I'm the developer of SmashTunes (an app to control iTunes and Spotify). Since the latest beta of 10.13, I'm seeing a lot of errors being logged:
10759711: Error #17 (os/kern) invalid right attempting to add send right to port ( port:33051/0x811b rcv:1,send:0,d:0 limit:5).
AppleEvents: received mach msg which wasn't complex type as expected in getMemoryReference.
SmashTunes use ScriptingBridge for its communication with iTunes and Spotify. I'm suspecting this may have to do something with my entitlements file (which I think should be correct). The "funny" thing is, that the app is still functioning correctly (although a bit slow). So, the AppleScript is correclty executed by both Spotify and iTunes.
Anyone seen this before?
