just followed some of the normal steps i could find on the internet. there is a good youtube video about installing on the 7520. just search online and on some of the normal forums, the computer runs great. the only problems i have are: 1. Power Consumption (90 min on battery) 2. ATi 7730 won't work 3. Integrated Wifi card won't work (thinking of replacing it with a different internal card) 4, Sleep won't work Can any one lend a hand?

i have the same laptop only i upgraded mine, 16GB ram 128GB Samsung 840 Pro SSD removed cd rome and placed the 1TB hard disk there. using an external wifi card. I'm running os x 10.9 for the past month or so. using mainly Graphic Applications such as Photoshop, Illustrator, InDesign and some video editing (Premiere,After Effect) and Appeture. its running smoothly on the HD4000 though i would really like to get the ATI to work, the system recognises it but i can't really use it. it has 2GB DDR5 which will benefit me a lot when i run complex stuff. any one has a solution? i don't care about battery life since when ever i use it I'm connected to an outlet and if i would realy want good power consumption i would just dual boot to win 8. Any help would be much appreciated. Thank You!
