    Now i am on Mavericks :-)) most works fine: I used MyHack to create an USB Stick with the downloaded Installtions Files. I only modified the USB Kext to boot :-) after boot Problems i used the USB 2.0 Kext which helped me with my ML installtion. I removed from the Stick IOUSB.kext and IOUSBFamily.kext in the Folder System/Library/Extentions/ and copied the USB 2.0 to that location. I installed Mavericks over the ML installation, no clean install, so the drivers are working fine :-) I only installed Sound Kext and need PowerManagement Kext because Battery Symbol is shown but doesn't show the battery level. Webcam doesn't work need to find out what Kext must be installed :-( My Edimax Nano Wifi Dongle works great. Sleep hangs need to install some kext.

    Okay i doesn't know that. But the orig. Hardware is for me the better way, if i should sell my notebook after some years. Edimax deliver driver for ML thats work perfect :-) the kext are a beta but couldn't find any bugs for now.

    This week i received my Edimax Wifi USB nano Dongle EW-7811Un but i tried orig. driver from edimax and the chipset driver from realtek both doesn't work :-( think i should switch back to USB 2.0 i have read the hole thread but didn't find the right kext for USB 2.0 devices. Only Super Speed 3.0 is working :-(

    Dell Inspiron 17R Notebook (Inspiron 7720) - Can run Mac OS X

    after some tests i decided to reinstall my osx :-) and now all important components are running fine so far. some tipps after that. i used iAktos ML2 because i have no pure osx ml image. first installed iAktos on an USB stick after that the installation aborts with the known error no root device, a fix for that is really easy remove the usb kext from the folder s/l/e on the USB Stick and copy the USB 2.0 kext to that location. you don't need a mac for that i have a netbook with snow leo but i used Transmac under win 8 for that works perfect. The change from the USB kexts are necessary because under the setup in iAktos the 3.0 USB get lost. Now iAktos is running without errors :-) then i used disk management to create an hfs partition before that it is the best to use easeus partition manager to create a linux partition which the osx disk management can reformat for hfs journaled. important is the next step under customize!! dont choose sound or nic or any graphic card only under the nvidia section is part that removes the nvidia kext to a temp folder that should be choosen to avoid boot problems. if you do like i describe you avoid trouble with double wrong kext for nic sound and graphics. don't choose battery or monitoring kext!! that creates boot problems. only choose ps2 for trackpad the necessary kexts are installed after the setup.

    Hallo, my system: 10.8.2 OSX ML used iAktos ML2 installed all kext. After copying the DSDT.aml to my extra folder the graphics Card is shown correct HD4000 but only 384 MB i have read the full Thread but the last fixes are only for 10.8.3 or 10.8.4!! What works: Bluetooth inkl. Network with Tethering! Realtek NIC works good too WebCam is fine Keyboard incl. lighting via F Keys Trackpad USB Logitec Touch Mouse Display brightness Control via System Settings not via F Keys My Boot Loader is Chameleon not Clover! Clover injecting doesn't help me! What makes trouble: Flash Videos screen is black :-( newest Flash Player is installed all Videos on Websites are flickering :-( Java is installed too no Sound :-(( Battery Symbol only working when booting with the -f flag but then the trackpad doesn't work! Seem the wrong battery kext is loaded, how can i fix this. Sleep doesn't work too :-( Kext Manager inside OSX is running so far Kext Wizard doesn't work isn't showing my OSX Partition :-( Help would be great :-)) Looked out for an unlocked Bios A15 because my system shows the nvidia as unknown too kexte are not loaded i removed all i have an 3630 System so unlocked Bios ends in a brick i have read :-( Is it possible that the smbios deliver wrong informations for OSX? Videos doesn't run tried vlc result in an error quartz graphic accelleration not working Any idea for the sound and video problem? It would be great get the last things working

    So after some trouble with my usb Stick ML is running with some questions...i installed it with iaktos ML2 USB Stick removed the USB Kext which makes trouble "no root device" after that booting fine :-) installed all Kext from this thread but couldn't find the dsdt.aml in the extra folder. I manually copied the dsdt.aml after that i got a system error. Removed system boots again. My problem the Graphics are running on the right resolution but without the correct graphics adapter shown as unknown. Sound doesn't work too. Bluetooth works fine i use my smartphone with bluetooth tethering to get an internet connection. no need for buying an wlan adapter :-) keyboard works fine too. trackpad is ok too. are there any kext for the HD4000, or for the sound chip? DSDT.aml i have no idea. I need some help to get the rest working.
