ernando Posted June 20, 2006 Share Posted June 20, 2006 Hi all, I read several postings about deleting /System/Library/Extensions/AppleTPMACPI.kext and /System/Library/Extensions/AppleHWSensor.kext to speed up booting process. What actually are these files ? Is it safe to delete it ? I'm on JaS 10.4.6, cannot find AppleTPMACPI.kext but there is AppleHWSensor.kext. Thanks a lot Link to comment https://www.insanelymac.com/forum/topic/20099-appletpmacpikext-applehwsensorkext/ Share on other sites More sharing options...
boo50 Posted June 20, 2006 Share Posted June 20, 2006 yes it's save AppleTPMACPI.kext answer for TPM chip and this kext was deleted during install. AppleHWSensor.kext you can delete too without dangerous - it will decrease boot time.

ernando Posted June 21, 2006 Author Share Posted June 21, 2006 Using the instructions here : hxxp://forum.osx86project.org/index.php?showtopic=15993&st=0&p=122755entry122755, end up with kernel panic, but the strange thing is I could enter -x mode (Thanks GOD!!) and just remove both /System/Library/Extensions.kextcache and /System/Library/Extensions.mkext, after that restart, and should login without a problem. So I summarize it here : 1. delete /System/Library/Extensions/AppleHWSensor.kext 2. just delete both /System/Library/Extensions.kextcache and Extensions.mkext 3. restart Link to comment https://www.insanelymac.com/forum/topic/20099-appletpmacpikext-applehwsensorkext/#findComment-132854 Share on other sites More sharing options...
boo50 Posted June 21, 2006 Share Posted June 21, 2006 yes sure. after any changings of kexts you need to delete Extensions.kextcache and Extensions.mkext also i recommend to repair permissions in termanal (repair in disk utility not worked for me some times) Link to comment https://www.insanelymac.com/forum/topic/20099-appletpmacpikext-applehwsensorkext/#findComment-132885 Share on other sites More sharing options...
