necrono Posted December 21, 2009 Share Posted December 21, 2009 Hi, I have a 24" iMac, with OS X 10.6.2 installed. It hangs when it trys to start and shows the message panic (that in 5 languages, "You need to restart..."). I have tried holding C at startup to boot from DVD, but it hangs the same. I have done the test (holding D at startup), but everything is ok. I have tried safe mode but it hangs too. I have tried single mode and fsck -fy. Everything is ok. I have connected it with another iMac by firewire, and checked the hard drive from the disc utility of the new iMac. And everything is ok. I pushed the button repair anyway, but it did nothing. I have change the RAM, to see if that was the problem, but nothing. Now i´m lack of new ideas. I´m thinking of formatting the HD, but cause i can´t boot from the DVD, i´m not sure that´s going to change the situation. Looking the panic logs this is what i see: ***************************************** Backtrace continues...

ameris_cyning Posted December 21, 2009 Share Posted December 21, 2009 Maybe you should get a Mac, you wouldn't deal with this....wait, what? Back on topic, have you tried to boot with a 32bit kernel?

necrono Posted December 21, 2009 Author Share Posted December 21, 2009 Hi, how can you do that? Link to comment https://www.insanelymac.com/forum/topic/203265-imac-doesn%C2%B4t-boot/#findComment-1365415 Share on other sites More sharing options...
ameris_cyning Posted December 21, 2009 Share Posted December 21, 2009 Likewise, you can switch back to the 32 bit kernel by holding down “3″ and “2″ during system boot Source: http://osxdaily.com/2009/09/10/force-snow-...-64-bit-kernel/ Link to comment https://www.insanelymac.com/forum/topic/203265-imac-doesn%C2%B4t-boot/#findComment-1365470 Share on other sites More sharing options...

supermx3 Posted January 13, 2010 Share Posted January 13, 2010 maybe a reset to the pram and stuff Link to comment https://www.insanelymac.com/forum/topic/203265-imac-doesn%C2%B4t-boot/#findComment-1384014 Share on other sites More sharing options...
Memorial Posted January 13, 2010 Share Posted January 13, 2010 If it was actually boot from DVD, it shouldn't hang kernel panic. Clearing your PRAM will not really help (but you can try it, hold down command, option, P, R http://support.apple.com/kb/HT1379). Either figure out why it is kernel panicking and fix it. Or reinstall. Link to comment https://www.insanelymac.com/forum/topic/203265-imac-doesn%C2%B4t-boot/#findComment-1384023 Share on other sites More sharing options...
