POS software for Mac

In My Humble Opinion
1

No, not that POS.

Point of sale software.

My brother runs a retail store and we have been kicking around with the idea of converting his computer network in his store to Mac, and I was wondering if anyone has had luck using any or knew of some to recommend.

Checkout is screamingly easy, simple and reliable.

More hard-core ones can be found on this comparison chart, but I personally have no experience with them.

Thanks for the quick reply!
