6/9/11 update old usb keyboard no longer works with macbook pro

Hi I have been using my old Imac usb keyboard with my macbook pro at work since I got my macbook pro. But as of yesterday I have not been able to use it anymore. Any suggestions to a fix or do I have to buy a newer keyboard? I need the numbers pad to entering data.
Any suggestions would b great.

Your message would be easier to decode if you had proofread it before posting.
Does your keyboard work when the mouse is plugged directly into the computer instead of into the keyboard, or does the keyboard not work at all? If not at all, then it sounds as though you're right in guessing that the keyboard isn't getting power for some reason (bad cable? bad connection inside the KB? USB port on computer shut down?) If the KB works when the mouse isn't plugged into it, then the mouse and KB together are demanding more power than the computer's USB port can supply, and neither is getting what it needs when the mouse is connected to the KB. In that case, plug the mouse directly into the computer to use it.
The USB port in your keyboard probably doesn't put out enough power for the mouse you are using. This is typical of older keyboards, which were designed to power old-style electromechanical mice rather than the laser mice that are commonplace today.

Old MagSafe Airline Adapter not working with MacBook Pro Retina

I've got an old MagSafe Airline Adapter (one I bought when it first came out) that I'm trying to use with my MacBook Pro Retina (using a MagSafe to MagSafe 2 Converter). Sometimes the light is green, sometimes it is off, sometimes the battery icon in the menu bar shows plugged in, sometimes not, but in any combination, the machine is not maintaining charge; the battery discharges at a normal rate for just being on battery. For giggles, I borrowed my seatmate's year-or-two-old MagSafe adapter (the one with the right-angle plug) and plugged it into my machine (also using the MagSafe to MagSafe 2 converter). The light on that one turns orange, and though the battery icon shows "Not Charging", the battery is maintaining charge with the newer adapter. (My adapter, BTW, is able to maintain the charge on her 13" MacBook Pro.)
Was there a change to recent versions of this adapter to make the new ones work with the Retina MacBooks where the old one will not?

the green light on the mag safe turns on?
you should reduce your usage to a very minimal amount as I'm sure the airline doesn't output a strong enough signal for you to be running full screen films with high res. Maybe you should close your macbook P and see if it is charged after a little while of not using it.
turn your screen lights down, turn the sound gHZ down, quit all the downloadin'.
if you must run flash make sure you have the latest version (from the adobe site).
You're computer is intense and if you use it more then it's gaining, of course it going to be draining .
But this is probably moot since you're probably on said plane now. or was.
I'd imagine if you're not satisfied with the product you should return it detailing your situation.

Garagekey USB keyboard works with MacBook Pro, but not with 27" iMac

Just got a brandnew 27" iMac. The Garagekey USB keyboard doesn't work. It's recognized in systemProfiler, Audio-Midi Setup, GarageBand and Logic. But no Midi is coming in. When I plug it into my MacBook Pro, it works immediately. I know the Garagekey doesn't work with some 3rd party USB hubs, maybe for lack of enough power, but it works always at the internal USB hubs with the MacBook Pro. Why doesn't it with the 27" iMac? I'm cueless...
The IMac Systemprofiler says: Current Available (mA) 500, Current Required (mA) 300. So I guess, it can't be a power problem?

Have the same problem with Logic Pro. Works on my old Mac Mini but not on the new iMac 27" i5. Apple told me that it is a difference between the boards they used on the two computers. They said that even if I got a new mac mini I would run into the same problem. they recommended that I upgrade my mini, or try another piece of hardware to connect the two. Looking for hardware now. Good luck to you.

Apple USB keyboard does not work with one internal usb port

Hi everyone,
hope someone can help me to solve my problem. I have a MPB13 retina late 2013 since something like 3 months. I have additional screen (dell), usb wired keyboard (apple) and BT magic mouse.
Since a few days, my usb keyboard does not work well. It only want to work properly when plugged to the rights side usb port internal port and not anymore on the left one. It also work on a usb external concentrator. Before, I had no problem, it worked perfectly. There was no problem such as cofee on it...
After searching the web on such problem, I tries a few things such as:
I tried the keyboard on another computer (windows): works fine
I tried usb stick and external DVD reading on the left internal usb ports: works fine
I switch the MPB off and turn it back on: the usb keyboard still does not work on the left usb port
I tried the SMC and PRAM reset : nothing
Any idea ??
Thanks
Guillaume

I'm facing the same problem, found any solutions ?

Hi and welcome the forum!
Try uninstalling all USB hub devices from the device manager and reinstalling them again, particularly the keyboard's.

Apple USB modem no longer works with Mountain Lion

Now that I've upgraded my iMac to Mountain Lion my Apple USB modem no longer works. Does anyone know of a software fix or have I just lost my faxing ability with this item and have to buy something else?

That's a very sad situation as the Official statement link above (http://support.apple.com/kb/ht3152) states that the modem cannot be used with any Windows. So Apple thinks that people investing in the ability to Fax and relying in Apple's good product only deserves to throw out their modems (because now it is useless on any platform)...

USB Mic no longer works with Skype after 7.1 updat...

Using a USB headset with skype, worked with previous versions, works with other programs. I can hear people talk but they can't hear me! Skype detects the mic just fine but when I talk nobody can hear me.
I have tried updating drivers, re-installing skype, I have tried deleting my profile/preferences from the skype folder on my PC and starting from scratch, tried restarting my computer, re-installing my headset drivers, and tried restarting or re-plugging in my mic. Nothing works. Skype simply doesn't use my mic properly in the new version, previous versions did not have this problem, as I said mic works fine in all other programs.

