Updating hackintosh version
Well you should be able to do it with Admin login or if you have admin rights.
1. Open up the Terminal window
2. Run the following commmand
"sudo /Applications/TextEdit.app/Contents/MacOS/TextEdit /System/Library/CoreServices/SystemVersion.plist"
Now, in this file, replace the version no. 10.5.x or 10.6.x for 10.5.x e.g. 10.5.2 to 10.5.7 ( if you wish to install Xcode 3.x)
Save this file and exit. You're done.
Now, if you don't have the admin rights, dont worry. We've a solution for that as well. Restart the machine. On the startup prompt, press F8, enter -s, (single user mode), it will bring you to a command line with a prompt. Now, here you have the root permissions. Just type the following commands:
a. "/sbin/fsck -fy"
b. "/sbin/mount -uw /"
c. "vi /System/Library/CoreServices/SystemVersion.plist"
Now, press "I" or any alphabet to edit the file. Change the version no. that you desire e.g. 10.5.2 to 10.5.7 (whatever), press ESC key, press : key, type wq! and press Enter. You're done! Just restart the machine as you normally do. Voila! you've the updated version of MAC.
