MacBook Pro refuses to recognize mouse

Suddenly my MacBook Pro refuses to recognize any mouse.  Any ideas pn what can be done?  I have rebooted and installed new batteries in both an apple mouse and a Logitech mouse but no response from the MacBook.

Have you tried other headphones just to rule out the problem is not with the connector on the headphone? Are all Apple updates applied? Try a SMC reset: http://support.apple.com/kb/HT3964

  • After a year of no use and a fully discharged battery, my MacBook Pro refuses to accept the administrator name and the password. How can I reset these?

    After a year of no use and a resulting fully discharged battery, the MacBook Pro refuses to recognize the administrator name and password (both). It has system OS X 10.6 which can not be upgraded without the information. How can I reset or reistall the administrator name and password?

    Thanks to all who responded. You are all absolutely correct. However, this Ipad was a gift to my wife who was dying of cancer in the hospital and wanted some entertainment. So I started it out with her Apple ID. After she passed away I moved from Sacramento to Austin and eventually proceeded to get the Apple ID changed from my wife's to mine. Meanwhile when she was in the hospital I opened an Itunes account in my name to buy movies for her. That was the first mistake.
    Then during the move to Austin I lost track of the IPAD and later found it and tried to use support but could not remember the proper ID. Later the folks at the Apple store helped me create a new and novel Apple ID that was unfortunately unlike any other.
    The botom line is that I am stuck with three Apple IDs and three passwords. I am told by Apple there is nothing they can do about this as IDs cannot be changed or destroyed. I can quit using them or start a new account but when I try to do that the system keeps remembering too many things from the past and resists.
    Even if I sold this Ipad and bought a new one, the system memory is still there.
    I think the real problem is that destop and laptop computers are totally owned by an individual and that individual can control logins and passwords to his liking. IPADs and similar Apple products are different in that the corporation has built in their own intrusion detection schemes because of the relation to Itunes.
    One thing I thought about is to open a new Itunes account pretendding to be a new customer with my regular Apple ID. Perhaps I could do the same with Apple Support.
    Thanks for your comments.

  • Macbook Pro doesn't recognize iPhone 4Gs

    Macbook Pro doesn't recognize my iPhone 4Gs
    My Macbook Pro 15 (Mac OS X 10.6.8) doesn't recognize my iPhone 4Gs (iOS5.1)
    Suddenly it stopped, last time was April 11 via Wi-Fi.
    Now even with the device plugged it can't be recognized.
    On iPhone Settings, the "iTunes Wi-Fi Sync" tab is grayed.
    Few days ago iPhone started to behave strangely, refusing to power off, sometimes not charging when plugged to USB port, sometimes does.
    Don't know what to do.
    Thanks in advance
    best

    What kind of phone is this? an iphone 4? or an iphone 4S? ( note there is no such phone as an iPhone 4gS)
    What you describe here is in my eyes the beginning signs of accidental damge, such as water damge of some sort.
    This is a great oppurtunity to see if the same issues you are having when connecting to your computer, replicate when conencted to another computer.
    You need to find out if there is a way to test with a new USB cord if possible to rule that out.
    Trying to isolate this to, or away from the iphone.

  • I just created a new profile/user on my MacBook Pro. My pointer/mouse. It works fine in my older user profile, but when I go to the new profile my mac will not respond to clicks. Mouse moves but will not click. Already tried restarting and the pram zap.

    I just created a new profile/user on my MacBook Pro. My pointer/mouse on my trackpad. It works fine in my older user profile, but when I go to the new profile my mac will not respond to clicks. The Mouse moves but will not click. Already tried restarting and the pram zap. The problem starts when I log out of my main profile. I get to the login screen and my laptop stops responding to clicks. When I manage to make my way back to my main profile the mouse works perfectly.  Should I just delete the new profile and try again?

    If the modem is also a router, either use the modem in bridge and run pppoe client on the TC.. that is assuming ADSL or similar eg vdsl. If it is cable service.. and the modem is a router, then bridge the TC.. go to internet page and select connect by ethernet and below that set connection sharing to bridge.
    Please tell us more about the modem if the above gives you issues.

  • My MacBook Pro does not recognize my Android Incredible 2 cell phone and I can not transfer my photos from my cell phoen to my Mac. I was able to do this in the past, but can no longer do so. i havenot upgraded to any new software.

    My MacBook Pro does not recognize my Android Incrdible 2 cell phone and therefore I can not transfer any photos from my cell phone to my Mac. I was able to do this in the past, but can not do so now. I have not upgraded to any new software. My USB cable is plugged in properly and I just get an error message -- "No Android Device Found". What could be the problem?

