Macbook Pro loses bluetooth functionality when plugged into thunderbolt display

This a fix that I think should be out there, because I searched and searched for months, then just found the solution myself. Want to make sure someone else doesn't have to deal with what I've been going through...
I've been dealing with bluetooth mouse, keyboard and trackpad dropping off unexpectedly on my MacbookPro Retina 15" ever since Yosemite. No bluetooth at all, even though it's showing that it is functioning normally. Usually this happened whenever I plugged in my thunderbolt monitor. It's maddening when you pop out for a meeting with your laptop, then get back to your desk ready to jam - then you're just frustrated clicking hopelessly on your mouse. Sometimes bluetooth comes backs, sometimes it doesn't until I restart. Turning bluetooth on or off had no affect. I came up with the weirdest fix yesterday, and so far it is working...
1) turn your wifi off
2) start clicking/moving your mouse, trackpad or keyboard until it gives you the "connected" notification on screen
3) turn your wifi back on
Weird! I made the connection when seeing people griping about wifi being hampered when bluetooth was on in Yosemite, and thought it might go both ways. Hope this helps.

WIFI AND BLUETOOTH FINALLY SOLVED, NO REALLY - YOSEMITE 10.10

Toshiba backup drive not recognized when plugged into thunderbolt display.

My Toshiba backup drive does not mount to my MacBookPro when plugged into my Thunderbolt Display. It works beautifully when plugged directly into my MBP, and other USB devices work beautifully when plugged into the same USB ports on the Thunderbolt Display.
All my equipment is pretty new. The Toshiba is currenlty configured to be my Time Machine back up drive.
Laptop: 15" Macbook Pro, 2.8 GHz Intel Core i7, 16 GB 100 MHz DDR3, Mac OS 10.8.5
Backup Drive: Toshiba 500GB Canvio® Basics USB 3.0 Portable Hard Drive
Apple Thunderbolt Display: 2560 x 1440, NVIDIA GeForce GT 650M 1024 MB graphics
When I plug the backup drive into the TB Display, usually nothing happens. The blue light on the drive doesn't come on, and it doesn't mount to the desktop. If I wiggle the USB back there, sometimes the blue light will come on, and sometimes it will mount for a minute then go away. This is true for all 3 USB ports. I have not had problems with any other USB devices, but the only other ones I've plugged into the Thunderbolt are my keyboard, bluetooth headset charger, and other items that probably use less power than the backup drive.

But the cable works when plugged into my laptop. Plus, the cable connection is pretty specific to the device; I'm not sure if you can buy another one seperately.

MacBook Pro fans running when plugged into Thunderbolt displays

I just got a sweet setup at work - a new MacBook Pro and 2 Thunderbolt displays. However, immediately upon setup I noticed the fans on the Mac Book operating constantly, even when I was just surfing the net or working in one Microsoft program.
I just spent a few hours working on the laptop - not plugged in to the Thunderbolt displays - and the fans did not go on at all. Within minutes of plugging it in to the displays, the fans started up again. So I think it may have something to do with the Mac Book being plugged into the Thunderbolt displays.
Can anyone help?
Mac Book Pro, Version 10.7.2, 2.4 GHz Intel Core i7, 8 GB 1333 MHz DDR3

Hello,
I'm so sorry for the slow response! I ended up calling Apple because I was still mystified and no one was responding here.
The nice gentleman at Apple told me the following. The MacBook Pro can handle two Thunderbolts max. If the CPU is constantly running hot, then it could be an issue in the long term.
We went through the software update process for the Thunderbolt displays again, and it turns out that the software was NOT updating!!! It's not the usual "click install and the computer takes care of it all" sort of update - unfortunately I don't remember exactly what we did, but you have to go to the Applications folder and actually install something.
You'll know if you haven't followed these steps if, when you go back to check for updates, the Thunderbolt display update keeps popping up.
Since installing that firmware update, I have been using my MacBook with only one display. In the next week, I will probably plug it in to the second display and see if there are fan issues. If so, then Apple told me to call them back and see about further troubleshooting.
I hope this was somewhat helpful. If you are still unclear, I'd say call Apple! They were really helpful! Good luck!

