davejones Posted June 6, 2008 Share Posted June 6, 2008 Hello all, Can you please help me out and answer the following questions for me: Is it ok to keep booting my Hackintosh with the "-s" command on the EFI v.80 boot menu? The reason I ask is because this is the only way I can get my sound card to work & stay after each reboot (otherwise it always disappears). What exactly does the "-s" do & are there any disadvantages or negative effects of always booting with it? Lastly, is there anyway to boot with it enabled permanently (without me having to press F8 & type "-s" at each boot up?) Cheers guys, davejones Link to comment Share on other sites More sharing options...
my_buck Posted June 6, 2008 Share Posted June 6, 2008 Hmm... You might try to edit your com.apple.Boot.plist sudo -s nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist add this: <key>Kernel Flags</key> <string>-s</string> Tips: http://wiki.osx86project.org/wiki/index.php/Tips_And_Tricks Link to comment Share on other sites More sharing options...
davejones Posted June 6, 2008 Author Share Posted June 6, 2008 Thanks my_buck, That works perfect, but do you know how I can bypass having to type exit everytime whilst trying to boot with the "-s" command?... Cheers, davejones Link to comment Share on other sites More sharing options...
my_buck Posted June 6, 2008 Share Posted June 6, 2008 bypass ..., I don't know, but you can only increase the timeout <key>Timeout</key> <string>10</string> sound problems, I think, it's better to clear all these sound-related kexts and install them again. You can take a look at onyx. It offers the ability to clear cache and more. http://www.titanium.free.fr/pgs/english.html Link to comment Share on other sites More sharing options...
Krazubu Posted June 6, 2008 Share Posted June 6, 2008 There's no reason for -s giving sound when normal boot doesn't. It's probably only a kexts cache problem. Remove /system/library/extensions.mkext and try to boot normally. Link to comment Share on other sites More sharing options...
davejones Posted June 7, 2008 Author Share Posted June 7, 2008 Thanks my_buck & Krazubu, @ my_buck I have tried you your suggestion, but even after clearing all the relevant caches via Onyx (1.9.5) the result is still the same. After a reboot, I lose all audio (including entries in System Profiler), unless I boot with the "-s" command (but I have to keep typing exit everytime after mention of a Firewire error that is defaulting to full speed)??? @ Krazubu I agree with what you say in theory, but, unfortunately in practice it still only works with the booting with the "-s" command. I even edited a a script to clear the relevant caches (see below): #!/bin/sh . /etc/rc.common sudo chown -R root:wheel /System/Library/Extensions/AppleHDA.kext sudo chmod -R 755 /System/Library/Extensions/AppleHDA.kext sudo touch /System/Library/Extensions sudo rm -R /System/Library/Extensions/Cache sudo rm -R /System/Library/Extensions.kextcache sudo rm -R /System/Library/Extensions.mkext sudo rm -R /System/Library/Caches/com.apple.kernelcaches echo "Done !" I even tried it with and without AppleHDA.kext at the end! Followed by a Disk Utility "Repair Disk Permissions", but the result is still the same everytime?... Any ideas... BTW I appreciate all your advise. Cheers guys, davejones Link to comment Share on other sites More sharing options...
