    Awesome!!!

    • Written by from RICHARDSON

    I'm very happy Apple goes the extra step to actually implement the standard; I'm extremely pleased with the 1394 implementation; for all those questioning the power handling of this adapter...the fuse on the 1394 power side is a 1.5A fuse..fully compliant with the standard; you can transport 10W+ continuously over this little thing (it'll work near 15W too :-) ), which is good enough for some serious medical applications, such as mine. Thanks Apple for squeezing essentially a PCI express card down to that size and still be compliant, and have very nice thermal performance as well. Also great job on the EMI shield design.

    Will not power external HD

    • Written by from CLARKSVILLE

    Forget trying to use this on a portable HD that doesn't have it's own power supply. It will not work. Does not provide enough power.

    underpowered

    • Written by from Portland

    This can provide only 7W to firewire devices. There are many, many devices that need more than this. You should absolutely check before buying to find out what your devices need in terms of power. Otherwise this is useless, as it is for me more than half the time.

    Works exactly as advertised

    • Written by from Commerce Township

    This is a Thunderbolt to FW800 adapter, as such it works exactly as advertised.

    There are a lot of editorial comments in the reviews but this works as advertised. It is reliable and offers good performance when used with FW800 drives

    Apple's losing their touch

    • Written by from North Canton

    I needed the FW 400 connector, didn't verify this one would work before ordering since there was only one option, and the adapter in the mail is only compatible with the FW 800 devices. I'm afraid that getting an adapter from 400 to 800 may cause compatibility/performance/driver issues which is the last thing I want to have to consider after a costly upgrade to thunderbolt. Working with Apple is feeling more like the PC world all the time. Good thing I have nothing else to do since I'm now on the hunt for a FW to FW adapter to go into Apple's Thunderbolt to FW adapter and hope that it works. Very disappointed.

    Only one FW capability but there's two FW options?

    • Written by from Powder Springs

    I can't help but feel cheated and robbed by Apple..... they had no problems over the years selling me FW 400 and FW 800 devices yet this adapter only works with one of them. I can't even connect my older Apple iSight without now going out to find someone who sells a FW to FW adapter to go into Apple's Thunderbolt to FW adapter. pretty stupid if you ask me. Why didn't you include an adapter within the adapter if you're going to require it anyways?

    Extremely disappointed

    • Written by from Houston

    This is for Firewire 800, the older G5 Firewire are not compatible and now I need another converter just to sync information and files from another mac. I have spent way too much money converting everything to Thunderbolt already and now I need a converter for the Firewire 400. I am disappointed in Apple Inc. and their Thunderbolt.

    Thunderbolt to firewire adapter for older camcorder Mini DV (Panasonic)

    • Written by from Norwalk

    Previously used firewire 400 on old mac. Bought a firewire 800 cable 9-4 pin and adapter.
    New firewire cable worked in my daughters Mac Book Pro 2011. Imported video---so I know that part works.
    I added the adapter for my retina Mac Book Pro 2012.. I does not recognize camcorder.
    Either its the adapter or the imovie 11. Next I will try a different import program and see if it recognizes camcorder. I have so many old tapes to transfer!

    works, but...

    • Written by from Stuttgart

    Works fine with digi 002 and focusrite saffire 24 audio interfaces.
    BUT (and thats why only 3 stars):

    Because thunderbolt only delivers 7w thru the FW adapter many bus powered FW-devices need an ac-adapter.

    Not all FW800 to FW400 adapters are working with the thunderbolt adapter. Some of my adapters let go power through the cable but the interfaces for example are not recognized. Sonnet FW800 to 400 is working fine with apples thunderbolt to fw

    No thunderbolt port next to the firewire?

    • Written by from New York

    It does what it's supposed to, but I don't understand why it doesn't have another thunderbolt port on the the firewire end, I can't connect two displays and still use firewire, unless I use the HDMI, but than I need another adapter. I thought one of the strong points of thunderbolt is the ability to daisy chain.

