Problem with auto after 10.11.4 brightness

After the upgrade to 10.11.4, my macbook pro retina auto light sensor has problems.

Have you tried the reset nvram and reset smc, still its not able to decrease or lighten the screen automatically.

Any help with calibration would be great.

If the problem is still there, try to start safe mode using your usual account.  Disconnect all devices except those necessary for the test. Shut down the computer and then put it up after a 10 second wait. Immediately after hearing the startup chime, hold down the SHIFT key and continue to hold it until the gray Apple icon and a progress bar appear. Startup is considerably slower than normal. This will reset some caches, forces a check for directory and disables all start-up and connection, among other things. When you restart normally, the initial restart may be slower than normal. If the system is operating normally, there may be 3rd party applications that pose a problem. Try to delete/disable the third-party applications after a reboot using the UN-Installer. For each disable/remove, you need to restart if you do them all at once.

Safe mode - on El Capitan

Start Mode without failure-El Capitan.

  • Problems with WiFi after put 10.11.2 up-to-date.

    Mid 2011 iMac.  Problems with WiFi after put 10.11.2 up-to-date.  No associated network.  Everything was fine before the update. All the pre 10.11.2 device works fine.  Anyone else having issues?  I have to disconnect and reconnect manually.  WiFi drops every 5 to 10 minutes.  Nothing has changed on the machine something of the update.

    Please do not comment on the age of the system.  Achieve a Mid 2011 arrived at a possible replacement point.  I have many other new Mac at home.  The Mid 2011 is spec'd with 16 GB of RAM, i7 and SSD.  It's always very fast.

    Thank you in advance for the answer...

    Hi Captainsniz

    There are a few things to try. Keep doing this until the problem disappears.

    First of all, if you have not already, shut down the computer completely, wait about 1 minute, then restart.

    Disconnect the wifi network either via system preferences, either by pressing the "Option" key and clicking on the wifi menu bar icon.

    Reset the DHCP lease by going to system preferences > network and show Advanced Options, and then click the button to "Renew the DHCP lease" TCP/IP tab.

    You can delete the wifi network of system preferences > network > network name... then close system preferences. Then reopen and add the network in.

    You can also restart your wifi router, it erases the old connections. Most of the routers you just turn off and wait a few minutes, then restart. You can also reset your ISP modem if you have a.

    Finally, you can try to reset the PRAM and SMC on your Mac. I'll get this info here on Apple Support KBs for your particular Mac.

    Be sure to back up your computer.

    Hope this helps, Greg

  • Problems with mail after switching to macOS Sierra

    Hey all

    After having recently upgraded to macOS Sierra, I am unable to read my mail.

    I get the following error every time I check on "Get Mail".

    There may be a problem with the mail server or the network. Check the account settings "*" or try again.

    The server returned the error: Mail could not connect to the server 'pop1.tribcsp.com' using SSL on the default ports. Verify that this server supports SSL and that your account settings are correct.

    What does this error message mean and how can I solve this problem.

    Thank you

    Hi Michael,

    I see your message that you get an error in the mail indicating that there is a problem with the mail server or the network.  To help get this problem resolved, I suggest that you follow the steps below:

    If mail refers to a problem with the mail server, or the network

    Mail will say that it is impossible to connect due to a problem with the mail server or the network. For example, the message may refer to a connection that has expired, or too many simultaneous connections:

    If you are connected to the Internet, but the connection has expired, your email provider might be affected by a discontinuance of service. Contact them or see their status Web page to ensure that their e-mail service is online. Examples of status pages:

    If the message indicates the number of simultaneous connections, too many of your devices is check your e-mail account at the same time. Quit Mail on one or more of your other devices.

    If you are still unable to send or receive e-mails

    1. Make sure that you have installed latest version of the Mac software updates, especially if the problem occurred immediately after the installation of a previous update.
    2. In OS X El Capitan or later version, you can see a status icon and the short error message in the upper right of the Mail window, under the search box. The message may indicate 'Network offline' or 'Connection failed', for example. Click the message to see more details on the issue.
    3. Check your connection to the Mail connection doctor. It might be able to say more on the issue.

