jvitordeoliveira Posted June 7, 2014 Share Posted June 7, 2014 Well, here is the thing: I have a sucessful Lion installation on my machine (used to have a Snow Leopard) without problems, and for some reason I'm not able to do the same thing with Mavericks(same problem with Mountain Lion). A instant reboot problem happens everytime I try to get to the installation screen (tried Distros, myHack and no luck at all, always the same problem). Funny thing is that even trying to install a VM of Mavericks it hangs on the Apple Logo and stays there. Does anyone know what could be the cause of this problem? I'll leave my pc specs below if it helps. -Motherboard: ECS G41T-M7 -Memory: 2x 4GB Kingsont DDR3 -Graphics: Nvidia Geforce 9600GT(planning to pick up a GT 660 this month) -Processor: Intel Core 2 Quad Q9400 Thanks in advance!:] Link to comment https://www.insanelymac.com/forum/topic/298609-cant-even-get-to-install-screenmavericks-and-mountain-lion/ Share on other sites More sharing options...
dcai777 Posted June 8, 2014 Share Posted June 8, 2014 Start with -x -v dart=0 for the installer. Leave a screenshot...

jvitordeoliveira Posted June 8, 2014 Author Share Posted June 8, 2014 Well, the first two pics are the outcomes on Mountain Lion and Mavericks,respectively( -x -v dart=0 ) . The last one was a what appeared after I tried lots of boot argument combinations. Everything I try to do still results in this weird reboot problem.... https://docs.google.com/file/d/0B9bO-LsMT6VXVk9yb1JHMnZCU00/edit Link to comment https://www.insanelymac.com/forum/topic/298609-cant-even-get-to-install-screenmavericks-and-mountain-lion/#findComment-2026990 Share on other sites More sharing options...
dcai777 Posted June 8, 2014 Share Posted June 8, 2014 Maybe try the amd kernel for now? Instant reboots are usually kernel related, but I have a Q6600 and the vanilla kernel works fine... Just try it temporarily... http://wiki.osx86project.org/wiki/index.php/Patched_Kernels remember to add the flag (ex. amd_kernel) Link to comment https://www.insanelymac.com/forum/topic/298609-cant-even-get-to-install-screenmavericks-and-mountain-lion/#findComment-2026999 Share on other sites More sharing options...
kvonlinee Posted June 8, 2014 Share Posted June 8, 2014 you can use myhack to make a usb instalation, sometime it need nullcpupowermanagement.kext in the usb installer. the boot with -v -x Link to comment https://www.insanelymac.com/forum/topic/298609-cant-even-get-to-install-screenmavericks-and-mountain-lion/#findComment-2027202 Share on other sites More sharing options...
jvitordeoliveira Posted June 8, 2014 Author Share Posted June 8, 2014 Tried AMD kernel(N1resh distro) and myHack without luck(again). I don't have a single clue of what could be causing this... Could it be a motherboard problem? It would be weird since my Lion install works with everything (Video, Audio, Network etc)... EDIT: If it helps, the reboot always happens after a quick "Args..." line appears on the screen.

dcai777 Posted June 9, 2014 Share Posted June 9, 2014 It shouldn't be caused by this, but does it work with integrated graphics?
