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.

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

I was hoping for a TB to USB 3 adapter.

Not needed on most Macs (non Retina)

I didn't get this through software update for my late 2011 MBP. Downloaded and installed it, but 1/2 way through installation, I thought "I have a built in 1GB ethernet port, so why am I installing this?" I can't imagine wanting to use 2 ethernet lines at the same time.

Thunderbolt to Esata would be great, but I don't want to pay the current $200 to $300. I bought an Esata drive from Other World Computing with an Esata adapter also from them to use with a 2008 MBP. About a year later they report that this adapter doesn't work with MBPs in the 15" range (couldn't figure out why my date kept corrupting)

Now I have a 3 TB drive that I can't hook up without spending 200 to 300.

Hopefully these will come down in price.

What about a TB to phone coupler?


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

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