Crabhunter Posted February 12, 2013 Share Posted February 12, 2013 I'm trying to get sound working on a new laptop at the moment and have just installed the VoodooHDA kext. This is causing a KP and horrendous sound at boot up. I'm now unable to boot even using -x or booting ML from the installer. I'm trying to delete it from the command prompt of the installer like this rm /Volumes/MLion/System/Library/Extensions/VoodooHDA.kext It's telling me that is a directory can anyone tell me how to do this.

TH3L4UGH1NGM4N Posted February 12, 2013 Share Posted February 12, 2013 Care to share after removing the voodooHDA why your system still didn't boot?

Crabhunter Posted February 12, 2013 Author Share Posted February 12, 2013 I havent got a clue, system was booting until I installed VoodooHDA then wouldn't boot with it, deleted it but it still wouldn't boot but at least it didn't make a screaming noise like it did with the kext. re-installing as we speak but this time to a small partition that I'm going to restore to the the large partition so if (when) I screw it up again it won't take so long to get back again.

Gringo Vermelho Posted February 12, 2013 Share Posted February 12, 2013 You have to boot with -f or UseKernelCache=n after deleting a kernel extension from single user mode, otherwise it will load from the cache anyway on next reboot.

WaldMeister Posted February 12, 2013 Share Posted February 12, 2013 for remove with terminal try this command: rm /Volumes/disc0s3-(THIS IS YOUR ML DISK)/System/Library/Extensions/VoodooHDA.kext From terminal you should use: rm -rf /System/Library/Extensions/VoodooHDA.kext The command you have provided will give back an error, stating it is a directory, so you need to use the -r or -rf flag, and only work if OS X is installed on disk0s3. 1 Link to comment https://www.insanelymac.com/forum/topic/286329-removing-a-kext-from-terminal/#findComment-1888332 Share on other sites More sharing options...
