Will steam (and portal) work on a MAC

[animeguitarist]

Basically, it's in the title. A friend of mine played portal at my house and would like to get it. However, she is on the dark side and uses a MAC. So, I thought I would check with you lovely people. Can the steam platform be run on a MAC and will Valve games work on it ie. half-life 2 and portal.

Thanks in advance.
