I have a question about embroidery software. I have a Brother PE780 and use a MAC. Does anyone know which software would be most useful for me to use? Will pay the price for the new Brother software if it s the best but wonder if there is something less costly. Also I wonder about USB drives can I use any drive if its the right size or do I need to have USB drives formatted to accept MAC? If so does the machine accept MAC usb? I am so confused...i. Are there MAC usb availble to purchase...Anyone know ? thanks Tina
