So as soon as i got OSX lion 10.7.4 up and running Apple released Mountain Lion. There was a previous thread for lion so I thought i would start up the mountain lion thread. I am having trouble with Multibeast/Rebooting without Unibeast. Here is what i have so far. 1. Installed OSX Mountain Lion.app to USB with Unibeast 1.5 2.Booted USB and Installed OSX Mountain Lion onto primary SSD with GUID option and named SSD "Macintosh HD" to be safe. 3.After it reboots I select SSD using Unibeast and load up OSX Mountain Lion. What works at this point. Detects my cpu and ram correctly at 3.39 GHz Intel I5 and 16 GB ram. ethernet port receives Ip buts its wrong and internet not working. back panel USB 2.0 ports. front panel USB 2.0 ports. power and reset switch. What doesnt work. HD4000 is not enabled so my resolution is 1024 X 768 with 64 MB ram using the DVI PORT Audio 892 back panel USB 3.0 ports front panel USB 3.0 ports internet. At this point I open up Multibeast 4.6.1 Lion Edition. What I need to know at this point is what should be selected in Multibeast and if there are others things I should install in addition to Multibeast install. (ex some other kexts/ chimera update) I am pretty sure that the audio will be 892 and that the ethernet I will use is Lnx2Mac's RealtekRTL81XX. Other than that i dont know. As always screenshots are welcome Hopefully the same guys who had this board with lion with join this thread and we can create a solid install guide for this msi board. Thanks to all that have helped make this possible. It has been a lot of fun reading the forums and threads thus far.