Hi pa.elimination, Can you please reproduce the issue and provide logs as described in this link https://support.skype.com/en/faq/FA12321/how-do-i-create-log-files under Skype for Windows Desktop and attach it to your post?
This will help us investigate and solve the problem you are experiencing.
Can you also try with the 7.0 version to see if that version solves your issue?

Extended keyboard no longer works with some games

I've searched the discussion groups; can't find an answer. Some games that used to work with my Power Mac G5 start up fine, then going into the mission/action/etc. my extended white wired keyboard stops working (no keys work at all). The mouse works, but not the keyboard.
So far the games affected are Battlefield 1942, Medal of Honor, Myth II and III, and the new game, Babylon 5: I Found Her. Ghost Recon works fine, just in case someone wants to say its the game.
I've tried resetting PRAM, opening in Safe Mode, plugging the keyboard into the other USB port, and deleting all the game plist files. All these games worked before with the same hardware, but before 10.5. Anyone have any ideas? Thanks.

Thank for responding. I'm running 10.5.6; haven't "updated" since I know there are problems. I can say for certain that those games worked fine under 10.4.x. Also other games work fine, and I have no access to another keyboard. I'm convinced from its behavior that something in the 10.5.x series is the problem. That's because the keyboard works fine with those games while setting the options, selecting missions (e.g.), but when the map downloads (or other starting function) and it's ready to go, the keyboard stops working (or, more precisely, the game no longer recognizes input from the keyboard). The mouse (connected to the keyboard), works.

Wireless keyboard initially works with macbook pro, but then freaks out!

i just started using a wireless keyboard and wireless mouse with my 2-year old macbook pro, and while it all initially pairs up and works fine, after about 10 minutes weird things start happening.....like the tilda button seems to suddenly get stuck and repeats itself until i push it down, or my browser windows starts jumping to fill the screen. it still keeps working, but the freaking out on my screen gets worse.
i first unpaired first the keyboard and then the mouse to see which was causing the problem, and it seems to be the keyboard that's the culprit. the battery level seems to be fine, and as i said it seems to be paired correctly when i double check it under bluetooth in sys pref. also checked the keyboard viewer in sys pref and that seems to be working ok. i've done some searching on apple support and in discussions but can't find any similar situation. (also couldn't find a discussions category for keyboard, or would have posted this there)
i would greatly appreciate anyone's thoughts/suggestions on this!

I am having a similar problem with the wireless keyboard. Initially it will work, but then I'll come home and my computer speakers will be beeping because the wireless keyboard is trying to type something from across the room. Additionally, when I try to use my regular onboard keyboard when this happens, its impossible because the wireless keyboard is constantly typing something. My only way around this is to turn off wireless keyboard and only turn it on when I need it. Please post back with your results. Any ideas of how I can fix this?

Trackpad no longer works on MacBook Pro after update to OS 10.72.2

I just did a software update to OS 10.7.2 and upon restart my trackpad no longer works. The button does but not the pad. Any thoughts? I have never had a problem with it. There is no battery issue. No buckling or swelling. It worked, then I updated it to 10.72, restarted, and now it doesn't.
I have a MacBook Pro, 2.6 GHz Intel Core 2 Duo with 4 GB SDRAM.
Thank God I have an external mouse. HELP!

Apple wireless keyboard no longer working with boot camp Windows 7

Hi,
I've had Boot Camp installed for about half a year now with no problems.
Yesterday my wireless keyboard stopped working with it, it also appears that bluetooth isn't in the device manager or in the control panel, it could no linger detect either my magic mouse or keyboard despite having fresh new batteries. They do however still work with my Mac OSX partition. It also lets me hold down alt to choose which OS to boot into on startup however when it gets to the log in screen for windows the keyboard stopped working.
I've tried unpairing them in OSX then trying it in Windows but like I said bluethooth doesnt even appear to be there and it wont detect them. I've also tried reinstalling the apple drivers twice, still doesn't work.
If it helps I have a early 2011 iMac 21.5inch and it's Windows 7 Ultimate 64 bit.
Thanks,
Dan

This may be just a Boot Camp issue, if no one here can help you may also want to post in the Boot Camp forum.

FCP Pro Keyboard number keypad not working with Macbook Pro

Switching over to a macbook pro I find my Pro Keyboard number pad has stop working, infact if I try to use it it crashs my computer
any help?

maharitho wrote:
have you tried to repair your permission, and restart mac maybe it works
Kinda hard to do that if the keyboard and trackpad isn't working - don't you agree?
In any event - what were you doing last before your keyboard and trackpad stopped functioning?
Did you do any upgrades to your Macbook?
Have you tried doing a PRAM/NVRAM or SMC reset?

WRT610N updated firmware, USB Harddrive no longer works

Hello everyone,
Thanks in advance for any help you may have. I've seen that a few people have had this problem, so maybe there is a fix. I have updated the firmware to Ver.1.00.02.10 because the release notes said that it had improved USB harddrive function. I updated the firmware, held the reset button, power cycled, restored my configuration, replugged my USB drive & turned it on. I still am unable to access the USB drive. It just does not show up.
My harddrive is a Maxtor One Touch 750gb, works perfectly when directly attached. I have 2 pcs (one connected via gigabit and the other via N), both working great.
Any thoughts?
Thank you so much in advance.
-Tim

Solved!
Go to Solution.

I have had a similar problem. The drive I am using works when connected by USB to my other computers but I can not set up a share with the router now. It use to work, I haven't checked but is there any place where I can download an older version of the firmware?
Thanks
