatever you named your hard drive. Dragging and dropping will work best, but you could also Copy and Paste. This will leave you with two copies of your installer, however.