Wireless issues when plugging into Mac display

I have noticed that no matter where I am in the house, my Macbook Pro works with my Airport just fine. But when I plug the laptop into a 24" display, my wireless signal does one of two things: it drops a connection, going from full strength to nothing and back again, bouncing back and forth in a slow rhythm, or it will give me a huge drop in strength. Anybody have any idea why this is? Your help is greatly appreciated.

I also have the same issue, specifically similar to that of DimBimbleby, since I am using my MacBook (2008) connected to one of the Apple 24" LED Displays via an Altona converter in the mini-DVI port. The laptop works excellently when not plugged into the display, as do my DVD player (streaming Netflix) and my AppleTV (will never figure out why I bought that) - as soon as the monitor is plugged in, the internet is either extremely sluggish or does not work at all. It took me a bit to figure out that it was only after the display is connected (moved both things all around the house of course). Does anyone at all have ANY idea how to fix it or improve it?? It's really frustrating and I certainly did not pay all that $$ for the display for it not to work with internet. I recently sold an older style 20" ACD Monitor which never had a single issue working with the internet. I have a Linksys Wireless-N router which is not the greatest ever but works well with everything else. Please help!!!!!

Macbook Pro 13" Screen went Black - Can only see when plugged into another display! HELP!

My MacBook Pro's screen went black last night and now when it turns on it stays black. I plugged it into my tv through the mini display port and I can see everything fine on the tv but the screen on my laptop is black. Everything else seems to be working fine. Any advice that doesn't involve taking to Genius Bar??? Already tried booting in safe mode, resetting the PRAM and NVRAM. Need to fix this ASAP. Thanks!!

Please make a Genius Appointment and take it in for service.

How to get my MacBook to open new space when plugged into tv via HDMI?

Alright. All of my roommates & myself have MacBook Pros. When they plug them into the tv via HDMI, the computer opens a new separate empty space on the tv where you can drag windows from your laptop to the tv screen so you can still use the computer at the same time as watching a movie. However, when I plug mine in, it just shows what is on my computer screen & I really want to know how to change it.
Pleaseee someone help me!

Macbook Pro Retina - Weird sound when plug in adaptor

Hi,
I have had my Macbook Pro Retina 15inch now for about a year and a half and suddenly it's making a sound whenever I plug it in. It's like the sound of a hard drive, but it's in sync with when I scroll up and down. There's no sound whenever it's unplugged, it's very strange. Any ideas, could it be a faulty adaptor?
Thanks
Lewis

It is better to take the computer to the Apple store and have it checked out.
If this does not help, contact Apple.

Why does my iPhone 4 lose 3G signal when plugged into the TV with the AV Adapter?

When I plug in my iPhone 4 (Verizon) or my husband's iPhone 4 (AT&T) to watch Netflix, Netflix stalls and the 3G signal disappears. I have tried connecting the adapter both before and after entering the application. I believe the digital AV adapter and HDMI cable are fine, because I have no problem seeing output from my iPad 2.
When I plug in the adapter, the 3G signal will disappear shortly thereafter. The red Netflix screen will appear on the TV, but 9 times out of 10 it will go no further. One time it stayed on the red screen, but I heard the audio from the movie. Another time it showed the movie for 10 seconds, then stopped. When I unplug my iPhone, it will take a while to regain the 3G signal.

I had the same issue in my 2012 Nissan Altima. It was a function in my car's stero settings. I had to go to the car's iPhone/iPod settings when the iPhone was plugged into the USB. My settings come up automatically when I plug in and I can scroll through the commands to "Shuffle" songs. Hope this helps.

MacBook Pro Mid 2012 freezes when plugged in

Hi. My Mid 2012 MBP which runs on Yosemite 10.10.2 keeps freezing even when just browsing on Chrome so I uninstalled Chrome and used Safari. I was still having problems after switching browsers so I restored my device to its factory settings but the restore did not solve my problem. All this time my device was plugged in so I unplugged it and tried to browse. It did not freeze or crash. I read the forums and found out about the SMC reset and a NVRAM reset but my device is still freezing when plugged in. I am typing this while my MBP is unplugged. Please help.

Reset the SMC again:

Experiencing instability when plugged into multiple displays

I upgraded to Yosemite when it was released. My desk has two apple 27" monitors connected to my Macbook Pro Retina. I noticed immediately that there was stability issues when I plugged my mac into a projector (over the HDMI port). Generally the issue has been of the UI hanging (beach ball) - the top menu and the doc not responding to mouse input.
But recently the system has been actually crashing when I plug into the monitors at my desk.
Hopefully these things are fixed soon.

