Tony_555 Posted July 1, 2011 Share Posted July 1, 2011 Hello. I have followed the LifeHacker tutorial to get OSX working on my Corei7 computer. It uses iPortableSnow so I can boot from a USB drive. Originally, when I tried to boot into OSX, it would just shut down my computer. I then typed: cpus=1 -v -x -f graphicsenabler=no maxmem=4087. This seemed to work and I have now successfully booted from the USB into OSX. OSX seems to be running fine and I can open and run programs. However, when I try all this the next day and try to get into OSX again, the computer just shuts down. It says something about CPUs and then says it is safe to shut down the computer (and then shuts down by itself). I am doing the EXACT same thing I did when I first booted in. Eg. Same USB, same text typed in (cpus=1 -v -x -f graphicsenabler=no maxmem=4087). It seems that every time I boot in for the 2nd time, I have troubles. Does anyone know what is going on???

ifrit05 Posted July 1, 2011 Share Posted July 1, 2011 Try to boot without that much boot flags. Try just -v (verbose mode). You don't need to boot with -x (safe mode) or -f (force reload caches, it will take forever to boot). Maxmem isn't needed either, also try to boot without cpus. When you boot with -v, see what error it stops on and tell us here.

When you boot with -v, see what error it stops on and tell us here. Post your specs. Like said above try only -v. Make sure standard stuff is enabled in your BIOS also (ACPI 2.0, AHCI). Sounds like an issue with your CPU. Link to comment https://www.insanelymac.com/forum/topic/261238-2nd-boot-failed/#findComment-1707007 Share on other sites More sharing options...
Tony_555 Posted July 2, 2011 Author Share Posted July 2, 2011 Thanks for your replys. I have added my specs in my signature. I tried just using -v and it still shuts down my computer. Here are the last few lines of code: Can't initialize disk cache /dev/rdisk1s1 (hfs) EXITED WITH SIGNAL 8 fsck failed! Kext loading now disabled Kext unloading now disabled Kext autounloading now disabled Kextnel requests now disabled Can't get kextd port syncing disks...Killing all processes continuing done CPU halted: It's now now safe to turn off your computer. I have tried using the mach_kernal (I read somewhere that this is good for an i7 CPU). However, when I use this, the computer just sits on a light blue screen forever (after going through the OSX registration screens).

Noam AA Posted July 2, 2011 Share Posted July 2, 2011 you need to provide more details Specs, installation method... osx version? are you using patched DSDT?

OP, first thing you want to do is go into your BIOS, and enabled AHCI. There should be something that says like "Sata RAID/ AHCI mode" or "Configure SATA as". After that boot with these flags only "cpus=1 busratio=20 -v". If that doesn't work add an "-x". You were missing "busratio=20" in your boot flags, that was most likely the problem if you didn't already have AHCI enabled.
