Unable to pair previously paired Magic Trackpad

I've had my Magic Trackpad previously paired with my other MacBook Pro without issues.
I reformatted it and installed Mountain Lion on it, without unpairing first.
My wife inherited my old MacBook Pro once I got my new MacBook Pro Retina.
Now I wish to pair the Magic Trackpad with my Retina but it's never discovered!
It's got a fresh pair of batteries and the green light comes on but it never starts to blink.
I tried it on my old MacBook and it has the same issues.
Tried both System Preferences / Trackpad & Bluetooth - same result.
Help?
Thanks!

Yes, I'm aware that it has a built in trackpad...
I'm using my MacBook on an mStand sometimes and it wouldn't be very ergonomic if did'nt use a external mouse... ;-)

After pairing in Bootcamp, magic trackpad does not work

after pairing in Bootcamp, magic trackpad a) does not control cursor and b) does not persist after closing Bluetooth devides dialog.
Summary of Problem:
Magic Trackpad is found and paired, but does not control the mouse.
When you shut the Bluetooth devices and reopen (or reboot and reopen), the device is not listed.
Detials of problem:
Bootcamp 3.1 (i cannot find a later one) Windows XP all updates, All Apple Software Updates (to bootcamp and mac os x) installed, Magic Trackpad driver download and installed.
Control Panel, Bluetooth Devices, Add - it detectes the magic track pad (ie track pad blinking, click add) everytime
- It asks about a pass code, I have tried it without a pass code and with automatically Generate Passcode; does this setting matter?
In bluetooth devides, the track pad shows with "Auto Generated passkey" when that is the option selected
Found new hardware comes up, Apple Wireless Trackpad, everything looks fine.
- In Bluetooth Devices, it shows the trackpad wiht "no passkey", even when I told it to automatically generate one.
The track pad does not control the cursor.
Close Bluetooth Devices and reopen it, or reboot and reopen Bluetooth devices, and the track pad is gone.
Rebooting does not change the outcome of above.
I have gone to device manager and tried to update the two (apple & microsoft) Bluetooth drivers with the update button, it says I have the most current.
I do not see how to tell if the Magic Trackpad driver is installed, so I tried installing it again. It does appear to be listed under HID in device manager.
I have done a lot of googling, wasted a lot of time, if I cannot get it to work, I will return it to the apple store.
Any ideas?
Thanks!

Bob, cannot help directly but I am having a similar problem on my MacBook Pro with Windows 7 Pro. Pretty much the same symptoms except my trackpad is not always recognized - it seems I have to click it to get Bluetooth to see it. Windows claims to have seen it OK on one occasion and installed the drivers, asked for a reboot etc. but the TrackPad still does not respond.
Works OK on the Mac side although it is not recognized as a separate Bluetooth trackpad which can be configured differently from the built-in. I wonder if this might be a clue?
I have installed the patch and tried a bunch of other things. Seems like Apple has some work to do sorting out the bugs on both the Mac and Windows side with this device. Pity because its an excellent piece of kit otherwise!

My mac pro won't pair with my magic trackpad.

I'm posting in this forum because I am using a Mac Pro, what we used to call a "tower," and my Magic Trackpad isn't recognized & won't pair. This has been an increasing problem over the past year, and I actually blamed the trackpad and bought a new one -- and of course it doesn't work either. My MacBook Pro (actually two of them) use the same latest version of Mountain Lion and they pair up just fine, never dropping the connection. I'm an old-timer with 25 years on the Mac, and I'm stumped. The support forums here confirm that this is a common problem -- MT not pairing -- and I have tried every suggestion I can find. Booting in safe mode, repairing permissions, trashing the bluetooth prefs file, VRAM and SMC resets, moving computer away from any possible interference, and probably two or three more I can't recall. I don't have any exotic apps installed (there's one that has something to do with Windows that can cause this problem, but I don't have it), nothing on the tower that's not on the two laptops running the same OS X version. For the record, I have a 2x2.8 Quad-Core Intel Xeon, 4 GB 800 MHz DDR2 FB-DIMM, all the original Apple installation. OS X is 10.8.4. I've tried three different brands of alkaline batteries. For a time the problem was intermittent (the dreaded "dropped connection") but now it doesn't pair up at all, i.e. neither of my two trackpads pair up. I've let the "searching" function run for as long as 30 minutes, including some restarts of the trackpad...you get the picture. Although this has been addressed in other places in support, I am posting here because so far I don't have a solution. Any ideas? I really appreciate the forum, have been here a long time, and hope that someone has that next good idea that's going to help me. Thanks in advance!

I had the same problem as you with Bluetooth stuff. It was suggested to me that I buy an external BT dongle
as the bluetooth reception in the stock Mac Pro was spotty at best.I did so- iogear 421 (the 521 is supported but ONLY in Mountain Lion, so I was told) and bluetooth works just fine. Of course it might be that the cables for your Bluetooth/Airport card in your Mac Pro could have been installed incorrectly (just google bluetooth in Mac Pro help) but...if they have been, then the dongle might be your best bet, or some kind of external antenna
(the G5 had one, as you may know, but we don't......)
I see by your posting you have tried every suggestion you possibly could, and it's not software related
and it's not a simple one-shot-done fix...
that's the best I have for now. I think I paid about $25 for the dongle and it was easy as pie to install

HT202731 How do I find pairing code for Magic trackpad. Running bootcamp to enable windows and asking for pairing code...

