MacOS quarantine warning for SaxonCS 11

If you download SaxonCS 11 with a web browser and you're running a recent version of MacOS, you will get a warning that "Apple cannot check it for malicious software." This is just an indication that the release hasn't been signed by Apple. (Note that the SaxonCS 12 release is signed by Apple, so you will no longer get this quarantine warning.)

To work around this warning in the meantime, select "Ok" from the warning dialog, then open the Security & Privacy settings page and look on the General tab. You'll see a message that SaxonCS has been blocked. Press the "Allow Anyway" button. Then run SaxonCS again and choose "Open". You may have to do this several times, as MacOS will object to each dynamic library.

Alternatively, if you download the application with a command line tool, such as curl or wget, the malicious software warning will not arise. If you've already downloaded the file, you can disable the warning by removing the "" extended attribute from the file before unzipping it.
