[OSX-Users] Lion 10.7.3 update --- Beware!

[Jules]

Do *not* upgrade to Lion 10.7.3 by using "Software Update". You will 
wind up with a broken mess in which all the buttons have the word "CUI" 
written all over them, and no applications will work.

However, you can upgrade to Lion 10.7.3 perfectly safely by downloading 
and installing the "Combo Update" package from here:
     http://support.apple.com/kb/DL1484

*If* you have already broken your system, here's briefly how to get out 
of the mess:
1. Find another Mac (laptops are easier for this)
2. Download the Combo update from the link above on to the working Mac.
3. Boot the broken Mac into Target Disk Mode (hold down T while you 
switch it on, and keep it pressed until the big grey Firewire icon 
appears on the screen).
4. Connect the 2 Macs together with a Firewire cable.
5. The broken Mac's hard disk will appear as a disk (orange icon) on the 
working Mac.
6. Run the Combo update on the working Mac, but remember to "Change 
install location" to the disk that is the broken Mac.
7. Sit back and wait a few minutes.
8. When it's all finished, Eject the broken Mac from the working Mac, 
unplug the Firewire cable and power-cycle the broken Mac.

You should now have 2 working Macs!
