The biggest problem is that audio isn't working. ALC887 is supported by AppleALC, and I put the kext into the right folder. Unfortunately it doesn't work.
My graphics AMD 6450 works OOTB on HS, but when i start the second monitor(HDMI), it clutters together with my main monitor(DVI).
And iServices, i logged into iCloud, the mail, contacts, photos syncs, but when trying to log in to iMessage, FaceTime and iTunes, i keep receiving errors.
For AppStore, whatever i attempt to download, it says "Please go to purchases page to download app." And it doesn't start downloading even i go to the page to click install.
And here is my EFI attached.
Thanks for any kind of help.
CPU: AMD A4-5300
