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)
