If your getting the USB models you should be good to go... If your getting the standard 990/991 combo you'll need a 48v phantom power supply and an interface. Or you could just get a mixer with phantom power and usb to transfer to the mac.. That's what I did. I had a set of 990/991 mics awhile back as my first set and they worked well. I'm sure others can probably offer more help as I'm not as experienced as some when it comes to recording
