I tried the following:
- download��DrGeo.app-19.03a.zip��from the web browser, place it in Application and remove _CodeSignature; then it still appears as broken.
- download��DrGeo.app-19.03a.zip��using wget, place it in Applications and remove _CodeSignature: then it opens and asks for an image.

But if I open it I get an error related to libgit.

For��DrGeo.app-18.06a.zip��I get the warning that it is from an unidentified developer but it works fine if I place it in the application folder.

To sign an app you need to use MacOS as you need some xcode tool from what I remember.

Ok, one more thing that could be helpful to try and to give me
indication: remove the folder DrGeo.app/Contents/_CodeSignature and
start again DrGeo.app from the Application folder.

What OS X says?

Thanks