    I had the same issue with the Galaxy S4 trying to see what the hype was about and was my first and last android phone. With that being said unfortunately it is a hit or miss with the Mac recognizing an android device or not.  It worked perfectly fine the first time around and then it stopped working for no apparent reason. Through trial and error nothing I did solved the issue.   I did however plug it in my Mac and left it connected for about 30-40 min to charge for a bit and all of the sudden it recognizes the phone. So I just launched Android File Transfer and everything else became fluid after that.    I have no explanation as to why it happened that way, but what I gathered from this is maybe you just have to let it sit for a minute while plugged in before the Mac recognizes it, after all they are opposing software.  On a side note this is why I will always be an apple user, Iphones and the like never have this problem

  • MacBook pro does not recognize my WD external hard drive anymore

    I use TIme Machine on my WD external hard drive. Everything was working great up until about a month ago. My MacBook Pro does not recognize my external hard drive anymore...I have done nothing differently than usual. I did search in previous discussions and tried rebooting both the hard drive and the computer.
    The USB port is fine as it does recognize another external hard drive and also pen drives....Please help! I haven't backed up in a month and need to figure out how to get this to work soon. Should I call WD?

    Does the WD drive show in Disk Utility?
    Many times, a USB port simply cannot provide the power a hard drive needs. It is not uncommon for any electric motor to draw more power as it ages. A drive that worked before can stop working when it gets older because age has made it tak more power than any USB port can supply. There are a couple of cheap things to try:
    1) A "Y" USB cable---two plugs go to the computer and one to hte drive, giving a power boost.
    1 Meter USB 2.0 A to 5 Pin Mini B Cable - Auxiliary USB "Y" Power Design for external hard drives.
    2) a POWERED USB hub. That takes the power delivery burden off the USB port so it can deal with data.
    WD bare drives are fine but their enclosures are not very Mac-friendly. One thing that has reported helping is to get rid of the proprietary formating that WD puts on their drives. If you don't have to share the drive with a Windows computer, use Disk Utility to erase and reformat the drive to Macintosh Extended Journaled.

  • My macbook pro will not recognize my WD external hard drive 1tb

    My macbook pro will not recognize my WD 1 tb external hard drive that I have as my time machine backup. I worked just fine for a long time now The only way I can see it is through Disk utility. And when I try to repair the disk it say it cant be repaired, and i need to back up files and reformat. All my backups are on the hard drive. How do I back up the back if I cant get it recognized? Uggghhhhh I have several years of info on the hard drive .. PLEASE HELP!!!

    Hi cterry66,
    Welcome to the Apple Support Communities!
    I understand you would like to reset the user account password on your computer but do not know the original password. If you set up your Apple ID with that user account, you can use that Apple ID to reset your OS X user password. Please use the information provided in the attached article to complete the process.

  • My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you

    My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you think it is? It won't recognize any hard drive I put in the machine, so might it be the sata cable?

    Boot the Recvoery USB, use Disk Utility to select the internal drive makers namea and size on the left.
    Now select erase and select the midde option and click erase, it will take a bit to complete but it's best for the drive.
    Now select Partiton tab, click the big box and Options: GUID and then Format: OS X Extended journaled and click apply.
    Quit and you should be able to install OS X now with your Apple ID and password.

  • MacBook Pro won't recognize 1TB external drive

    Hey team,
    My mid-2010 MacBook Pro won't recognize my WD My Passport 1TB drive.  I was copying files from the drive to my computer when my computer went to sleep (didn't run out of power, just went to standby mode).  Turned computer back on and now it won't recognize the drive.
    It is a USB 3.0 cord (computer is only USB 2.0 and the cord works with other drives) and when plugged in, the light turns on and the disk spins but isn't recognized my this or other computers (also not in Disk Utility).
    Tried a handful of disk recovery programs but nothing wants to 'see' the disk plugged in.
    Thanks for any and all suggestions.

