Thunderbolt port No device connected

Just purchased a new tb harddrive and when I connect it to my Macbook Pro 17 (early 2011) it doesn't recognize it? I am running Mavericks. It doesn't show up in disc utillity and if you look in system profiler under thunderbolt it says No device connected, Firmware Version: 13.0-2.8 and Port Micro Firmware Version: 1.2.1
Tried SMC and PRAM reset but no change.
I have another Macbook Pro 13 (late 2012) running Lion and it connected directly without issues so I know the drive and the TB cable works great.
There are no updates in the Appstore app that shows up so I was wondering if there is any firmware update for the TB port I need to download separate?

Same here.
Did anyone try to downgrade to Mavericks?

2011 Macbook Pro 17" Thunderbolt port "No Device Connected"

Please help!
I have a 2011 (early) 17" Macbook Pro (8,3)
Core i7 - 2.2
Boot Rom: MBP81.0047.B27
SMC: 1.70f6
Running Yosemite 10.10
I recently purchased a Akitio Thunderdock.
***It does not mount and when I check the system report, the thunderbolt bus shows "No Device Connected."
I reset the PRAM numerous times.
Reset the SMC.
Everything is plugged in correctly, with a proper thunderbolt cable.
When I attach the thunderbolt cable to the MBP, the blue LED on the on the dock lights up. (meaning link connected)
But the thunder dock will not mount.
Thunderbolt specs:
Route String: 0
Link Status: 0x101
Firmware Version: 20080d.0
Status: No device connected
Port Micro Firmware Version: 1.2.1
Before I got the dock I used (and still do) use the thunderbolt port with a mini display adapter to connect a 2nd display.
(works fine for this function.)
Thank you for your help.
J.
***Before suggesting it's the dock/power/bad cable:
I tested the Thunderdock with my GF's Macbook Air (2013) it mounts fine and sees every port on the dock (USB3, eSATA, FW800).

Thunderbolt port not showing connected device

I'm trying to use my 2d iMac 27" as a second monitor. I have the two iMac's connected via thunderbolt ports systems do not show any devices connected to either port.
Also, CMD F2 function (Target Display Mode) is not working.
Has anyone else this problem?
Thanks

Thanks dastoelk & Russ,
That definitly sounds like the issue, but the only thing new on the drive since the last time I opened FCPX is some new P2 media that's buried in the "PROJECTS" folder and some NEFs from a school play I recently filmed, in the "Greater Tuna" folder. But I have other P2 media and NEFs on this drive that have been on it for a while. Also, forget to mention, runnig FCPX 10.0.9

Connect multiple devices to one Thunderbolt port with docking station

Hello everybody,
for a video editing setup I would like to use all devices connected until now directly to my iMac just with a Thunderbolt docking station on only one Thunderbolt port. What I do not understand is, whether bitrate will stay the same for each device or will be splitted? Has this to do with daisy chaining Thunderbolt devices?
So this will be the setup:
1 Thunderbolt cable from iMac to Thunderbolt docking station
devices connected to docking station:
one Blackmagic Intensity Shuttle Thunderbolt
one external USB 2.0 hard drive
one external USB 3.0 hard drive
external HDMI monitor
Ethernet connection
So the general question is, will all of these devices get only part of the bitrate that Thunderbolt provides or can each device, theoretically, get full Thunderbolt bitrate?
And are there different types of Thunderbolt cables (Thunderbolt 1 or 2) that I have to pay attention to?
Regards DonTimo

Also, if you use the Apple 27" Thunderbolt Display, it will have an additional Thunderbolt and Firewire ports on its back.

I have a MBPro mid 2013 with 1 Thunderbolt port. Just bought a Mac monitor and want to daisy chain a PC monitor to it. Use a Mini DVI to VGA adapter from MBP to PC monitor. How do I daisy chain the 2 monitors?

Hall Palm Desert,
if your Mac monitor has Thunderbolt ports, and the PC monitor is on the end of the daisy chain, then you might be able to do it by connecting your PC monitor’s VGA cable to a Mini DisplayPort-to-VGA adapter (e.g. Apple, NewerTech), connecting that cable’s Mini DisplayPort end to one of the Mac monitor’s Thunderbolt ports, and then connecting a Thunderbolt cable between the other port on the Mac monitor and your MacBook Pro.

Better solution than PARAM reset to keep Thunderbolt Port properly working.

I have a MBP 17" (late 2011),
To its Thunderbolt Port I have connected my Samsung T260 Display alternately with a KANEX 'Thunderbolt to eSATA/USB3.0' Adapter.
But this always needs a PARAM reset after having the Display intermediately connected, else the ANKER 7xUSB3.0 Hub connected to the KANEX Adapter wouldn't be recognized correctly.
Is there a better solution available for selective resetting the Thunderbolt Port, without restarting the system?
Many Thanks for support.

