Failure of Bluetooth subsystem after put 10.11.2 updated

Thanks in advance for any help!  After the upgrade of 10.11.1 to 10.11.2, my bluetooth subsystem seems to have disappeared.  Bluetooth no longer appears in system preferences and information system now lists "No Information found" under bluetooth.  I did a reset of memory NVRAM and SCM, as well as the boot in safe mode and also remove com.apple.bluetooth.plist.  Nothing did.  My machine is a Mid 2015 15 "retina, i7 2.8 GHz with Radeon graphics option.  Any help would be appreciated!

Please let me know if I can provide any useful information.

Reset the SMC (again) - that almost always corrects missing bluetooth problems.

FWIW, Bluetooth is available on my system after updating to OS X 10.11.2

  • IPhone SE lag after put 9.3.2 update

    Hi all!

    2 months ago I bought a new iPhone t-mobile SE.

    After the 9.3.2 update, I noticed accused for example: on the home screen, during the games (BBTAN, Jetpack Joyride etc.) when the phone is automatically set the brightness of the screen.

    (I noticed this when I went from the shadows in the light of the Sun)

    Is there anyone who has noticed this problem... or... What can I do with this...? !

    Thank you

    Best regards, David

  • Messages app does not split view after put 10.11.2 updated

    My apologies if this is covered elsewhere, but it is a problem that arises for me after I've updated from El Capitan version 10.11.1 version 10.11.2

    Following the update of the system, the application messages appears more correctly in split view.  I can put messages and a second application in mode split as normal, but the message window is not reduced to fit in his half of the screen (the second app sits on her side of the screen and resizes properly).   The electronic app continues to fill the entire screen, with the second application instead 'window' is blocking half of the messages window when the second application is active, or with the second window app entirely hidden by the messages app when messages is enabled.  Messages worked normally in split in 10.11.1, it has started having this problem then I upgraded to 10.11.2 and it does appear that the messages app that does this.

  • iPhone 6 less sensitive after put 9.3.3 update

    I have an iPhone 6 16 GB with operating system 9.3.4. After 9.3.3 update my phone started to slow down and block. That, the phone at any time. When the phone hangs up, I can't get to restart by the locking of the two buttons and the home method. So far, I've done the following: reset the cache, reset the system settings, resetting the phone, disable javascript, may reduce transparency, reduce motion blur, disable health settings and deleted about 5 GB of music storage. What is the next logical step? The phone is less than 2 years.

    I assume you mean that you have improved your iPhone 6 of 9.3.3 to 9.3.4, not the other way around as you posted... correct?

    If Yes, then based on what you have tried so far, I would say that you take a go-Genius Bar at your local Apple store to make them take a look.

  • Battery drains after put 10.0.2 update

    Since the update of my iPhone last night (10/01/16) my battery drains very quickly. Do not have this problem before the update.  All the patches?

    Greetings Willie9100,

    Thank you for using communities of Apple Support.

    I see that since the update your iPhone last night 10.0.2, your battery empty very quickly. You don't have this problem before the update. I can imagine trying to stop draining your battery. I'm happy to help you with this.

    Please take a look to maximize the life of the battery and battery life and display battery usage information and to see what proportion of your battery used by each application, specifically, this section:

    View the battery information

    iOS 9 is designed to be the most efficient battery iOS ever. And it gives more specific ways to manage your device's battery life, because you can see the proportion of your battery used by each application (unless the unit is being charged). To view your usage, go to settings > battery.

    There are messages that you can see below the applications you use:

    Background activity. This indicates that the battery has been used by the application while he was in the background - in other words, while you were using another application.

    • To improve the battery life, you can disable the feature that allows applications to background refresh. Go to settings > general > background App refresh and turn the switch to Off.
    • If the Mail app lists substantive activities, you can choose to manually recover data or increase the recovery interval. Go to settings > Mail, Contacts, calendar > retrieve new data.

    Location and the location of the background. This indicates that the app uses location-based services.

    • You can optimize your battery life by disabling the location Services for the tour app in settings > privacy > location Services.
    • In location Services, you can see each app listed with his permission setting. Applications having recently used location-based services have an indicator next to the on/off switch.

    Home & lock screen. This indicates that the home screen or the lock screen has been posted on your device. For example, the display was awakened by pressing the Home button or by a notification.

    • If an application frequently wake up your display with notifications, you can disable push notifications for the app in settings > Notifications. Push App and set allow Notifications to Off.

    No cell phone coverage and low Signal. This means that either you are in a poor cellular coverage area and your iOS device is looking for a better signal or that you used your device in conditions of weak signal, which is reached in your battery life.

    • You can optimize your battery life by turning on airplane mode. Drag up to open Control Center and press airplane mode icon. Note that you can not make or receive calls in flight mode.

    Let us know if that helps.

    Have a wonderful day!

  • IPhone 4S brick after put 9.3.5 updated

    I have an iPhone 4S which recently prompted me to download and install the latest 9.3.5 update.  At halfway through the process stopped updating, and now the phone keeps stuck in mode 'connect to iTunes '.

    I tried restore and update regularly through iTunes as well, and the restore process ends with an error (29). Error message is:

    The iPhone "iPhone" could not be restored. An unknown error occurred (29).

    1. my phone is a factory unlocked phone, so no Jailbreak etc has never been done

    2. I was able to update my phone until 9.3.4 with no problems before this

    3. I changed the usb cords, computers etc.

    4. my iTunes is the more up-to-date version.

    Has anyone else seen this problem as well on the other iPhone 4S? Any ideas on how to solve this problem?

    just tried to do the same thing on my 4S - bricked with the request to connect to iTunes - which did not help if - error 29 (or 39?) ensures the Outlander when I have that either opt to choose to update or restore

  • Sculpture of filter automation problems after put 10.2.1 update?

    Since I've updated, I can't find the filter cutoff or controls resonance in the list of options selectable automation more. I have a track I worked on where I got "Morphpnt 0 filter Cutoff" control the filter cut on the sculpture, but now, even in the same project, that option is not available to select in the list of automation. It seems to me that the option is missing from the list since the update, but maybe I'm wrong, and I'm looking in the wrong place. Any help would be appreciated.

    In virtue of which the Automation subcategory have this setting allows to reside?

    I remember a particular where my question that you're right, I can't locate less 10.2... but I think it's a bug, error or perhaps a change of design for reasons unclear.

    However, there is a clue...

    In the smart controls... When you go to the Non automatable section... (this is why it seems to have been deleted or excluded from the list of normal Automation) it lists filter Cutoff for the Sculpture, but you can select it and then save automation using the assigned smart command...

    Someone at - he had problems with Mac Mail since the 10.11.2 recent update? On my laptop it seems to take a large number of cycles for all CPU. It seems like the Exchange server update that they broke something OR did Mail check something too frequently. Write emails, reading emails, looking for emails, going through lists of contacts for email address, etc. are extremely slow, taking sometimes a minute or more.