    If you cannot send or receive e-mail on your Mac.

    Take care.

  • Problems with scrolling after update

    IM currently using the BlueJ ide and after updating to the new system / update (macOS Sierra) there is significant lag / jitter when scrolling. This problem only occurs when you use the scrolling with two fingers with the touch pad. When I use a mouse / or click the scroll bar on the side, it seems to go well. Not sure if there is a problem with BlueJ or the new OS. Would be very interested for some suggestions on how to fix this very annoying problem. (Using a Macbook pro 13, 2015).

    Thanks a lot to all the answers

    The obvious question would be if you see the problem of scrolling in Mac OS standard applications such as Mail, Notes and Safari.

    If this isn't the case, it is likely BlueJ.

    (Sorry for my bad English, it is not my native language)
    Hello, it's been several months I have a problem with Firefox auto-scroll
    Keep the pressure on the mouse wheel can slide in all directions of the web page, very useful for long pages as well as for pictures very high resolution.

    Stop for several version (from 40.0.0 I think but not sure), scrolling stops and / or is extremely slow and jerky, so that the page is not fully loaded. It's even more painful if we wait for a strong image on a slow website loading.

    I tested Firefox Safe mode and it doesn't change anything.
    Turning off graphics acceleration nor solves this defect.
    Test a new blank profile...
    Remove and reinstall Firefox...
    Namely, I have no problems automatic scroll on Internet Explorer or Chrome.

    As I visit the photo galleries large high resolution, is often sucks having to wait finishes loading before you drag on the page with the wheel in a hurry.
    I then let your knowledge to help determine the source of this defect.

  • Big problems with fonts after upgrade to Yosemite

    Hello

    I upgraded my macbook pro to Yosemite for more than six months and since then, I have serious problems with application of fonts in browsers and many software I use. I googled the problem over and over again and nothing seems to help.

    In general, these are the main symptoms of the problem with screenshots:

    1 system ads are gibberished, or better yet, appearing with something like that, instead of letters:

    2. bold letters does not at all (when I use gmail, for example) or leads to an illegible font change:

    3. hyperlinks symbols on Web sites or webmail applications simply appear as empty squares and there is no way of knowing what you click on.

    Bottom line: before turning to the last option and the resettlement of Yosemite, if someone could help, I'd be more than grateful.

    < image edited by host to remove the serial number >

    You probably have a lot of fonts installed garbage. Follow these steps to recover your Mac for only the fonts installed in OS X.

    (1) open the book fonts and choose restore fonts Standard menu. All third-party fonts will be moved out of the system and root of the fonts in the library files in a new folder next to each named (deleted) Fonts.

    2) click on the desktop so Finder is the name of the app next to the Apple logo in the upper left corner. Hold down the Option key and choose go > library. This will open your user account's library folder. Create a new empty folder on the desktop. Open the folder fonts in your user account. If there is something in it, move them to the new folder on the desktop.

    3) restart in Mode safe mode by rebooting and hold down the SHIFT key. When you reach the office (you need to log in Mode without failure), restart normally. Among other things, this erases all the cache files on the account of the user logged in Mode safe mode and resets the database of book of fonts for this account.

    (4) clear all remaining the system font cache files. Close all the running applications. From an administrator account, open the Terminal application and enter the following command. You can also copy and paste from here in the Terminal window:

    sudo atsutil databases - remove

    Terminal will then ask your admin password. When you type, it will not show anything, so make sure you enter it correctly.

    This command removes all the font cache files. To the system and the current connected to the user account. After you run the command, close Terminal and immediately restart your Mac.

    Now test. With only fonts available provided OS and all data policies implemented cache and other such parameters cleared and reset, fonts should appear correctly in the system.

    The convenience store said there is a problem with the driver, but I can't find a new driver through windows update, and HP does not either for my model. The device installed on my laptop is called high definition Audio Device. Can anyone help, if not, where can I download the drivers from. It is better to buy driver update software to help locate the right driver?
