You need to compensate for Latency — and you haven't.

I don't know if ProTools can properly compensate for a USB mic plugged in directly to Core Audio—which will bypass PT's Mac drivers. With an interface, it is handling the signal coming from the DAW as well as the signal from the mic.

CPU load, buffer size, sample rate and processor speed all factor in.

In short. You need to know more about what you are doing.
