Mac Book Pro (3 Jahre alt): Mouse (Touchpad wie externes Gerät) springt unkontrolliert

Brauche dringend Hilfe. Seit gestern springt meine Mouse (Touchpad wie auch die extern angeschlossene) unkontrolliert auf dem Bildschirm rum. Kann nicht wirklich arbeiten. Ständig klickt sie irgendwas an und bewegt sich eben auch, obwohl ich meine Hände nicht mal in der Nähe vom Touchpad oder der Mouse habe.
Kennt sich jemand mit diesem Problem aus? Gibt es irgendwas, was ich tun kann, bevor ich in den Laden rennen muss?
Danke!

  • Mac book pro freezes keybord and mouse at random, and on startup with batt.

    Hey
    I have been using my MBP for a little less than half a year now, working just fine.
    Lately though, It freezes (mouse and keyboard) when running/starting with battery in (AC or not). restarting doesn't help and i have tried to hold the start button during start, some times that would work. But the last few times it didn't help either.
    No programmes are affected (keep running, iTunes etc.) during keybord-mouse-freeze.
    If take the battery out and starts with AC only, works like nothing ever happend, But if i put it back in after startup, freezes again. hadwaretest says nothing is wrong. Please notice that this is the old Mac book pro.
    How do i fix this problem, and what is it. Anybody knows ? ...

    "...I have not yet opend (ecept the battery out) the computer physicaly, so... "
    I would get it to an Apple store or authorized Apple repair center. You are still covered by the 1 year warranty. Consider purchasing AppleCare to extend that an additional 2 years.

  • I transferred data from my external hard drive to my restored Mac Book Pro via migration assistant and now my external hard drive in time capsule has red minus signs. How do I get rid of that without getting rid of any of my data?

    I used Migration Assistant to transfer my data from my external hard drive via Time Capsule to my restored Mac Book Pro. When I now go into Time Capsule I there are red minus signs in the corner of all the folders that are contained in my back up. How do I get rid of this and access my previous back-ups?

    Select the drive and Finder > Get info and at the bottom "ignore permissions on this volume"
    You can copy the files, but the ownership on the files still belongs to the other user account, once your done copying, then perform a #6 Reset Users Permissions and that will set all the ownership to that account.
    ..Step by Step to fix your Mac
    Another method is to copy the entire folder, then change it's permissions.

  • Why won't my mac book pro recognize my external hard drive?

    I'm having a battery issue with my computer, and need to bring it to the nearby Apple Store to have the battery looked at and possibly changed. I wanted to back up  my computer in preparation for my visit, but for whatever reason, my Mac Book Pro is not recognizing my trusty LaCie external hard drive, a device I have used with this computer for two years now and performed countless backups with. I am not sure why this is happening. I have already tried restarting the computer multiple times, and unplugging and replugging the hard drive, both to no avail. Are there any ways I can get my computer to recognize my hard drive in order to perform the backup? Thanks.

    Hi all -
    I cannot view my flash drive OR my office server, which I should be able to connect to via VPN. VPN was installed on my Macbook Pro at my office on Friday. It worked fine. Now I bring it home, and I connect using VPN, and it shows that I am connected, yet the server hard drive icon does not appear on my desktop (as it usually did) and I can't see how to access the server at work.
    I also cannot view flash drives when I plug them in - they just don't show up.
    I had Norton installed; I read online I should disable that. I did this, and no luck. I also have already done all the things suggested on this post and have all the boxes checked, and yet, still cannot use a flash drive or access my work server.
    I am stuck? Do I have to bring my Macbook pro in for service? I have NOT upgraded to Mavericks.
    Thanks for any help.
    I am not that well versed in finding my way around a Mac - so keep any explanations simple, please.

  • How do you Control Alt Delete on mac Book Pro keyboard when using VM Ware?

    This must be the stupidest question I'll ever have to ask...but....normally in the office I have a separate mac keyboard/screen/mouse and log into Windows via VM Ware. I am using the latest Mac Book Pro model. I have to click on the window and press Control Alt Delete before I log in. This works fine until the day I was out of the office and had to press Control Alt Delete via the Mac Book Pro's own keyboard and nothing happened. I passed the laptop over to 2-3 other mac friendly people and we all were left scratching our heads.
    Can anyone shed some light on this??
    Kris

    Google is your friend!*
    Turned up another Apple Discussions post that said to press  + U at the ctrl-alt-del prompt to bring up the 'visually challenged' tools, and to turn on the on-screen keyboard. This should allow you to log in, then once you are in, remap the keys to something more convenient, maybe assigning the right-hand-side command key to DEL. Unfortunately, I haven't used a Windows PC in ages, so I can't tell you how to do this.
    On a related note, I've just discovered that I don't have an  key on my MBP. You learn something new every day!