I'm running Bootcamp on my iMAC. It finds the magic trackpad but asks for pairing code. I've looked on the trackpad and in the paperwork that comes in box - no pairing code. How do I find this so that I can use the device with my iMAC. Help appreciated. Many thanks

Unable To Pair Magic Trackpad

Hi there I bought a Magic Trackpad pad from the Apple store in Exeter yesterday and so far I have been unable to pair it to my iMac.
The instructions tell me the open system preferences and select "Magic Trackpad" but it's not there for the to click on. As far as I know I have the latest version of OS X as I just checked the software update and I didn't say there was anything new for me to download.
So what do I need to do I'm guessing there's a new update for OS X that I haven't found yet?

You need 10.6.x to use the Magic Trackpad, you can find out what version you are using by clicking the  in the upper left of your screen and then clicking on About this Mac. Once you post that then we can start trouble shooting. Until then it's anyone's guess. While you are at it please post what iMac you own too. You can find that information by going to this site and inputting the serial number of the machine. You can also find that under the About this Mac by clicking the version a couple of times.

Finally a good place to start is by reading the documentation that came with your MT and closely following the instructions.

Pairing magic trackpad with Macbook10.5.8

Unable to pair my Macbook with the magic trackpad. It prompts me to enter a passkey into the "device" to complete the pairing process. I have no idea how to enter the passkey onto the magic trackpad. All I know is if the green light blinks it is ready to be found.

Good idea to follow the manual.
http://manuals.info.apple.com/enUS/Magic_TrackpadUG.pdf
The key you are being asked to input will be done on your keyboard. This is to make sure you're pairing with the correct device.

New mac mini - magic trackpad - won't do initial pairing (hence no anything

So I just got a Mac Mini server, and I've only had laptops in the house up until now (so no USB keyboards or mice), so I got a Magic Trackpad and the wireless keyboard. Upon booting for the first time, I get the expected image to turn on the wireless mouse to pair, so I turn on the magic trackpad and... nothing. I turn it off, I turn it back on. I turn it on and hold the power button. I turn off the MacMini and restart and try again. I do a little dance to the Bluetooth spirits, and still nothing. Anyone have any ideas aside from go out and buy a wired mouse? (Note: I cannot go to preferences, as I cannot get past this initial waiting-for-bluetooth-mouse-screen.)

Probably, it is because the Magic Trackpad requires at least 10.6.4 (and an additional update), or 10.6.5 (out of the box): so, if the install disc is only 10.6.3 or less, maybe it won't detect the trackpad.
You could try first with a wireless (for example, the Magic Mouse works) or wired mouse, and install the trackpad afterwards, after having updated the OS to 10.6.5.

Macbook Pro and Magic TrackPad don't pair correctly

Hi
Today I bought a Magic Track Pad and tried to pair it with my Macbook Pro (early 2010, running 10.6.8).
The steps i did:
1. Open System Prefernces > Trackpad > Confige Bluetooth Trackpad
2. Turned the Trackpad on (After a second it was blinking, as it should)
     - http://cl.ly/3k2Y0N200F3C1X3Y3S1K/Screen_shot_2011-08-05_at_12.47.30.png
     - so far so good
3. Clicked on "Continue"
4. Got this error message: http://cl.ly/451t241v3m2W1E3J173L/Screen_shot_2011-08-05_at_12.47.52.png
5. Clicked on Continue with the following message: http://cl.ly/3E3u2t0h2X3K3h0k1y0b/Screen_shot_2011-08-05_at_12.48.08.png
      - the setup doesn't find the trackpad anymore
6. The Trackpad works as mouse but without the multitouch gestures.
7. It appear in the bluetooths settings: http://cl.ly/1B3I362D36263i121B3g/Screen_shot_2011-08-05_at_12.48.33.png
Before you ask:
Afterwords I tried nearly every other connecting order
My system is up to date
I tried a restart
I downloaded the update "Magic Trackpad and Multi-Touch Trackpad Update 1.0" - the setup don't want to install the update: "not necessary"
The Trackpad works perfectly with another Mac (plastic-unibody Macbook from 2009)
So what should I do? Any idea?
Regards
Fabian

In cases like this, many times there is a conflict with 3rd party apps. USBoverdrive seems to be the most frequent. If this doesn't apply than try a pram reset and a SMC reset.

Magic Trackpad Pairing Number?

I am trying to use my Magic Trackpad in Windows 7. I'm using BootCamp with the Magic Trackpad 1.0 update. When I turn on the trackpad, it asks for a pairing number. Where can I find this or get around this?
Thank you for your suggestions.

