Mac Forums

i am a bit of a designer and i have already tried i web but i am looking for a web design software that would allow me to create a lot more complex designs. is there a software for mac that i can use that would be easy for me as a beginner but having the same advantages as macromedia dreamweaver? would really appreciate your help. as i don't want to rely on my web designer anymore, who is not giving me the kind of creativity i need for my web's look and feel. thanks so much!