  • I am having trouble getting my My Mac Book Pro 15" Retina to wake up with an Apple Bluetooth Keyboard and Mouse while Docked in a Hengedock vertical docking station.

    I am having trouble getting my My Mac Book Pro 15" Retina to wake up with an Apple Bluetooth Keyboard and Mouse while Docked in a Hengedock vertical docking station. The Keyboard and mouse work great with the laptop lid open but when closed in the docking station the bluetooth signal does not seem to transmit.  Is there a setting that can be changed to allow an Bluetooth keyboard and mouse to wake the computer while docked?

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

  • Mac Book Pro on boot up, the apple sign will appear with the spinning wheel.  After some time, a grey screen wil appear with a movable mouse, but will not boot up.  Help!

    Mac Book Pro on boot up, the apple sign will appear with the spinning wheel.  After a period of time the screen will turn grey, but the mouse will still operate, but not boot up.

    If it was purchased brand new then it's running a version of Lion, so to reinstall Lion:
    Reinstalling Lion Without Erasing the Drive
    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
    Reinstall Lion: Select Reinstall Lion and click on the Continue button.

  • Hi all, my mac book pro boots up, but my track pad operation is strange, cannot click on anything, although it moves around screen ok. Cannot launch anything, nor close anything. Cannot get task bar to pop up either with the mouse movement.

    Hi All,
    My mac book pro 13". It boots ok and skype launches on boot up. connects to internet etc. However, whilst the mouse moves around the scren ok, used via the track pad, I cannot open anything, close anything, or get the task bar to pop up.
    I can close the laptop down via the power key, and can use some short cut keys, but the track pad operation is iffy, can you suggest how I rectify this.
    I have now solved this, for future reference, I have a magic track pad as well and that was connected via bluetooth and sitting else where in the house. It blocked the laptops trackpad operations. When disconnected, my laptop track pad works fine.
    Cheers

  • Mac book pro (late 2013) has a lag when sculpting and rotating models in Zbrush only when using my Wacom-capture tablet (if I use a mouse or trackpad its fine no lag). Also Premiere Pro CS5, playback is almost like watching footage in slow motion.

      Mac book pro (late 2013) has a lag when sculpting and rotating models in Zbrush, but only when using my Wacom-capture tablet (if I use a mouse or trackpad its fine no lag).
       Also Premiere Pro CS5 playback is almost like watching footage in slow motion, Premiere Pro is installed on the main drive but the footage is on an external drive connected with USB 2.
      I'm wondering if it is just a problem with the Mac USB drivers maybe not supporting USB 2 ? (Because I have also installed Window 7 on this same MacBookPro and tested the same software "Zbrush and Premiere Pro" And they both work perfectly on the Bootcamp Windows 7 install, and so its using the same hardware so it has to be the drivers right ?)
    Any help would be great, Thanks

  • I lost my bluetooth after installation of Maverick2. Can anyone help me please, i cannot use my magic mouse on my Mac Book Pro  retina???

    I lost my bluetooth after installation of Maverick2. Can anyone help me please, i cannot use my magic mouse on my Mac Book Pro  retina???

    There is a fix; I finally discovered how to clear the Windows 7 xx64 Device Manager's warning of a missing Bluetooth Peripheral device.
    Thinking Boot Camp 4.0 would correct thid, I installed it ititially today only to have the warning remain.
    The Bluetooth company called Broadcom (you notice the reference during the installation of Boot Camp) offers a BlueTooth "device finder" (my phraseology) that detects all BlueTooth devices in your Apple or PC but withing a Windows operating system; included are Windows 7 , Vista, XP and even 2000 operating systems.
    So download the 3 MB file, from Broadcom.com.  While your Bluetooth equipment is plugged in to the computer, run the program.  The program searches for any BlueTooth peripheral activated equipment and BlueTooth devices that makeup your MacBook Pro, or other Apple or a plain PC computer having a Windows operating system installed.  It then downloads the appropriate software required.
    The company's URL address:
    http://www.broadcom.com/support/bluetooth/update.php
    In my case, I ran the program, rebooted my MacBook Pro (in Windows 7 x64 and with the new Boot Camp 4.0 installed) and the missing BlueTooth peripheral device indication was eliminated.  It took 10 minutes to complete.