Try 0000 or look in the user manual or a simple Google search.

Magic trackpad won't pair

Just bought a magic trackpad and I can't get it to pair with my mac mini.
I have a 2009 mac mini running lion with 8 gigs of ram.
I turn on the trackpad and the light begins to blink , and then I click the
track pad button in system preferences but it never finds the trackpad.

Never mind!
I restarted the computer and tried it again and the trackpad was quickly paired.
So, all is right in the world.
Thanks

Magic Trackpad - Pairing Problems Switching Between OS X & Windows

My system has Mac OS 10.6.4 (with Magic Trackpad update 1.0 installed) and Windows 7 (with Bootcamp 3.1 plus the "Magic Trackpad/27" Cinema Display" update). The Trackpad works correctly after setup in OS X with all functions working even after reboots. The Trackpad also works correctly after setup in Windows 7 (with passkey 0000) and continues to work correctly with the supported features with multiple reboots into Windows 7.
The problem is that after using Windows, when I reboot to OS X the Trackpad will not function. It shows as paired but disconnected and will not stay connected. If I un-pair and then re-pair it will work. And the same thing happen when I switch from OS X to Windows - it shows as paired but unconnected and the only way to get it to work is to un-pair and then re-pair.
I had a similar sort of problem with the Magic Mouse and found that if I un-pair in OS X, pair in Windows, and then pair in OS X it will work with both. But the Trackpad won't work this way, even after trying this. I think the problem is that the Trackpad won't allow paring with two different systems (for the obvious reason) but isn't designed to accommodate the Bootcamp scenario.
I really like the Magic Trackpad and would like to be able to use it on those rare occasions when I need to use Windows without the hassle of reinstalling it each time I boot a different OS. Any solution to this problem?

UPDATE: I installed Vista on Bootcamp and tried the Magic TrackPad driver. It has the same problem. I can get the device to work as advertised on the initial install and reboots in the same OS. But when you switch from Windows to Mac OS X (or vice-versa) the device will not work: in Windows is listed as paired and connected, but does not work. In Mac OS X, it will not connect automatically and does not work. If you manually try to connect the Bluetooth icon briefly shows connected and then disconnects.
I sent a bug report to Apple as a "developer" and they state that it is a known issue. I guess we simply wait for them to get around fixing the drivers at some point in the distant future. Clearly they ignore these forums altogether. The experience has left me disappointed with Apple and their slow and inadequate response to problems. I would rather they devote some resources to getting their existing products to work instead of wasting resources to add iPhone-style displays to Mac OS X. If I wanted buggy drivers and no support I should have just stayed with Windows.

Magic Trackpad pairs with Bootcamp (Win7) MBP instead of another MBP w/Yosemite?

I've 2 MBP's - a Yosemite MBP and one running Win7 via Bootcamp. When the Yosemite MBP is off, the Magic Trackpad pairs with the old MBP (Win7/Bootcamp). I see no clear way to disable this pairing in Win7/Bootcamp or a clear way to disable Bluetooth on the Bootcamp/Win7 MBP either. I can shut down the Win7/Bootcamp PC, but this gets old very quick, as I tend to carry my Yosemite MBP w/me at the end of the day.
Any suggestions from the Mac Geniuses? Thank you.
Martin

Based on the multiple issues, I think I would reinstall OS X 10.10 from the recovery disk (your data is untouched). As always though, make a good backup before doing anything (I use Time Machine and I also make a bootable clone).

Magic TrackPad wont connect in bootcamp 4. Windows asks for a pairing pin

I am running bootcamp 4 and using a 32 bit version of Windows 7. Every time I try to connect the Magic Trackpad it loads the the drivers but when I go to use the pad it says a bluetooth device is trying to connect and asks for a pairing pin. Is there an updated driver for BootCamp 4?. Magic Trackpad connected and worked flawlessly (as usual) in Mac OS X Maverick.

UPDATE: I installed Vista on Bootcamp and tried the Magic TrackPad driver. It has the same problem. I can get the device to work as advertised on the initial install and reboots in the same OS. But when you switch from Windows to Mac OS X (or vice-versa) the device will not work: in Windows is listed as paired and connected, but does not work.

Magic trackpad will not pair

I have OS 10.8.3 with a magic trackpad. I removed USB overdrive and trashed my bluetooth preferences and still I can not get the trackpad to pari. Followed the instructions from this link. It had paired in the past but this morning I lost the device. I removed it from the bluetooth list and tryed to re-connect. Nothing appears to work. This trackpad works on my iMac, so it is a know good device. (I have since un-paired it fromt eh iMac)
Any help would be great.

I found I had the same problem... Was your trackpad hooked up to different computer in the past? Mine was, after I removed it from my old computer, it worked fine....

HT4254 It keeps telling me that pairing attempt was unsuccessful when trying to pair magic trackpad. Please help

I'm not seeing the Silverlight plugin in your More system details list, so Firefox doesn't find it if you have it.
I assume that you also do not see it in Tools > Add-ons > Plugins ?
