software update problem

Please help! ><
I don't know why my mac is weird about update ==a
I update my mac for EFI Firmware 2.0 but when I finished it with booting,
nothing change. when I click 'check for update', the option to update
EFI Firmware keep appear.

I have the same problem for my word for mac 2011.
even if I installed the update and it said successful, nothing is change
in "about word last update" My mac version is 10.6.7.

Please help me how to resolve this! I googling this but find nothing
Thanks

I tried 2 ways.
first way: I just check software update and it says
"software update are available for your computer. do you want to download and install them?" if I click show details, I can find "EFI Firmware 2.0"
so I click continue > Install update and it downloading 1 item. After finish downloading, my mac tells me to restart the computer if I want to install the update (EFI Firmware) then I click ok. after the update finished, I check for update once again it still says that I need to update the Firmware T___T

2nd way:
I download the software from mac website and install it. but I find the same result as 1st way.

the same problem occurs on my word for mac 2011 too...
I never reinstall my OS and I've been using my computer just 6 month until now~

 

@Satori: Yes I got it. and it processed 'till finish...

 

@r0k: I just think if I call apple centre, things going to be harder.
I never call apple centre before but if I call, they'll give a resolve way through phone
or it is me who must bring my apple to them? *sorry am newbie

@bbazzahh: I never repaired before..T^T

 

I'm not pressing and holding the button because after updating, the mac restart
by itself and there was a long beep. Regarding step 6..there wasn't a progress bar under the logo because the gray screen just appear very slightly..
is it mean that my mac can't updating?