    yes yes yes,   I warn people about WD drives on this link:
    Your dead external hard drive is likely fine! Great hope for your 'faulty' external HD
    theReKleiner wrote:
    What now?
    Only option is to buy the SAME exact HD and swap controller boards,  or pay someone a LOT more $$$ to do the same thing.
    its not soldered there, its just a controller/ SATA  "one piece"
    They do that to save 50 cents in mfg. costs.
    I mention your "issue" in that link.    Which is why you do NOT buy WD ext. HD.
    they make the controller board and SATA card one piece. 
    CURRENT MFG. THAT HAVE controller board and SATA cards as one piece are :  WD USB drives, and Toshiba USB Canvio
    However Toshiba didnt USED to do that, but they started doing it at the end of 2013.
    avoid those 2.
    To avoid that nonsense, buy Hitachi drives in USB.
    Or, the best option:
    Save money and invest in a bare hard drive backup and redundancy plan
    Its cheaper
    less fuss
    more reiable, removes the nasty failure point of SATA card interfaces.
    takes up lot less space.
    Bare hard drives and docks. The most reliable and cheapest method of hard drive data storage, archives, and redundancies
    The best method for your data archives and redundancies, which is also the least expensive, the most reliable, and the most compact option is the purchase of naked hard drives and at least one USB 3.0 HD dock ($40 roughly).
    While regarding Time Machine and your Macbook or desktop, your primary backup is best saved to a conventional USB (or Firewire / thunderbolt) hard drive inside an enclosure, the most important part of your data protection begins after your 1st / primary Time Machine / backup; and these are your secondary (most important) data storage devices, archives and their redundancies.
    However bare hard drives and docks (below) also work perfectly as a Time Machine backup, this is for home use, since the docking station is certainly not very portable as a notebook Time Machine backup device should be; nor should bare HD be packed around with a notebook, rather remain at home or office.
    Six terabytes of 2.5" HD pictured below in a very compact space.
    Bare hard drives and docks have the lowest cost, the highest reliability, and take up the smallest storage space
    Drawbacks:
    1. Care and knowledge in general handling of naked hard drives (how not to shock a bare HD, and how to hold them properly). Not a genuine drawback.
    Advantages:
    1. By far the least expensive method of mass HD storage on a personal basis. Highest quality naked HD can be purchased in bulk very cheap.
    2. Eliminates the horrible failure point of SATA bridges and interfaces between external drives and the computer.
    3. Per square foot you can store more terabytes of data this way than any other.
    4. Fast, easy, no fuss and most simplex method of data storage on hard drives.

  • MacBook Pro doesn't recognize iPhone when USB connected

    I have a MacBook Pro, an iPod, and an iPhone.  Using the same usb port and cable I have the following situation.  The MacBook Pro recognizes both other devises in iTunes through the internet.  The MacBook Pro does not recognize the iPhone 5 when connected by cable but does recognize the iPod.  Because of this I can't transfer photos from the iPhone to the MacBook Pro.  When connected the iPod shows it is charging but the iPhone 5 does not.  Using the same cable connected to the wall charger both devices show they are charging.  Does anyone have a suggestion?  Thank you.

  • Macbook Pro doesn't recognize audio cd's after Yosemite upgrade

    After completing the upgrade to Yosemite, my Macbook Pro doesn't recognize purchased audio cd's.  Help!!

    hi russeel!
    when i first upgraded to 5.0.1.4 i panicked for a while looking for that tab (and the Burning one) ... the subtab that i find kind of strange is "Advanced-General". Generally Advanced? Not Tremendously Advanced?
    okay, we've gone up a

    of versions in your case (nearly as many as it is possible to go), so we'd probably better check through some of the usual suspects. let's start off with this document:

  • Macbook Pro doesn't recognize Flip Mino camera in USB port after Yosemite upgrade

    Since I upgraded to Yosemite, my Macbook Pro doesn't recognize my Flip Mino camera in the USB port.

    I don't use FLIP, but if you get no other help here,
    consider the following ideas.
    If neither restarting your Mac
    nor reinstalling OS X fixes your
    problem, you might find some
    help if you search or post in the

  • Macbook pro doesn't recognize camera on image capture

    My MacBook Pro doesn't recognize the built-in camera for a lot of my applications, including Image Capture. It doesn't show up anywhere in my system preferences. Any idea why this is so?

    (1)  Mac's built-in camera does not work with Image Capture.
    Image Capture works with external devices like scanners, some iOS devices, some cameras and RAM cards, etc.  Click this link for more info about Image capture and some of the apps that can work with your inbuilt camera.
    Click here for info about how to use Image Capture to transfer images from a connected external camera.
    For more info about Image Capture functions, see Image Capture > Help on your Mac or the Apple pages in this link.
    (2) To test for application-specific problems mentioned in the "How to Troubleshoot iSight " article, use apps like Photo Booth, QuickTime Player, iChat, FaceTime, or others intended to work with your Mac's inbuilt camera.
    (3) To test for user-specific problems mentioned in http://support.apple.com/kb/HT2090 the "How to Troubleshoot iSight " article, you must have more than one user account.  Do NOT use the "Guest" account.  Click this link if you need help creating new accounts for testing.
