So, I did something kind of stupid and started playing around with this file without creating a backup. Long story short, I ended up deleting the file: /System/Library/LaunchDaemons/com.apple.WindowServer.plist Can someone walk me through the repair process? I have a plastic Macbook. I also have at my disposal: An iBook running Tiger (it doesn't have a copy of the file ) The install DVD (I don't really want to reinstall OS X for one file) A firewire cable This information: "Default /System/Library/LaunchDaemons/com.apple.WindowServer.plist" I don't really know what I'm doing, which is obvious considering I'm begging on this forum. Help me out, if you'd be so kind.
