I've dealt with this bug as best I can through several upgrades. Its the issue where there is a sudden delay (monitoring) of something on the order of 500 ms. Well the final straw just happened. During recording, the recorded audio, upon playback were suddenly delayed on the order of .500 ms. I can't see how this is in anyway acceptable for a "Pro" application. How is it possible this is still going on? This problem has been reported by many. It isn't new or isolated. How can apple call Logic a professional application with this kind of random behavior? I'm using the latest version on a 2012 mac mini i5 2.5 ghz with 8 gb ram. I've heard the nonsense about you need an i7 and all this. There's no excuse for unpredictability without feedback whatever the case.
