Have you tried contacting the app developer, either on this forum or on the app's website? He's known by the username cindori. He might be able to help you Time Machine regarding trim enabler and it works. Have you updated the app after having originally updated to 10.10.4? 'Cause as far as I know having trim disabled after a update to the operating system is akin to the old workaround instead of the newer, sanctioned way of doing so.
