update to .7 cannot mount DMG files, no graphics
i updated to .7 last night and today i realized that i could not mount any DMG files. Pacifst did it again and installed some files into Extentions that i did not want to get installed. Therefore if you have this problem you need to replace System.kext with the previous version of System.kext you were runnning. I am currently running 8.4.1 System.kext.
Also if you lose graphics and have 915 like i do, delete all files in Extentions directory related to the 950 like AppleIntelGMA950*
I also had to revert to an older version of AppleIntelIntergratedGraphics kext
I hope this helps someone!
