macOS security permission issue with custom DLLs in Unity and Mac Configuration in build settings

Using external DLLs in Unity on MacOS can lead to security permission issues due to Apple's strict security measures. Here's a step-by-step guide to resolving this common problem.
Verify the Problem:
Manually Allow Blocked DLLs:
Open System Preferences on your Mac.
Navigate to "Security & Privacy".
Under the "Security" tab, you might see a message at the bottom about the DLL being blocked. Click "Allow Anyway" or "Open Anyway" and enter password if asked.
Modify Gatekeeper settings: MacOS's Gatekeeper can prevent unidentified developers' software from running. To allow the DLL:
Open the Terminal (found in Applications > Utilities).
Type sudo spctl --master-disable and press Enter.
This command will allow apps to be downloaded from anywhere.
Now, try running the Unity project again.
After you're done, you should re-enable Gatekeeper with sudo spctl --master-enable to avoid any malware.
Check File Permissions: Ensure the DLL has the correct file permissions.
In Finder, right-click (or control-click) on the DLL file and choose "Get Info".
Under “Sharing & Permissions”, ensure that your user account has "Read & Write" permissions.
Review Unity's Plugin Settings:
In the Unity editor, select the DLL in the Project view.
In the Inspector window, make sure the appropriate platform (in this case, Mac OS X) and architecture (Apple Silicon, Intel-64) is selected for the DLL.
Ensure that the "Load on Startup" and other pertinent options are checked (should be enabled by default)
Update Mac Configuration:
In Unity, navigate to Edit > Project Settings > Player.
Scroll down and click on Other Settings
Scroll down again to find Mac Configuration section
Update the Mac Configuration section (follow the below Screenshot)
