MacBook Pro wifi hardware not installed after update of El Capitan

Hello

I connected my macbook this morning to find that I had a gray wifi symbol with an x through it saying ' wifi: no hardware installed '. I'm taking in the Apple Store to be looked at in a few days, but only I was wondering if anyone in this community has experienced a similar issue that has an easy solution so that I can return to the top and run. It worked all fine until this morning.

Ive updated to El Capitan - 10.11.1

I have a Macbook Pro 13 inch retina end 2012

Thanks in advance

This means that the two Wi - Fi drivers are damaged or that your wireless card has stopped working.

A good way to find out what the problem is to start up in OS X Recovery in now pressed the command keys so much R during start up your Mac to the top. Once your Mac is turned on, look at the Wi - Fi icon in the upper right and see if you can choose any Wi - Fi network. If so, reinstall OS X.

However, if you can not choose any network, it is probably a hardware problem, so you have to take your Mac to an Apple Retail Store or dealer to get the Wi - Fi card replaced.

  • MacBook Pro keeps freezing and timing after update to El Captain 10.11.15

    I have a MacBook Pro, which was previously executed on SCF 10.11.14 2013. I began to see problems before my laptop even turned on! When it is restarted after installation, I got about 60% of the way down the front loading apple bar it has completely stopped. I waited quite awhile (maybe 20 minutes) but no progress on the charge. I did a reboot hard twice before he finally finished (sidenote: both times I restarted, instead of starting at the beginning of the load bar as it should, the load bar would start in the place of 60% that he is stopped at the first time).

    It finally comes and I had to open iTunes, Photoshop and Safari so it was very laggy. After working on my laptop for five minutes, the song that I had started doing these breaks, and Photoshop as well froze upwards. I tried to go on Safari, and that's where the beachball replaced my mouse arrow. I tried to use my MB with the only window open (photoshop), but even force weren't no longer works. It just seems to be freezing for longer periods of time.

    I ended up doing a hard reboot once again and only with the help of Safari, but this does not work. Hard restart once again tried only using Photoshop and encountered the same problem. This last time, I have Photoshop open, but for some reason, the tools are not answer at all. For example, when you use the Paintbrush tool, you will see a circle in the placement of the classic mouse arrow when you are in the photoshop window. Well, the arrow of the mouse remained and everything I clicked on, as well as two fingers/output action zoom did nothing. Nothing does in Photoshop anyway.

    Could someone please, please help me? I'm a photographer and I have a project due to my clients in the morning, and I can't afford this issue right now. I write this on my MB Air, which runs on CBS 10.11.13. I'm afraid to try an install of update on this one!

    If nothing can help, can someone tell me how easy and on an empty stomach to downgrade to the previous version of El captain? Thanks a bunch!

    There is no easy way to downgrade. He must erase the drive and then reinstall OS X. First, you need a good backup. Or you can try the following:

    Try these in order to test your system after each see if it is back to normal:

    1. a. reset the PRAM and NVRAM on your Mac.

    b. Macs with Intel processors: reset of the controller (SMC) system management

    2. restart the computer in Safe Mode, and then restart again, normally. If this does not help, then:

    Boot to HD recovery: restart the computer and after the buzzer, press on and press and hold the

    Command and R keys until that Menu Utility screen appears.

    3 repair the hard disk and permissions: restart the computer and after the buzzer, press on and hold down the command and R until the Menu Utility screen opens.

    When the Utility menu, select disk utility, and then press the continue button. After loading disk utility select it

    indented (in general, Macintosh HD) entry of the list to one side.  Click first aid button in the toolbar. Wait for the operation

    is over, then quit disk utility and return in the Utility Menu.

    4 download and install updated Combo OS X El Capitan 10.11.5.

    5 reinstalling OS x: reboot of HD recovery Select reinstall OS X in the Utility Menu and click on the continue button.

  • Adobe Acrobat Pro DC does not print after update

    Hello

    I have a client who is tried Acrobat Pro DC, before buying and recently installed an update of Adobe. After that, she can no longer print to Acrobat Pro DC on a network print server printer. She clicks print in the print applet and nothing happens. It is not the coil in AcroPro, is not be wrapped up in the service of the coil, and it prints on the printer. No errors come at all. Already have tried all solutions in print troubleshoot PDF in Adobe Acrobat and Reader and none of them were working a repair to AcroPro and temporarily disable the anti-virus. Other applications, including the AcroReader DC can print fine on the printers on the print server. AcroPro DC will print on a local printer on a network running the same driver as the print server. Operating system is Windows 10 is 64-bit, OS Server R2 Print Server 2012. Solutions or insight would be helpful.

    Thank you

    Hi [email protected] ,

    Please follow this thread to reset the Acrobat preferences:- How to reset preference settings in format Acrobat.

    Would please check after you disable you the safe_mode in Acrobat program ask: -.

    Acrobat > edit > Preferences > (enhanced) protection > uncheck "Enable Mode protected at startup" & "Enable Enhanced security."

    Then in this same option, on the bottom there is an option to "Add host" where you can put the name of the server & then OK.

    Relaunch the application and check for the same thing.

    If the problem persists, please check with the different user account to reproduce the problem.

  • T400s "battery not installed" after updating to Bios (1.20)

    Hey,.

    I have a problem with my T400s. It is a month and he now asked me to update the system software. I did it and it installed a lot of new drivers etc Inc. a Bios Update. (1.20)

    The problem is now, who can't see the condition of the battery. (The battery icon remains Gray and says "battery not installed")

    The work of computers very well (AFAIK) both on battery as power.

