I have been looking for a certain pos software that is compatible with my mac computer system that I currently have right now. It has come to my attention that the best one for me is the Light speed pos software. After reading the different Lightspeed pos review online, I decided to buy it. It should actually be shipped out any day now, and I should actually receive it in about two days. I am quite sure I will not have a problem with it. Any problems may just be user error. But I think I have made a good reliable purchase.