Update: I obtained a new replacement MiniDisplayPort-to-HDMI cable, and both displays are working fine now. However — and this is what's weird — the fix was not completely immediate! At first, all the resolution modes (including 1080p) began working again, but I was still seeing ghost images of moved or closed windows on the screen! After a day or so, those went away. What could possibly explain the temporary persistence of the ghost images even with a new cable?

HT202856 Can keyboard brightness controls be mapped for a 4K monitor on the Thunderbolt port?

I have a 4K monitor (ASUS PQ321Q) attached to my late-2013 MacPro.
The monitor-button controls for adjusting brightness are awkward, to put it kindly.
Keyboard brightness controls don't seem to work. Is it possible to map them to control the external 4K monitor's brightness?

Yes. Here's a quote from the attached article:
If your Mac has one or more Thunderbolt ports, you can connect up to two displays to those ports.

Hi - my 2011 Mac Pro no longer recognizes devices in the usb ports, I've been told it's the logic board. is there a way I can connect the iomega external hard drive to it through the firewire or thunderbolt ports?

Ok, fair enough. But since Job's death - Apple's control on leaks has been terrible. I got the new iPhone, and I like it - but it hasn't made nearly as big as an impression as previous ones. Because of the vast ammount of leaks. With the iPad mini leaks, it's 99% sure to come out next week.
Apple uses many manufacturers and it's massive also websites prefer to report on Apple whether true or false because it brings more hits.
Amd by "others" I meant other people on iPads - not other devices/manufacturers. It's possible to do so, I just want to know how. I honestly don't think we'll ever be in a Post-PC era until all tablets allow us to use USB in the way computers do.
No, USB is not the future, you missed the memo about cloud and wireless computing?

Firewire device looses connection when external screen is inserted into the thunderbolt port? HELP

HI
I am a recording studio engineer. Ive got a Firewire AD/DA Converter (Focusrite Saffire Pro 56) running from my Firewire port of my MacBook Pro, which is running OSX Mavericks. I've also got an external Screen I want to use as an extended display. I'm using a HDMI cable from the screen to a HDMI to Thunderbolt Converter which I then plug into my Thurderbolt Port.
As soon as I plug the screen in, the Firewire Port looses connection completely and I cant use or even choose the Saffire Pro 56 as audio driver. Another thing happens where the Thunderbolt port replaces the Saffire Pro 56 Driver with the screen as the audio output source.
Please help, there's nothing I can find to fix this.
Thanks Maurice

You don't mention which model you have, but this is from the M-Audio Firewire 410 Manual Troubleshooting section:
The FireWire 410 has been designed to give you high performance and professional quality audio. It has been tested under a wide range
of systems and operating conditions. In the real world, however, there is a nearly infinite number of possible operating scenarios, any of
which could affect your system’s performance. Much like owning an automobile, “your mileage may vary.” This section can not begin to
cover all possible issues you may encounter, however we want to give you some suggestions on common problems you may experience.
One thing to avoid is connecting too many devices. The FireWire bus is a dependable, high-speed, high-bandwidth protocol which is ideally
suited for digital audio. Nonetheless, it’s important to remember that audio and multimedia streaming places considerable demands on
your processor and the FireWire bus. Although it is theoretically possible to chain many multiple FireWire devices in series, doing so may
potentially degrade your audio performance.
I guess this degradation could also affect the Firewire HD. Maybe there is a simple fix, but it sounds like the M-Audio people have been down this road before.

Can I connect multiple devices to one thunderbolt port?

I have the need to connect an external monitor and a firewire cable to my Macbook Air, but with only one Thunderbolt port I am trying to determine if this is possible. Is there such an adapter that would take my single Thunderbolt port and 'split' it into two?

Also, if you use the Apple 27" Thunderbolt Display, it will have an additional Thunderbolt and Firewire ports on its back.

How to connect two DVI screens to Thunderbolt Display's Thunderbolt Port?

Hi everyone,
I have a new MBP and an external Thunderbolt Display. The Thunderbolt Display itself has a Thunderbolt port, and I was wondering if there is anyway to connect to DVI screens to that. My goal is to have the Thunderbolt Display and 2 x 24" Samsung DVI screens connected to my MBP.
Alternatively, has anyone had success using a third party device like the Matrox 2 go to drive multiple monitors from the usb port?
Thanks,
Dave.

You could try a TB>DVI adapter (here's one from Monoprice) but I don't know that it will work - I'm thinking that you could have at least one of your Samsung displays use it. You may also want to see if you can find a HDMI>DVI adapter for your second Samsung display - something like this?
I know that I've seen three monitor set-ups on YouTube - but I'm not sure what was connected to what. Easy enough to daisy-chain ATDs but it gets a bit tougher when utilizing HDMI ports, etc., and I'm not sure about the GPUs ability to drive all three displays.
Oops - sorry - strike that second paragraph - I thought that you were running a Retina display MBP...

One Thunderbolt port for two HDMI devices?