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.
Feedback
Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.
Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.
Isolating an issue by using another user account
Try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear and again when you log in. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don’t do them all at once.

I have erased programs, music and everything left in my computer. Im running normally on 27% of the RAM memory (8gb) and have a capacity of 500+ GB left in the HDD. Please Advise...

Hi there Chiefinho,
You may find the troubleshooting steps toward the bottom of the article below helpful. Please keep in mind, diagnosing a recurring kernel panic can be difficult. If you would like to avoid this process, or do not know how to perform any of the following steps, consider bringing the Mac to a Genius at an Apple Store or an Apple Authorized Service Provider for assistance. Be sure to ask that, if the drive needs reformatting or replacing, they contact you about escalating your case to a special data recovery service. If you plan to visit an Apple Retail store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).

Can I hook up an early 2011 macbook pro to a new iMac AND another thunderbolt display?

I want to get a new iMac, and I have an early 2011 macbook pro. Can I use a two-way thunderbolt cable to hook these two up? If so, will I still be able to use full functionality on both as I move windows to and from one of them? (Like, I use my macbook track pad to move a safari window over to my iMac, and then I can either use my iMac mouse or my macbook's trackpad to do things with that safari window.
ALSO, is it possible to hook up an additional thunderbolt display to all of this? Basically my end-goal is to have a macbook pro hooked up to an iMac with an additional thunderbolt display, that's my "dream set-up" which will make a lot of stuff that I do a lot easeir and less crowded on one moniter.

no the thunderbold display thing would let you use the imac as a monitor for the macbook apart from acting the role of display the imac would be dorment so a very pricy monitor

Macbook Pro Retina trouble with projector after using Thunderbolt display

I used my macbook Pro Retina with my Thunderbolt to VGA adapter all through the fall, and never had any trouble with it. Just before Christmas I got a Thunderbolt display.
Since that time, whenever I connect the projector, I get a black screen. I can see and move the mouse, but nothing else. Other computers still work with the projector.
I'm not certain if the Thunderbolt Display has anything to do with this or not, but it's just the timing that it happened.
Grateful for anyone that can offer help!

It might be that the Thunderbolt output is set to the resolution of the Thunderbolt display, which the VGA adapter probably cannot display correctly. You can toggle between the video display modes using Command-F1... This will toggle the output between Mirroring and Extended Desktop. Using Command-F2 will allow you to attempt to detect displays. It might auto reset to the correct resolution using Command-F2. If you can get the VGA out to display using extending desktop then you can change the resolution to work properly with the VGA projector.

Motorola Hz800 Bluetooth headset shorts out MBA Bluetooth Module when plugged into MBA USB port for charging

This is the weiredest thing. Everything is fine with my MBA, I have an apple bluetooth keyboard and mouse running smoothy then I plug in my Motorola HZ800 bluetooth headset using a USB to mico USB cable to my MBA to charge it and BAM! I get a the bluetooth logo with a sawtooth wave through it. It shuts down the bluetooth module completely. I have to restart the computer to bring back the bluetooth module to life. And now my keyboard won't pair again, but that's a whole other issue. Any reason why this would be? Thanks.

Yes. USB ports are limited to a maximum of 500 ma of current. Check the current rating on the charger for your headset. It is probably higher than 500 ma. It overloads the port forcing it to shut down.

Automatically turn off wifi when plugged into LAN?

What happens:
I go to a site and put my nice MacBook Pro down. I then plug into their wired network and then discover that I am accessing the wrong network. I look up and notice that the wifi is hooking into a nearby access point.
What I Expected:
When I plug in a wired LAN, it should turn off wifi.
Ciao!

is it THAT much of an inconvenience to just click on the wifi symbol in the menu bar and select "Turn Airport Off" ?
I performed extensive experiments and this can be accomplished in under 2 seconds, on average.
I didn't say it's a hardship, but it's something the computer should be able to do automatically. Following rules like that are something computers are good at. I'm not.
Taking the same argument, they could just have a drop down that lets you pick "better performance" or "better power savings" and you could click it your self when running off battery or not. But it makes much more sense to have the computer detect this situation and react accordingly.
Do you have a helpful suggestion?
Ciao!
