THIS IS MY STEP BY STEP situation with my updates:
I go to the Apple Icon and selected Software Update and it reads I have 2 items:
MacBook EFI Firmware Update 1.2
MacBook SMC Firmware Update 1.4
I select Install and then it state Installs completed successfully.
BUT THEN I recieve and new icon and this message below:
_________________________________________________________
To update the SMC firmware on your MacBook:
Your computer's power cord must be connected and plugged into a working power source, or your battery must be at least 25% charged.
For more information see 'http://support.apple.com/kb/TS3499'.
1. Quit all other open applications.
2. Click Restart in the MacBook SMC Firmware Update window and wait for your computer to restart.
The SMC firmware update starts automatically. A status bar indicates the progress of the update. During the update your computer fans will run at full speed, but will return to normal once the update completes.
Important: Do not interrupt the update.
Your computer restarts automatically when the update is completed and opens the MacBook SMC Firmware Update.
3. Click OK. The SMC firmware is now up-to-date.
If these instructions appear on your screen again, the SMC firmware update was not successful. Repeat steps 2 and 3.

I follow the instructions and then I get this: (could get my image to attach but here's what it said)
the first error message heading of:
MacBook SMC Firmware Update 1.4
Your firmware could not be updated, the hard drive partition scheme may not be supported. You must be booted from a GUID partition or RAID scheme.
see http://support.apple.com/kb/HT2434 for more information (internal error 28:3)
THEN ANOTHER ONE POPS UP saying:
Your Hard Drive partition scheme is not supported, you must be booted from a GUID partition scheme.
see http://docs.info.apple.com/article.html? artnum=303609 for more information

I went to those URL and tried to understand what it was telling me but I did not understand. I can't figure, by reading thru forums, etc, if I need to do this or not and what exactly it is.
So back to just pushing a simplet update has thrown all this unknown info. my way and I have no clue what to do.
Thank you. Hope this is more clear.
