Hi everyone, I'm on my first experience with a Mac OSX installation (Mountain Lion 10.8.5): I've made almost everything working on my Acer Apspire 5738G but i want some more from my ATI Radeon HD 4570.
I used some kext I found on a tutorial and a modified version of Chameleon (compiled by some guy named Peregrine, I guess). Now it is kinda recognized, but I think QE/CI is not completely working. Launchpad is totally unusable, new tab in Safari slows down the entire system and VLC doesn't play video due to Quartz Extreme absence.
In this pic there are some info about my video card:
(as you may see, it is recognized as a 4600, although it's actually a 4570)
By the way, I finally managed to make a triple boot working, so unless it's really necessary I would prefer not to modify anything about the bootloader (I tried Clover once, but it gave me so many troubles!)
Of course I checked this topic, but I didn't understand very much. What should be my first step?
Thanks in advance to whoever will help me with this!