    Not working with (at least) RAID 0 FW800 drives

    • Written by from Washington

    I'm very disappointed with this cable. For whatever reason, my Late 2012 27" iMac will not recognize the self-powered FW800 externals that I have been working with for years. I'd love to know why.

    Slow and unreliable connection

    • Written by from Bellevue

    This has proven to be a poor substitute for my years-long trusted FW800 connection to my external, self-powered, hard drives especially my Drobo drive.

    I've been simplifying my setup for my brand new iMac 27" and have kept only the Drobo drive on FW800, through this adapter. My transfer rates have been cut in half to barely USB 2 speeds, and even more problematic the connection hangs several times a day, likely when the bus goes to sleep. I therefore have to reboot my Drobo several times a day, whereas it has been running flawlessly and without interruptions for three years now.
    Needless to say FW800 is no longer an option for me. And given the very high prices, Thunderbolt is not yet an realistic alternative for mass storage.

    Compatibility Issues

    • Written by from Peachtree City

    I had no problem using the adapter with external powered Firewire drives. Unfortunately, my bus powered portable Firewire drives (2 different bands) were not recognized and would not boot despite the drives appearing to be powered (LED & spinning disk). I verified the issue on two Macs, a late 2012 iMac and a Macbook Air. Bummer!

    Thunderbolt to FW 800 to FW 400 adapter does not support Hasselblad cameras

    • Written by from San Lorenzo

    Well dang... A brand new Macbook Pro Retina, new Photoshop, new Lightroom and I bought the 2 adapters recommended by Apple- Thunderbolt to Firewire 800, Firewire 800 to Firewire 400- to dump my 132 meg photographs onto my shiny new 16 GB Ram machine... Say What??
    NO GO!!! Oweeee. I called apple tech support, the guy runs a few PRAM reset programs and then proceeds to tell me to bring my new computer into an Apple store, the nearest one being about 7 hours round trip.
    Let me explain- the Thunderbolt to Firewire 800 adapter works great on my Lacie hard drives. The Firewire 800 to Firewire 400 works great on my older MacBook Pro Firewire 800 port to run the same hard drives. So I guess the adapters are fine.
    So WHY Can't the combination work together to run a powered Firewire 400 drive???
    I am irked as the Apple tech/sales guy who helped me put this computer together told me Apple had the solution when clearly it hasn't been sorted out yet.
    As I said back up there- DANG!!

    Firewire drives way slower through adapter

    • Written by from Austin

    It works fine, but if you are currently using a Firewire drive with your non-retina macbook, be aware that using the adapter (required for retina macbook pro) makes the drive much slower, at least for large writes.

    I copied a 32GB file to my WD MyPassport Studio external firewire drive at it took ~30min when copied from a Macbook Retina Pro 15" SSD (via adapter), compared to ~10min when copied from a early-2011 Macbook Pro 15" SSD (which has a much slower internal drive).

    No Firewire 400 if bus power is needed.

    • Written by from Madison

    I have an external FireWire 400 drive that does not require a power supply when connected to either a FireWire 400 or 800 port (with 400 to 800 cable). When I try this Thunderbolt to FireWire adapter with a FireWire 800 to 400 cable, it does not work. Apple should either put this in the description, fix the issue or sell a Thunderbolt to FireWire 400 adapter.

    Only works in one way...

    • Written by from Carlsbad

    I purchased this cable to plug my 1TB Buffalo MiniStation Thunderbolt portable drive, into the Firewire 800 port on my older 17" MacBook Pro (which has no Thunderbolt ports). It didn't work. I called Buffalo tech support, who told me the drive will not work this way. It has to be plugged directly into a Thunderbolt Port.

    So I give this product 2 stars mainly for the product description, which clearly explains that the cable plus into a Thunderbolt port to give you an FireWire 800 port... but does not explain that the cable WILL NOT connect a Thunderbolt peripheral to a Firewire 800 port. I think it was a logical assumption that it would...
