Hey! I'm new here but I did manage to install Yosemite zone onto my acer aspire m5 laptop. I just partitioned by ssd inside and installed it onto one partition. Everything seems to work okay other than the wifi. I have tried all kinds of KeXT but I can't figure it out. It has a broadcom 43xx chip in it along with a realtek chip. And please don't suggest external adapters. Thanks so much!