    I checked the thinkvantage Toolbox diagnostics and there I can see the State of the battery (for example, discharge, 48%).

    The latest versions of thinkpad power manager and driver ThinkPad power manager are installed.

    I tried restarting the computer and remove the battery for a while, it does not work...

    Someone at - it an idea?

    Have you tried to reinstall thinkvantage Power Manager?

  • External screen does not work after update of El Capitan

    Hi all

    I hope someone can help out me with this. I have a MBP 2011 (i7, 4 GB ram, 330 M) and since I've updated to El Capitan (now 10.11.2) my external screen no longer works. I use a HDMI Cable MiniPort who worked before the upgrade. I am trying to connect to a 720 p TV and tried to connect it to my 28 '' ASUS monitor 1080 p that I normally use for my Windows desktop. None worked. My MacBook display blinks for a while when I connect it and then nothing. I was not able to connect it to my projector via VGA USB adapter until I've found the last update on the Web site of the adapter, then at least the display has been resolved. I tried the 'View to detect' button in the preferences system, no luck.

    I had the same problems. I installed El Capitan in MacBook Air early 2015. My external monitor is Dell P2314H. After installation, the MacBook Air is no longer detected the monitor, and the monitor does not save any video input to the computer.

    I chatted with Apple Support, but they don't give me satisfactory answers.

    Then I came across this answer on another thread of discussion the similar question:

    Re: El Capitan does not detect my external display

    And the solution that works for me is proving to be as simple as changing the cable. So I stopped using official mini Apple displayport to HDMI/DisplayPort/DVI connector. Instead now I use a cable (mini displayport to displayport in my Dell of MacBook Air) I bought locally (I live in Jakarta, Indonesia). It works like magic.

    I hope this helps you.

  • Toshiba EXCITE Pro - WiFi. Authentication failed after update

    Hello.

    Just got this tablet.
    Everything seemed ok by updating to the latest version (because first of all to solve the problems of heat).

    After the update * I lost my WIfi connection. Failed authentication * (has not changed anything - linked - update ok 1 minute before the last update).

    After that I started to not test, Wps, Wifi etc etc security connection
    * Finally, at a random time (and with the original settings) I logged in *. After that I closed the Tablet the same problem occurred.

    After doing the same things again once I finally logged and this time it seems to be ok, even though I stopped the tablet.

    However, it's frustrating.
    Maybe you have to address this issue?
    I have seen and others return this tablet after having this problem.

    It is not a hardware problem since its correct operation before the update.
    Of course tried factory reset twice.

    Hope, I don't have this problem again, * but I inform in the hope that fix you this in a future update.*

    Hello

    Go to your wifi settings - forget your network - connect again with your code

    Normally after that he has to work again.

  • 8.1 will not install after updating

    My computer laptop (Acer Aspire V5-122P-0643) was running bad so I ran a refresh on it.

    After the update, I installed all the updates important and then tried to reinstall 8.1 but when I press the tile into the store it dose literally nothing no nothing just the error. I can't 'trust' my laptop so I spent account.live.com/trustdevice and entered everything, including the code sent by text, but nothing helped. Another problem is that if I try to install an app on the store it is stuck on standby.

    I think that all these things are related, but do not have a solution or all tracks.

    S ' ensure that you apply the latest updates before upgrading.

    -Try to switch to a wired connection if you download over Wi - Fi

    Disable/uninstall no matter what third-party Antivirus, you may have installed before the update.

    -Do a clean boot.

  • Battery and Wifi info not displayed after updating IOS 10

    After upgrading to IOS 10 I have more information at the top of my home screen line. He comes to the line with WiFi, battery, and other info. I see it if I open an application, only some however. This status being lost, it is difficult to look at the life of the battery.

    How do I turn it back on?

    If it cannot be enabled by the user, then Apple needs to bring him back.

    David

    Hello! You can activate the in your settings. Go to battery and select on the percentage. The other options that are displayed on this bar, you can also turn on in general settings. Make sure that the WIFI is enabled in the settings. I had this happen before. After trying your settings, if you still do not see the bar with all the status restart the device. If it still does not work, you can try to recover the device on iTunes. The last resort would be to call the Apple support. I'll try to fix it in the settings that the lines may be busy.

    Last night, updated my (laptop) windows and when turn it on this morning the wifi no longer works. Ive tried many things; Uninstalling the drivers, reinstall, reset the default bios settings, back up the updated driver, updating the computer, etc.. I have no idea what to do here. Before updating the system, I got windows 8.1 but now she's back to windows 8 after the update. Help, please.

  • Microsoft Office 365 does not work after update of El Capitan 10.11.4 March 27

    I've upgraded to El Capitan 10.11.4 March 27 and my Microsoft Office 365, specifically the word & excel stopped working properly. Files can be opened, but when you save the new content, and then close the document, it does not record properly (and no backup or temporary file cannot be found). Once opened again, they eventually return to the saved before the update version. Thus losing the latest added to the document after the update.

    If anyone has experienced this or can help, I'd appreciate it. This is my first mac and I thought it would be much easier to use than a PC, but I'm not sure I can take this abuse much more time

    You can also report the issue in the Microsoft support forum. Note that Office 365 indicates only that you purchased Office in the subscription, but it does not indicate what version of Office you are using. The following link will allow you to choose the version during the validation of the issue: http://answers.microsoft.com/en-us/mac
