About Thunderbolt Software Update 1.2.1

Adds support for the Apple Thunderbolt to Gigabit Ethernet Adapter.

The update is a replacement for Thunderbolt Software Update 1.2, which was released last week but was pulled by Apple after users reported boot failures upon installing the update. Apple has posted a support article addressing the issue with instructions on how to resolve the boot problems.

MBA 13 2012 says this machine doesn't support the update or something to that extent.

Installed without a problem MBA 2011 11''.

Have yet to try the adapter back at home.

Not after last time!

I just checked on my mid-2011 iMac, and I don't have any updates. Although even if I did, after getting a kernel panic on my mid-2011 iMac for installing the last update similar to this, I don't think I'll be installing this one. Plus, I don't even need it on an iMac since an Ethernet port is present. Thanks, but no thanks, Apple!

The last time I update Thunderbolt make my Macbook Pro had to restore 3 times. In the next day, Apple pull out the update of Thunderbolt from their page. My Macbook Pro is middle of 2011.

Not allowing me to install on retina MBP. I just picked this adapter up today. Works great!

Has anyone tested the adapter when booting into windows using boot camp?

slrandall · Jun 18, 2012

Any idea when the TB to FW adapter is coming? That one's more important to me than the TB to GE one.

Yeah I agree. I don't like accessing my hard drives via USB 2.0.

My system doesn't show it in Software Update. I have a MBA 2011 and I have already got TB update 1.2 installed with a Thunderbolt GB Ethernet Adaptor currently working flawlessly.

Its not showing in my MBP 2010 13".

Same thing here with MBP. It seems we who had better luck with the original release don't need this one.

Didn't someone just release a port replicator that does USB and FW?

I was hoping for a TB to USB 3 adapter.

Same here.

More updates already than available devices.

But it's great they take care of maintaining TB.

LeGacY X · Jun 19, 2012

So is this simply a substitute for the previous thunderbolt update for the same purpose?

Yeap! It most likely just fixes the kext problem of the previous update that caused kernel panics on some systems.

What about a TB to phone coupler?

Yes but it includes the ability to use your computer after the update

My iMac hasn't been sleeping well the past week or so. Software update installed the first TB update but not this one. I downloaded it and now my imac's sleeping peacefully.

MBP's didn't get TB until it was released in early 2011
