Macbook Pro Late 2011 not recognising Ethernet Adapter after upgrade to Mavericks

Hi everyone
I updated from Mountain Lion to Mavericks (I deleted all the files and made a fresh install), but since then my Ethernet adapter stoped working! when i see the system report i find this information
i've tried reseting PRAM and others and didn't result in anything
when i go Networking Settings i don't find anything related to Ethernet Adapter

Ok. Thought I would check just in case.
We could try to remove the System Configuration which includes lots of setting files that relate to networking.
If you want to do this then go to Macintosh HD>Library>Preferences and there will be a folder at the bottom called System Configuration. If you delete this, (type in your password to confirm your sure you know what you're doing) and then you need to restart the machine.
The reason for the restart is that when your machine starts back up it looks for the system configuration and because it isn't in folder we just deleted it from, your Mac creates a new copy of it.
Give this a go and let me know.

    Macbook Pro late 2011 not powering on. The charger shows a blinking dim orange/green light. I have tried pressing the small button on the side of the macbook pro to check the battery, but no lights show up.

    Hey Angelo_here,
    I'd run through these steps:
    If your computer won't turn on, try each of these steps:
    Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
    If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
    Note: See Apple Portables: Troubleshooting MagSafe adapters for further troubleshooting with MagSafe adapters.
    Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
    If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.

  • Help! MacBook Pro Late 2011 Not Charging

    My MacBook Pro Late 2011 is Not Charging. I have tried plugging it into multiple outlets and none have succeeded. He is a screenshot of my System Information>Power: http://grab.by/tkOM. I have no clue what happened. Last night we had a massive storm, but I don't believe there was any thunder or lightning. Whenever I plug the adapter into an outlet, the battery usage in the top right hand corner shows the "plugged in" icon, then it shows the "charging" icon. Then it just goes blank and back to normal. I have tried to restart it and do the SMC or whatever, but nothing seems to work. I have had this charger for a little bit over 1 year. Thanks in advance!

  • MacBook Pro late 2011 not switching to ATI graphics when running off mains power.

    Hi there.
    My MacBook Pro late 2011 doesn't appear to be switching to ATI graphics when running off mains power. It always seems to stay on the Intel adapter instead. I've checked the option in the energy saver settings and it's ticked to "Automatically switch..." and when I untick this box, it switches to ATI and stays that way even when running on battery (as expected). Either way it will not switch to ATI graphics when plugged into mains unless forced to in this way.
    Any one else seen this? Very frustrating when trying to run an external monitor with the Intel adapter!
    Thanks in advance.
    Dan

    "As a last resort I opened the bottom cover and disconnected the battery power plug (MagSafe adapter also disconnected)."
    After everything was disconnected did you press the power button and walk away for 5 minutes? Try that, just had one restart after waiting for that long.

  • Macbook pro late 2011 Not installing Mountain Lion

    How do you boot from mountain lion installaion Because now it's just opening in lion rather than on startup?

  • Photoshop CC 2014 extremely slow after fresh intallation on MacBook Pro Late 2011, i7   8 GB RAM, Photoshop CS 5.1 performance OK

    Hi there,
    I just installed Adobe Photoshop CC 2014 on my MacBook Pro Late 2011 with 8 GB RAM after already having installed CS 5.1 on my MacBook.
    So I have both installed at the same time.
    But: CS 5.1 is much faster! The first time opening CC 2014 was really shocking, because it was so laggy and still is, and I don't know why this is.
    I didn't do any weird performance settings, neither did I change anything else. I open a document in CC 2014 and it takes nearly double the time
    compared to opening the same document in CS 5.1.
    And with CS 5.1 running the app Memory Clean tells me that i have 1.5 GB of free memory, with CC 2014 running my memory is completely in use.
    Are there any tipps/tricks/issues with having both installed at the same time? Am I missing something that is leading to that specific performance
    issue?
    I would be glad if someone could help me, because otherwise I have to say that upgrading to CC 2014 and buying the CC license for one year
    didn't turn out to be a good thing.
    Thanks!

    Nothing here?
    The MacBook now has 16 GB RAM, but not much change. Photoshop CS 5.1 performance is great after splitting the PSD into 3 different ones, Photoshop CC 2014 still much slower.
    Does anyone experience the same problems, especially with many groups / layers / smart objects?
    And is it possible to get back the money for purchasing the yearly CC license when I'm not satisfied with the product?
    Thank you.

