I am having Samsung Chronos Series 7 Laptop.
Intel HD Graphics 4000
AMD Radeon HD 8800M(2GB)
8 GB RAM.
Resolution - 1920X 1080
i tried many times to install Yosemite, Sometimes it gets installed, but still i can find a proper Graphics resolution, or Even Audio and WIFI.
Followed every step, properly, and installed chameleon also following your steps for Drivers but it failed.
Any specific steps for Chronos Series. As i was able to install it on HP and Dell or May be Lenovo without any issues.
Please do reply.
