Mac os 11 "libDlibDotNetNativeDnn.dylib" cannot be opened because the developer can not be verified

[Keith Hinkle]

Hi
I am getting the following error Mac os 11 "libDlibDotNetNativeDnn.dylib" cannot be opened because the developer can not be verified when running the following code on Visual Studio 2019 mac

Then I get the error Unable to load shared library 'DlibDotNetNativeDnn' or one of its dependencies

private FaceRecognition fr;
dir = AppDomain.CurrentDomain.BaseDirectory;

fr = FaceRecognition.Create(dir)

Thank you
Keith

I get the same error, building the FaceDetection sample on my M1 MacBook pro running 11.2.

@Webreaper if you find a solution please let me know, I am pulling my hair trying to solve this and I dont have much to spare lol

@Webreaper
You can use otool -L DlibDotNetNativeDnn.dylib and it should show missing dependencies.

However, I don't have M1 Mac machine and I may not reproduce your issue.

Here is what I got when I run the command

libDlibDotNetNativeDnn.dylib:
@rpath/libDlibDotNetNativeDnn.dylib (compatibility version 0.0.0, current version 0.0.0)

I dont know what I am missing

[Keith Hinkle]

@Webreaper were you able to make any progress on your end.

[Mark Otway]

No, I gave up and didn't continue investigating. Looking at alternative face-detection libs.

Have you ever find a solution about this issue? I have the same issue. I couldn't find a solution.

[Takuya Takeuchi]

I have no M1 mac. I can't go through issue.
But M1 mac support x86_64 by using Rosseta.
So it may work after install Rosetta.
