If Apple’s Logic Pro is misbehaving, there are a few quick things you’ll want to check. Naturally, the first is that your hardware meets the minimum system configuration. In OS X, you can choose Apple > Software Update and make sure you have the most recent version of Logic Pro and QuickTime. If you’re using a third-party sound card, audio or MIDI interface , storage system, plug-in, or control surface, go to the manufacturer’s Web site and make sure you have the latest versions of the appropriate drivers or other software. Believe it or not, in the majority of cases, this will solve the problem, as Logic Pro is remarkably user-friendly.
