Hi, I am a macbook pro 2011 user who has replaced the optical drive with an SSD. I'm having trouble installing windows 7 from a usb stick and I have read that bootcamp 4.0.1 (which is only available for macbook air) has and usb stick install option. That's why I need macbook air user help : Could someone zip the Boocamp 4.0.1 app folder and sent it to me ? An user has done that for a mac mini and it worked. Thank you very much for your help.
