MacBook Pro :: Why Does Thunderbolt NOT Recognize USB Keyboard
Aug 28, 2014
Once I disconnect the Macbook Pro from the thunderbolt and re attache it no longer recognizes the USB keyboard (all Apple products). I restart and switch USB cable around and sometimes it works but not consistently. Considering how much money is invested in your products you would expect them to work together.
Info:
MacBook Pro with Retina display, OS X Mavericks (10.9.4)
When I turn my macbook Air on, the screen is on and ready so I can enter my password but the mouse does not move. I can not use the keyboard at all and then I get a message saying that it is trying to pair my keyboard and it stays like that for ever.
When my laptop stopped recognizing my external keyboard and mouse I searched the discussions and found an answer that has worked, but only temporarily. It was to do a PRAM reset 3 times and when I do this the keyboard and mouse work fine. But when I disconnect the mouse and keyboard and then later reconnect it will not recognize them. I have repeated the PRAM reset 3 times each time this has happened (4 times) and they work fine but then there is always a problem when I disconnect and reconnect.Â
I've started installing XP onto my iMac, and it's at the screen where it asks what partition it should be installed on. In order to select a partition, I'm supposed to use the arrow keys on my keyboard, but my keyboard doesn't seem to be recognized by the installer, as well as other keyboards I've tried. So now I can't install windows. How can I get it to work?
I just blew out my old tiny keyboard that came with my iMac. I went out today and bought a new full sized keyboard from Best Buy with the alphanumeric keys. I followed the instructions which read:  Setting up your keyboardPlug the USB cable from your keyboard into an available USB port on your MacChoose Apple>Software Update from the menu bar and follow the onscreen instructions.When installation is complete and you've restarted you Mac, use Software Update again to make sure all of the available updates are installed.Â
I followed these instructions, and the best that I got told is that my iTunes was out of date, which I updated. My keynboard is working (obviously, I was able to post this), but it isn't recognizing the new placement of the volume buttons and such. Â
Have a iMac G5 with built in BT. I used it downstairs yesterday and took it back to the spare room where it usually is used. Fired it up today and I find that the BT mouse is fine BUT it ignores the keyboard. I tried; Replacing batteries. Checked that the suspect keyboard worked on my mac mini (it did). Tried my other BT keyboard on the iMac same problem. So, why does it recognise the mouse but not the keyboard? I do not have a USB Keyboard, so now I cannot Log in to fix it! I am guessing that the pairing has gone BUT surely it would simply see the keyboard as a new one and start setting it up. Something is stopping keyboards working with BT, very strange - could a loose BT module cause this? Or will I have to buy a USB Keyboard now to use my iMac?
I am trying to setup a simple, memorable keyboard shortcut for switching between tabs (a useful feature that I wish Safari made easier). I wanted to do option+arrow key. So I sent to System Preferences>Keyboard>Keyboard Shortcuts and created the shortcut.
The new shortcut shows up in Safari when I drop down the Window menu, but the shortcut doesn't actually work. When I hit option+L or R arrow key, the window does not switch to the next or previous tab. I even went back to Keyboard Shorcuts in System Preferences and created another "All Applications" shortcut with the same command. It still doesn't work.

I have a Mac Mini 2006 with Core Duo 1.66Ghz and an 80GB HDD. I use this computer as a Media Centre PC (not really nesecarry information). The 80GB hard drive has died in this machine. I know this because I took the drive out, formatted it, reinstalled it in the mini and attempted to install snow leopard from a boot disk. It gets to about 60% and then throws an error - clearly the drive is about to die. Â
In my wisdom, I opened the Mini up and replaced the hard drive with a drive from an old (but dead) windows laptop. When I did so and rebooted, I connected a USB keyboard and held down the option key on boot to boot into startup screen (to select the the boot disk I had made). The SL boot disk on a USB key which is recognised when I boot it on another mac. The mini seems not to recognise the keyboard input when holding down the option key. The mac booted straight into Windows which was on the new drive. It booted into the windows "windows did not boot correctly last time, do you want to start up in startup mode?) screen. The keyboard inputs were also not recognized on this screen.Â
I thought that there may have been an error because windows was on the drive, so I scrubbed the drive and re-installed it as a completely blank drive in the Mini. Again attempted to get to the startup screen and again the same problem. Only this time I am getting a flashing folder with a question mark (meaning the mini cannot detect any bootable drive presumably). The USB stick is flashing, but to me the Mini cannot recognize the keyboard input from the connected keyboard. Could the USB ports have somehow been damaged? Also through this process, I have reset the P-RAM on the mini as well. Â
My apple keyboard is not recognized by my laptop anymore. I've tried resetting the PRAM and SMC to no avail. The keyboard is almost brand new so I doubt it's broken... how to troubleshoot this?Â
I am using Apple Remote Desktop to control a Mac OS X Snow Leopard system with a Mac OS X Snow Leopard system. On the computer being controlled, I launch Windows 7 through Parallels Desktop Mac version 6. Once the VM is launched, for some reason it doesn't seem to recognize the keyboard as it will not allow me to Ctrl-Alt-Delete. I can use Ctrl-Alt-Delete through the keyboard menu, but I cannot enter in my Windows password.
I have an adapter for this, but when connecting my MBA to a new TV via HDMI, the TV screen shows my 'Mission Control' with relevant windows open, but not the content of those windows, such as a video playing in Safari. When I select the Safari window, the TV just shows the grey background same as Mission Control default?
Copying 1.3 TB of data from one USB2 drive to another, using the port on the TB display and a port on the MBP it was going to take three days plus, moving the drives so both coming off the MBP the data copies in about 12 hours, about what you would expect, and what I experienced on my Mac Pro. I have not noticed this in the past but have only ever moved small amounts via USB. (maybe I also need to run a speed test on the TB RAID.) All software up to date?

Now I have a 2009 MBP and a gorgeous LED cinema 27" display. It's the model before thunderbolt, so only mini-display, charger and usb connector on it.Â
I'm considering buying a new MBP or a MBA but am wondering... can I connect my LED cinema to this Thunderbolt port without burning up my screen? Will it detect that it should only do mini-display? I'm kind of afraid to try. The screen is perfect and I'd rather not change it. (only have it for 1 year now).Â
Just bought a new MacBook Pro. Tried using Data Migration Assistant. It was wanting to transfer data using my wireless network with an estimated time to complete of 40 hours. Would I be able to accomplish this faster using Thunderbolt?
I recently purchased Thunderbold (TB) display and 17" Macbook Pro. My TB flickers quite often and disconnects. Then I have to power off TB and reconnect. All updates are current. Dont know what the issue will be. Is there any utility to check the condition of TB. I did not connect any peripherals to TB except the Macbnook Pro.
Can I use my 27" Cinema Display with a 2012 MBP with Thunderbolt? The 27" Cinema Display is less than a year old but with the DVI cable, USB, and charger.
