想要反安装 Mac OS X 吗？有人提供这一个Apple Script！不过在使用之前一定要备份好重要文件
tell application "Finder"
activate
try
set this_version to the version as string
if this_version does not start with "9" or
this_version is not greater than or equal to "9.1" then
error "This script requires a Mac OS 9.x system greater than 9.0.4."
display dialog "This script will move Mac OS X items from the startup disk to the trash." with icon 2
display dialog "Should this script delete the Users folder?" buttons {"Cancel", "Yes", "No"} default button 3
set the users_flag to the button returned of the result
repeat with i from 1 to the count of the root_items
set this_item to item i of the root_items
if this_item is not "Users" or
the users_flag is "Yes" then
if exists (item this_item of the startup disk) then
delete item this_item of the startup disk
end if
end if
end repeat
repeat with i from 1 to the count of the systemfolder_items   
set this_item to item i of the systemfolder_items
if exists (item this_item of the system folder) then
delete item this_item of the system folder
end if
end repeat
beep
display dialog "The Mac OS X items have been placed in the Trash."
on error error_message number error_number
