Right, you could pull this into a MacAddress class, and use that:

describe MacAddress, " for 00-11-22-33-44-55" do
  it "should normalize to 00:11:22:33:44:55" do
    MacAddress.new("00-11-22-33-44-55").to_s.should == "00:11:22:33:44:55"

Then you can just do
@signup.mac_address = MacAddress.new "00-11-22-33-44-55"

and you don't really need to test that, of course, since it's just a setter.
