This is not the mac thing what this is, is a addon that makes this alot easier...
Its called Supermacro what it does instead of having a limited of 225 characters to a macro extends that to 5000!
I tested this and you only have to press it once or twice and it WILL work and DOES work also can use it for many other things...
Heres link to addon: SuperMacro - Interface Additions - World of Warcraft Mods, Addons, and More!
The site scans it as it says.
Go have fun faking people off bridges ;D
