Hello,
I am finishing up an app for OS X that needs to connect to the user's default audio output device set in System Preferences (among other things,
the app will play a sine tone for a selected frequency).
Everything works fine when Sandboxing is not enabled, but when it is, connecting to an external USB audio interface seems to fail when I
test it on my computer. These are the two violations I'm getting:
kernel: Sandbox: sandboxd: deny mach-lookup com.apple.coresymbolicationd
sandboxd: deny iokit-open AudioUserClientTascamUSBMKII (this is my USB interface)
I have set the following entitlements:
com.apple.security.device.usb -- true
com.apple.security.temporary-exception.audio-unit-host -- true
Do not post admin requests to the list. They will be ignored.
