Navigating to System Preferences
The first step in resolving permission issues with Canon EOS Utility on macOS Big Sur (version 11.5) is locating the correct system settings. Apple reorganized several control panels in recent updates, which often confuses users who are accustomed to older versions of macOS. To begin, click on the Apple logo in the top-left corner of your screen and select System Preferences from the drop-down menu. Alternatively, you can open the Launchpad, locate the Other folder, and click on System Preferences.
Once the System Preferences window opens, look for the Security & Privacy icon. It typically features a shield graphic. If you do not see it immediately, you may need to scroll down or use the search bar at the top right of the window to type "Security" to filter the results quickly.
Unlocking the Settings Panel
macOS protects system-level security settings with authentication requirements. When you first click on the Security & Privacy pane, most options will appear grayed out or locked. You must unlock these settings before you can make any changes. Look for a small lock icon located in the bottom-left corner of the Security & Privacy window.
Click on this lock icon. A prompt will appear asking for your administrator username and password. Enter your Mac user credentials and click Allow. The interface should now become interactive, allowing you to modify application permissions. If you do not have an administrator account on the Mac, you will need to ask the primary user to perform these steps.
Granting Accessibility Permissions
Canon EOS Utility requires Accessibility permissions to interact with the camera's interface elements and manage data transfer processes. Navigate to the Accessibility tab within the Security & Privacy pane. This list contains all applications that have been granted or denied the ability to control your computer.
If Canon EOS Utility is not listed, click the plus (+) button at the bottom left of the window. Navigate to your Applications folder, find EOS Utility, and select it. Click Open to add it to the list. Once added, ensure the checkbox next to Canon EOS Utility is checked. If it was already present but unchecked, simply toggle it on. This action allows the utility to send commands to the operating system regarding camera connection and file management.
Enabling Full Disk Access
While Accessibility permissions handle interface interaction, Full Disk Access is required for EOS Utility to read and write image files to your hard drive. Click on the Full Disk Access tab in the same Security & Privacy window. Similar to the previous step, locate Canon EOS Utility in the list.
If the application is missing, click the plus (+) button and browse to your Applications directory to add EOS Utility. Ensure the switch or checkbox next to the application is enabled. Without this permission, the software may connect to the camera but fail to save images or preview thumbnails properly due to sandbox restrictions.
Restarting the Application
After granting these permissions, macOS does not always apply them instantly to running processes. It is crucial to quit Canon EOS Utility completely and reopen it. You can force quit the application by pressing Command + Option + Escape, selecting EOS Utility, and clicking Force Quit. Upon reopening, the software should now have the necessary privileges to communicate with your Canon camera without triggering security warnings.
Troubleshooting Persistent Issues
If the settings still do not resolve the connection problem, verify that you are using the correct version of EOS Utility compatible with macOS Big Sur. Sometimes, installing the latest update from Canon's website resolves underlying compatibility bugs. Additionally, ensure that no third-party antivirus software is interfering with the USB connection between your Mac and the camera.

Frequently Asked Questions
Why does Canon EOS Utility say I am not authorized?
This error occurs when the application lacks the specific Accessibility or Full Disk Access permissions granted in System Preferences. You must manually enable these toggles in the Security & Privacy pane after unlocking the settings with your admin password.
Do I need to reinstall Canon drivers after changing permissions?
No, changing permissions does not require a driver reinstallation. Simply quitting and restarting the EOS Utility application is sufficient for the OS to recognize the new privilege grants and establish a stable connection.
Can I grant permissions to EOS Utility via Terminal?
While some permissions can be managed via command line using tccutil, Apple strongly recommends using the GUI in System Preferences for Accessibility and Full Disk Access. Using Terminal for these specific settings can lead to configuration errors that prevent the app from launching.
What if Canon EOS Utility is not in the permission lists?
If the application is missing from the lists, click the plus button in the respective tab and navigate to the /Applications folder. Select the EOS Utility executable. If it still does not appear, ensure the app is not corrupted and try downloading a fresh copy from Canon's support site.
Does macOS Big Sur block Canon cameras entirely?
No, macOS Big Sur does not block Canon cameras. However, it enforces stricter privacy controls than previous versions. As long as you grant the correct permissions to the EOS Utility software, the camera will function normally for tethering and file transfers.
