crude7435 Posted July 30, 2007 Share Posted July 30, 2007 I installed OSX a year or two ago, when the newest was 10.4.3. I decided to give it a try again on my laptop. I just finished installing OS X 10.4.8 JaS Intel version. The installation went very smoothly. The computer restarted after installation, the gray Apple screen comes up, the little pin wheel turns for 20 seconds or so, and then it goes on to act like it is going to boot up. Then the screen turns off, turns on but is still black, turns off again, then tuns back on but is still black. I can hear the computer reading from the harddrive and I know the computer isn't hung, but there is no display. Any solutions? Thanks InsanelyMac people!

crude7435 Posted July 31, 2007 Author Share Posted July 31, 2007 I know this is probably a dumb question, but how would I go about booting up to the "-v -s" like it says?

boinkytwo Posted July 31, 2007 Share Posted July 31, 2007 when you see darwin loading.. hit enter or f8.. you will be prompted at boot: so you have to type after the boot: it would appear like this below boot: -v -s then hit enter. youll see some scrolling text, and will stop soon, and youll see some of the following: /sbin/mount -uw/ Link to comment https://www.insanelymac.com/forum/topic/58547-no-display-black-screen/#findComment-418052 Share on other sites More sharing options...
crude7435 Posted July 31, 2007 Author Share Posted July 31, 2007 Alright, I was able to get the boot prompt to come up. I followed the instructions up to rm -rf nvdaresman.kext. That did not work, so I went on further to delete the other 5 kext file. That still does not work. The screen freezes up on the gray Apple screen and then eventually the message comes up that instructs me to hold down the power button until the system turns off. Do you have any other advice that I might be able to use that could get this running? Thanks!

crude7435 Posted July 31, 2007 Author Share Posted July 31, 2007 When I start in the -v mode, there are two messages that relate to two of the .kext files I deleted. kextd[25]: cannot resolve dependencies for kernel extension /System/Library/Extensions/NVDANV40Hal.kext kextd[25]: cannot resolve dependencies for kernel extension /System/Library/Extensions/Geforce.kext Other than that, I cannot see any other error messages. The last line says mentions "Login Window Application Started" so I guess that's an alright sign.

boinkytwo Posted August 1, 2007 Share Posted August 1, 2007 how did you remove the nvdaresman.kext? did you enter the command like this one below: rm -rf /system/library/extensions/nvdaresman.kext and furthermore, you can also do it like this cd /system/library/extensions/ ...press enter rm -rf nvdaresman.kext ...hit enter if still you cant boot up to the desktop after deleting all those mentioned kexts, insert your dvd and launch disk utiltiy, do a disk repair permission.

crude7435 Posted August 1, 2007 Author Share Posted August 1, 2007 Alright I did the 'Disk Repair Permissions' in the Disk Utility. The gray apple screen comes up for just a few seconds, and then a prompt comes up that says: localhost:/ root# Is that supposed to happen?

crude7435 Posted August 1, 2007 Author Share Posted August 1, 2007 Well I went back and messed around, and now it the gray Apple screen loads up, and the pinwheel continues to turn forever. But it doesn't freeze up, just turns forever. Thanks for the help boinkytwo! Anyone else have any ideas? Thanks in advance!

boinkytwo Posted August 2, 2007 Share Posted August 2, 2007 I forgot to mention, if you have sata drives, make sure you have installed the patch during install. as well as for ICH8R/ICH9R patch if you have those.
