Community member Phil D has reported the following;
“If you’re getting clients complaining the mixes are right heavy when they aren’t, ask them if they are listening on headphones via a recent MBP. If they are, tell them to go into Audio Midi Set Up and click on the Built In Speakers section and make sure the balance is set correctly. It looks as if a lot, if not all 2011-2012 MBP are for some reason set with the left side a few dbs lower than the right.”
Nice find Phil. With more and more of us using laptops this us a really helpful find.
