macOS: How to request microphone access?

[tresf]

Question

Why won't Java ask for Microphone access? How does one package a Java application so that will properly ask for permission to use the microphone?

Please see the following unit test: https://github.com/tresf/SoundRecorder.

Test	Pass/Fail	Details
Terminal	✅ PASS	javac SoundRecorder.java && java SoundRecorder, from Terminal, it works. Reset with: sudo tccutil reset Microphone com.apple.Terminal
IntelliJ	✅ PASS	From the Project Explorer, Right Click SoundRecorder.java, Run. It works. Reset with: sudo tccutil reset Microphone com.jetbrains.intellij.ce
Bundle	🚫 FAIL	./package.sh, double-click SoundRecorer.app. It doesn't work.

Passing criteria:

• MacOS should prompt for permission to access the microphone, the resulting .wav file should contain audio, not silence.

Some initial observations:

• Failing tests produce a silent .wav file for the specified duration. No prompt; no Java exceptions thrown.
• Successful test show the parent app, not Java. e.g. "IntellIJ would like to access the Microphone".
• You only get one chance to Approve. Dismissing the dialog will assume "No" and the option will need to be manually added using System Preferences, Security & Privacy, Privacy, Microphone.
• Unlike other macOS privacy settings, there's currently no way to manually add an App to the Microphone area.

Java version tested:

• AdoptOpenJDK 11.0.10
• API: AudioSystem.getLine(...).open(...)

Some general questions:

• Are entitlements required for Microphone access to work?
• Can entitlements be applied to a non-binary (e.g shell script) executables?

Some general questions:

• Are entitlements required for Microphone access to work?

This Unity thread suggests they may be needed:

Quoting:

We discovered that in addition to ensuring NSMicrophoneUsageDescription
was in the plist in the mac app bundle package Contents when built, these entitlements also needed to be set:

com.apple.security.device.audio-input
com.apple.security.device.microphone

Then the signtool must be run (and a cert may be required)

... however signing with these entitlements alone doesn't seem to fix the symptom.

We are marking this issue as stale because it has not been updated for a while. This is just a way to keep the support issues queue manageable.
It will be closed soon unless the stale label is removed by a committer, or a new comment is made.
