Fixed - Can't open Apps Error on macOS Sequoia !

If you're encountering the "Can't Open App" error on macOS Sequoia, it usually relates to app security settings or installation issues. This problem can occur whether you've downloaded the app from the App Store or installed it manually from a DMG file or external source. This tutorial walks you through both scenarios to help you resolve the issue and successfully open the app. If the app was downloaded from the Mac App Store and still won't open, the first step is to uninstall and reinstall it. Open Launchpad, find the app, and drag it to the Trash. Then return to the App Store, search for the same app, and reinstall it. This often clears up any corrupted data or failed permissions from the initial installation. For apps downloaded outside the App Store—such as those in a DMG format—you might face restrictions due to macOS's built-in Gatekeeper security. In these cases, you'll need to manually allow the app to run. Open System Settings, then navigate to "Privacy and Security" from the sidebar. Scroll down until you find a section that mentions the blocked application. You should see an option that says "Open Anyway." Click it to override the system warning. Make sure your Mac is set to allow apps from both the App Store and identified developers. Still within the "Privacy and Security" section, look for the setting labeled "Allow apps downloaded from" and select "App Store and identified developers." This allows macOS to open apps from verified external sources without blocking them by default. Once these steps are complete, go back to Finder or Launchpad and try opening the app again. You may receive one final confirmation prompt from macOS asking whether you're sure you want to open the app—click "Open" to proceed.
