MacOS Could Not Be Installed on Your Computer: A Guide to Overcoming Common Issues

Are you experiencing issues with installing MacOS on your computer? Are you seeing a warning message that prevents you from opening an app or accessing certain features? If so, this guide is for you. We'll walk you through the steps to resolve common issues and ensure that your Mac is running smoothly.

Allowing Apps from Identified Developers

The first step in resolving MacOS installation issues is to adjust the settings under 'Allow apps downloaded from.' To do this, select App Store under the header 'Allow apps downloaded from.' Click the lock and enter your password to make changes. This will allow you to download apps from both the App Store and identified developers.

App Security Settings on Your Mac

In System Preferences, click Security & Privacy, then click General. Here, you'll see that the security and privacy preferences of your Mac are set to allow apps from the App Store and identified developers. Additionally, with MacOS Mojave, developers can have their app notarized by Apple, indicating that the app has been uploaded to Apple and passed a security check before being distributed.

Verifying Apps for Security

When you install Mac apps, plug-ins, and installer packages from outside the App Store, MacOS checks the Developer ID signature and notarization status to verify that the software is from an identified developer and that it has not been altered. This ensures that your Mac remains secure and protected from malicious software.

Why the App Store is the Safest Place for Apps

If you download and install apps directly from a developer or the internet, MacOS will continue to protect your Mac. Additionally, Apple reviews each app in the App Store before it's accepted and signs it to ensure that it hasn't been tampered with or altered. This ensures that all apps are safe and free of malware.

Gatekeeper: Ensuring Only Trusted Software Runs on Your Mac

MacOS includes a technology called Gatekeeper, designed to ensure that only trusted software runs on your Mac. This means that you can rest assured that any app you download from the App Store or identified developers is secure and trustworthy.

In conclusion, by following these simple steps, you can overcome common issues with MacOS installation and ensure that your Mac remains safe and secure. Remember to always prioritize security when downloading apps and installing software on your Mac.
