thunderbolt firmware update not updating

I found your topic searching because I have the same problem. Yet, I'm trying to update it without a monitor plugged in. hmm.

 

same issue

won't update the Thunderbolt stuff

 

That is a common issue at our shop.

Simple question:

Are you updating connected to a power source?

If you are not, this is normal. MAC OS X is not going to update ANYTHING critical as (any) firmware if it is not connected to an external power source. Battery is not considered by MAC OS X as a reliable power supply, therefore it will prevent ANY failure during such a critical process (that must not be interrupted in any way) by not allowing it at all.

Therefore in that case you will experience the following:

- Update will download.
- Update will uncompress and install will start.
- After installing software it will reboot.
- A gray screen will appear, then the apple will show in darker gray.
- Then a status bar will show up, eventually by about 1 second (that is the time the EFI delays to know if it's magsafe is connected or not).
- Then the process will be interrupted by itself as a safety precaution in the moment it notices it is not connected.

So next time do it normally, but TAKE CARE you DO CONNECT your magsafe to your computer before you start the process, and it hopefully will go smooth as... (think in something really smooth he he)

Hope this helps someone.

Hi,

I've tried this a number of times with the Magsafe power plugged in. It still doesn't update, after a number of times. If I go back to Software Update, it still asks me to install the Thunderbolt Firmware, as if it hadn't updated.

So for me, it's not working even with power on.

Cheers,
Stu

 

I had the same problem.

Connecting to a power outlet solved it for me.

 

Let's me try it
