- Product
- Adobe Applications
- Device & OS
- macOS
- Scenario
- Attempting to install or open an Adobe application downloaded from the internet on a newer MacBook Pro.
- Observed behavior

Ensure your MacBook Pro is connected to a stable internet connection for re-downloading files and verify that you have administrator privileges to modify system security settings.
Re-download the Official Installer and Adjust macOS Security Settings
This solution resolves issues caused by corrupted downloads or macOS Gatekeeper falsely flagging the Adobe installer as damaged.
macOS has strict security protocols that prevent unverified or partially downloaded software from running to protect your device. Re-downloading the correct version and allowing it through System Settings usually clears the error.
Locate the problematic Adobe installer in your Downloads folder, drag it to the Trash, and empty the Trash to prevent confusion.
Visit the official Adobe website to download the installer again. Ensure you select the correct version for your Mac's processor (Intel or Apple Silicon).
Click the Apple menu in the top left corner and select 'Restart' to clear any temporary system caches.
Go to Apple menu > System Settings > Privacy & Security. Scroll down to the Security section and ensure 'Allow applications downloaded from' is set to 'App Store and identified developers'.
Double-click the freshly downloaded Adobe installer. If a prompt appears asking if you are sure you want to open it, click 'Open'.
Remove the Quarantine Attribute via Terminal
Use this advanced method if you are certain the file is legitimate but macOS Gatekeeper continues to stubbornly block it.

Frequently Asked Questions
Why does my MacBook Pro say the Adobe app file is damaged?
This warning typically occurs when the download is incomplete, gets corrupted during the transfer process, or when macOS Gatekeeper blocks the file due to an unrecognized or missing developer security signature.
How do I know if I need the Intel or Apple Silicon version of the Adobe app?
Click the Apple menu in the top-left corner of your screen and select 'About This Mac'. If the Chip section mentions Apple M1, M2, or M3, you need the Apple Silicon version. If it says Intel Core, download the Intel version.
Will deleting the damaged installer remove my existing Adobe files?
No. Deleting the downloaded installer file from your Downloads folder or Trash will not affect any Adobe applications that are already successfully installed, nor will it delete your personal project files.
Can I completely disable Gatekeeper to install the app?
While it is technically possible to disable Gatekeeper via Terminal, it is highly discouraged for security reasons. It is much safer to allow specific apps through the Privacy & Security settings or by clearing the quarantine attribute for just the affected file.
