***本人只是搬运工，签名机lion 10.7.5有效,经测试10.8.x,10.9.x均有效

重启保存屏幕亮度值

原理:
在/Library/Scripts/创建backlight.sh
在/Library/LaunchDaemons/拷贝com.delta.nvram.set.plist

实施步骤:
下载附件,解压缩,在终端中执行

1. cd /Users/xx/Downloads/backlight1   注:xx为电脑用户名称
   
2. chmod u+x backlight_startup.sh
   
3. sudo ./backlight_startup.sh

复制代码

如果要复原，请执行

1. sudo backlight_startup.sh restore

附：
#backlight_startup.sh的内容如下：

1. #!/bin/bash
   
2. if [ "$USER" != 'root' ]; then
   
3.     echo 'You must run this script as root'
   
4.     echo -e "Try: \033[0;31;1msudo $0 $1\033[0m instead"
   
5.     exit 1
   
6. fi
   
7. if [ "$1" == 'restore' ]; then
   
8.     echo 'Deleting script file...'
   
9.     rm /Library/Scripts/backlight.sh
   
10.     rm /Library/LaunchDaemons/com.delta.nvram.set.plist
    
11.     echo 'Deleting login script...'
    
12.     defaults delete com.apple.loginwindow LogoutHook
    
13.     echo 'Done!'
    
14.     exit 1
    
15. fi
    
16. if [ "$1" != '' ]; then
    
17.     echo 'Unknown argument(s)'
    
18.     exit 1
    
19. fi
    
20. echo 'Creating script...'
    
21. bash -c "cat > /Library/Scripts/backlight.sh <<EOF
    
22. #!/bin/bash
    
23. # (c) Slice 2010
    
24. nvram -x -p >/Extra/nvram.plist
    
25. echo Hello! NVRAM is saved!
    
26. EOF
    
27. "
    
28. echo 'Grantng execution privilege...'
    
29. cp ./com.delta.nvram.set.plist /Library/LaunchDaemons/
    
30. chmod u+x /Library/Scripts/backlight.sh
    
31. chmod u+x /Library/LaunchDaemons/com.delta.nvram.set.plist
    
32. echo 'Creating login script...'
    
33. defaults write com.apple.loginwindow LogoutHook /Library/Scripts/backlight.sh
    
34. echo 'Done!'
    
35. echo -e "To retore the modify, try: \033[0;31;1msudo $0 restore\033[0m"
