urgonah8me Posted January 24, 2008 Share Posted January 24, 2008 I am extremely please i managed to get leopard working almost perfectly on my laptop with an external HDD only problem is... (something i had the last time i installed it) is when i click shut down... the screen will turn off as normal.. but the laptop still remains on.. which is quite dangerous.. the only way to have a full shut down is to hold the power button for 5 seconds...which i could forget to do one time and then my laptop will overheat and die.. so how can i solve this problem? A while ago... i asked and iv looked in the forums and was told to download this file "AppleACPIPlatform" but i have no idea what you do with it can anyone help me out?

mtotho Posted January 24, 2008 Share Posted January 24, 2008 Join the club. Everybody has this problem and most of the time there is not a fix for a specific setup.. but if someone gave you a an appleacpiplatform.kext then you should replace your old kext. You go to System/Library/extensions and then drag it in. Then you have to go back into the /System/Library folder and delete the 2 files, one with the extensions'.kextcache' the other is like 'mkext' or something. restart and see if u can shutdown. If it doesnt work, i wouldnt be surpised. Just be happy everything works fine other than that.. OS x just has some trouble communicating with the bios to shut down.
