MatterControl and USB power draw

Hey all,
I recently moved from Repitier-Host over to Matter Control and since the switch my Mac (OSX 10.9.4) is disabling my USB ports for “drawing too much power”. I can’t for the life of me figure out why the new software would be connected to this but after running hardware checks on both my Arduino MEGA and my MacBook Pro I can’t come up with any recent changes to my rig except that. Any ideas?

How does the printer perform when connected to a different computer?