Hello
I was wondering, is there some sort of adapter that I can put in the thunderbolt port for my mac mini and connect two hdmi devices (monitors)?
HDMI 1
Mac Mini - 1 TB <
HDMI 2

Use the HDMI port for one monitor and a mini displayport to HDMI adopter on the other. That adopter plugs into the Thunderbolt port.
You want to set them up as extended displays.

I have a Macbook Pro 13.3 i5 w/ no hdmi port. How can I connect my Mac to TV to watch video, photo ? Is the Thunderbolt port a mini display port where I can use a mini display port to HDMI cable? If not, what are my options??

I have a Macbook pro 13.3 w/ i5 that has no hdmi port. I want to be able to connect the Mac to my TV set to watch Video, Photos and files from Mac to TV.
Is the Thunderbolt port similar to a display port or mini display port? Can I use thunderbolt port to connect thru a mini displayport to HDMI cable or converter?
Been trying to locate a USB to HDMI cable or converter (at a reasonable price) but all I found is a displayport or mini displayport to HDMI cable/converter.
What other options are available ?
Thanks a lot for your assistance.

Thunderbolt uses a Mini DisplayPort adapter to send video and audio to HDMI. Here's some on Amazon http://www.amazon.com/s/ref=nb_sb_ss_c_2_8?url=search-alias%3Dcomputers&field-ke ywords=mini+displayport+to+hdmi&sprefix=mini+dis%2Caps%2C249#/ref=nb_sb_noss?ur l =search-alias%3Dcomputers&field-keywords=mini+displayport+to+hdmi+with+audio&rh = n%3A172282%2Cn%3A!493964%2Cn%3A541966%2Ck%3Amini+displayport+to+hdmi+with+audio

How to connect iMAC thunderbolt port to a cable TV set top box?

I am moving to a house that will have combination TV-phone-Internet services delivered via cable (Optimum is the provider). I understand that with my new iMac which has a "thunderbolt" port that I can use the iMac as a tv monitor and DVR (recorder) and watch live TV or recorded TV. I think it is possible to record TV shows either on the iMac's hard drive or the Optimum DVR. Beyond that, I get confused because I do not understand the details of RCA cables, coaxial cables, HDMI connectors, etc. Apple does not provide support for set top boxes (I called Apple), and Optimum does not provide support for Macs (I called them too). Since Apple is the party advertising the capability of watching TV on a Mac, I would think the burden is more on them to explain how that works, and maybe they have done so on their web sites, but I cannot find it so far. I can understand that the cable company does not want to tell people how to bypass the need for their DVR equipment. Before I go out and hire a consultant for a few hundred dollars to explain it, I was hoping I might find online some tips on how to set up a system at home. No luck so far.
Am I correct in assuming that wireless connections are NOT an option because a TV signal has too much bandwidth to work wirelessly? (I do have a wireless router already.)
If so and if I am using wires to connect the iMac, am I correct to think I want to use the thunderbolt port for best results?
If so, what next? What exactly is the adapter or cable I need and how do I plug it into the set top box? There are several people in the household, and so I would want the flat screen TV monitor to work normally at times rather than only use the iMac. Does that require several set top boxes? I would think that this would be an issue for many people, and it seems to me that this forum would be an ideal place to get help. So far the people I have spoken with say "well it depends on what you want to do and what your equipment is and for that you have to go ask ___________[someone else]"

I do not understand what Apple TV is. I have TV already. When I look up "Apple TV" on the Apple website I see that is has been redesigned to be small in size but big in entertainment. Since I did not know what it was BEFORE it was redesigned, knowing that is has been redesigned does not help me understand it. Now it is smaller? So it was too big before? "Watch Netflix titles instantly." But I can do that with my mac and an internet connection now. So what is Apple TV that makes it a better or different way to watch Netflix movies? "Best of all, Apple TV is just $99" Sorry, but how is that the Best of All part? My Optimum Cable is charging me $30 a month for TV. But Apple TV's best part is it costs $99? Is that per month too? I also see that everything streams wirelessly to Apple TV, and all I need it so connect apple tv to my widescreen TV using an HDMI cable sold separately. Now I am really confused. I plug in a cable to get wireless streaming? If it is wireless, why does it need a cable? If there is a cable involved, how is it wireless? Color me clueless. I cannot find a straight forward description of what Apple TV is. And so I don't get how that is the answer to my question. Sorry for being so simple-minded. Thanks for the suggestion and I will go research further to learn what is an Apple TV.

I want to Connect my Mac Mini as a Slave to a Mac pro Server while at the same time using the Mac mini's thunderbolt ports peripherals ( ie monitor, Sound Card, Hard drives) Creating a poor man's new mac Pro. Can this be Done?

Well, I really would love the new unreleased mac pro however , I'm not sure of the expected cost , Everyone speculates from $3,000 to $8,000, in which I may have to wait a while to purchase.
To the point .... I want fully functional thunderbolt ports to be on the current mac pro's .... wonder if anyone had workarounds yet?... or could I chain the the current mac pro to a mac mini to make that happen?