  • Macbook Pro Late 2011 Grey screen

    Hi pals,
    I have a Macbook Pro Late 2011 since 2012. I've upgraded it to Yosemite, thing that I've to do from scratch because it worked very slow, but that's not the deal here.
    The other day I started it, and it simply didn't do it. I've tried everything, like Unique user mode, safe mode, starting from dvd, reseting PMU-PRAM-NVRAM, changing hard disk, changing RAM,... everything I've found in the internet.
    Only one thing worked once, and I say once, because it only worked once... I switch the HD and I used an USB to install Yosemite from scratch. It worked but when I reseted it, it never came alive again... That time, I used Disk Utility on Yosemite to format the original hard disk (700GB 7200rpm), and I recovered my personal data.
    Now, when I try to start it from USB to install or from HD it never works. It shows the progress bar till 1/3 and then the screen becomes grey, the CPU heats and the fans start to spin like crazy. Sometimes it turns off, sometimes it doesn't and I have to do it.
    Any help will be welcome, thank you .

    The colored lines  seem like it's a hardware graphics problem, likely brought on by the EFI firmware update that's been going around lately that exposed problems your hardware had you didn't know about.
    Your  going to have to bring this problem to Apple, I hope you have AppleCare because it's looking like a replacement logicboard and they are not cheap.
    You can try exhausting the remedies in my User Tip, but those mostly deal with issues from the gray screen onwards, the colored lines represent a firmware issue and Apple doesn't release the newest versions online for self reinstall until they have proven themselves.
    If your worried about sensitive data, you can order a tool kit from OtherWorld Computing, open the machine and remove the hard drive and use a SATA to USB connector to another Mac to remove data and scrub free space in Disk Utility.

  • Osx 10.8.4 does not run macbook pro late 2011

    does any have issues after installing osx 10.8.4???  because i have an issue after i update my macbook pro late 2011 ,it doesn't start and only stay on the mac logo and appears the pointer i restarted many times and does not work the only option i had is  to reinstall the osx 10.8.3. can anybody help me with this issue??  thank you.

    Reinstalling Lion/Mountain 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/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

    So what you want is to be able to boot from OS X and retrieve your files
    Create a data recovery/undelete external boot drive
    Of course if it's not booting up, it's easier to fix in place
    ..Step by Step to fix your Mac
    https://discussions.apple.com/community/notebooks/macbook_pro?view=documents#/
    ...so I am trying to boot from a USB recovery drive but when I select it nothing happens it just goes to the restore options
    "Recovery HD" is a partition on your boot drive which you option or commnad r key held at boot time to get into and then repair the Macintish HD partition.
    If you have this on a external USB thumb drive, then that's all it is, no OS X, programs or files.
    If your talking a USB external drive, it has to be a OS X bootable clone made with Carbon Copy Cloner or SuperDuper and the option key held at boot time gives you that boot option.
    Most commonly used backup methods
    So what your saying is you have a external clone and by holding the option key down at boot all you get is it directly going to Recovery HD?
    There is no Startup Manager option to choose what to boot from?
    This could mean Apple changed something, or your external bootable clone isn't one, or the wrong software used so it's not being recognized by Startup Manager as a bootable option.
    What did you use to make the external OS X USB bootable drive?

  • My japanese macbook pro (late 2011) physical keyboard does not match with the on screen japanese keyboard in windows 8.1 so does caps lock

    I am using windows 8.1 pro on my Japanese macbook pro (Late 2011) and enabled japanese language but the problem is that when i press caps lock (lower left corner) it changes the input method from english to japanese. I checked my on screen keyboard (OSK) in windows and its different from my physical keyboard i.e. keys are different on my physical keyboard compared to OSK. Can anyone help me?
    Thanks

    Can I suggest the following articles, which are worth reviewing?
    Boot Camp: About keyboards and key assignment for Microsoft Windows - Apple Support
    Boot Camp: Apple Wireless Keyboard keyboard mapping in Windows - Apple Support

    Windows does require language packs to be installed, if you want the physical keyboard to match the on-screen keyboard.

  • Graphic problem in 13'' macbook pro late 2011

    I have problem with my 13'' i7 macbook pro (late 2011) . for instance when i swipe up/down with 4 fingers, my apps or docs minimize So logy and slowly as well as when i want full screen my browser or other application, it do it very bad with some vibration and i dont know what do i have to do?
    is this problem for my graphic card or is for Lion ios?
    as the matter of fact , i bough this mac 2 months ago.
    Im wondering if someone can help me in this regard!

    Since it is less than a year old call AppleCare: 800-SOS-APPL (in the US).
    Have your Mac's serial number ready: http://support.apple.com/kb/HT1349
    After you wait on hold for a very long time they ask you some frustratingly basic questions like is it charged and did you spill water on it etc., they will talk you through some basic troubleshooting such as an SMC reset. In the end they will offer to schedule an appointment at a Genius Bar where they will fix whatever is wrong. It won't cost you anything (unless you spilled water on it etc).
    You can do all this yourself:
    SMC reset:
    Resetting the SMC on portables with a battery you should not remove on your own
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer.
    Genius Bar Reservations:
    http://www.apple.com/retail/geniusbar/
    You can test the hardware yourself also, if it reports something wrong tell them what it is.
