HackedMac Posted October 24, 2010 Share Posted October 24, 2010 Hi All, Could kick myself. In brief, a working 10.5.1 install on an Acer Aspire 5610 working great for several years. While trying to create a new SL disk I discovered that I could boot my working Leopard 10.5.1 install as an external USB drive. Brilliant...I thought. Why not just carry that and boot to it from my work DELL laptop then I wouldn't need to lug two computers on the road. It didn't boot from the Dell. No big deal I thought...I'll just put it back in the Acer and go back to the way things were. MY BAD!!!! Upon putting the drive back in the Acer and powering up...it now no longer will boot past the Apple grey screen. When it goes to the blue screen ... the screen just flickers every so many seconds. It must have messed up my video kexts or something like that. Anybody got any ideas on how to fix??? I vaguely remember that there is a way to delete the kext cache and make it rebuild again. But I can't remember. Would appreciate any help. I have about three years of data and all my iTunes on that drive and I miss my Hack!!!!! Link to comment Share on other sites More sharing options...
aylamrin Posted October 24, 2010 Share Posted October 24, 2010 Try booting single user, safe mode .... Link to comment Share on other sites More sharing options...
HackedMac Posted October 25, 2010 Author Share Posted October 25, 2010 Try booting single user, safe mode .... If by that you mean booting with -x at the prompt, I tried that. Just ultimately get the the blue screen with the occasional flickers. Any other suggestions? I looked at the various boot prompts by entering ? and even tried setting a default screen resolution as mentioned in the guidance. No joy.

HackedMac Posted October 27, 2010 Author Share Posted October 27, 2010 just delete the /System/Library/Extensions.mkext Thanks for your reply. I booted with an Ubuntu 10.10 Live CD so that I would have a working platform. I can see the drive as well as follow the path to the file to be deleted. Unfortunately I cannot delete the file because it says I am not the owner. I think I remember having to login as Sudo (something???) to change permissions. Not sure if I will be able to do that since it didn't boot from Mac OSX and I can't remember the exact commands. But I am sure that your solution will fix the issue once I can delete and regenerate the extensions. If you could kindly give me a steer on the directions/commands it would be MOST appreciated! Vielen Dank! Link to comment Share on other sites More sharing options...
