iTunesTrack location is nil in sandbox mode? - macos

Question

I am sandboxing an osx app that uses scripting bridge to access iTunes.
for(iTunesFileTrack* track in fileTracks)
{
//url is nill in sandbox mode but good value in non sandbox mode
NSURL* url = [track location];
NSString* sourceFile = [[track location] path];
if(sourceFile == nil)
{
NSLog(#"Sourcefile for the track %# was nil", track);
continue;
}
}
nil is returned, I am using following entitlements
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

</plist>
The console shows following violation
iTunes[1592]: AppleEvents/sandbox: Returning errAEPrivilegeError/-10004 and denying dispatch of event core/getd from process 'TestiTunesAccess'/0x0-0x4d04d, pid=1789, because it is not entitled to send an AppleEvent to this process.
it works fine in 10.7 and location is returned OK, but in 10.8 and 10.9 because the scripting-target entitlement is active, I can iterate the library but location of track is nil, why is that so ? if I just use temporary exception and remove the part:before10.8 then it works.
But since apple recommends we use scripting target in 10.8+ and not temporary exception entitlements, I am using the recommended ones. any help would be highly appreciated.

Answer 1

I fixed this by adding a temporary exception for iTunes, as shown in this answer.
<key>com.apple.security.temporary-exception.apple-events</key>
<array>
<string>com.apple.iTunes</string>
</array>
