Q: Repeated kernel panics in mid 2015 MBP

(I'm sorry but the last time I posted this I must have hit the 'solved button' but accident. It's not solved and so I understand from other threads that I should re-post my question. Please forgive me for being less than able on this sort of thing!)

 

Hi - Forgive the non tech language! I often charge up my relatively new MBP overnight. A few weeks ago I started to notice that it was often off when I opened the lid in the mornings - but the laptop is always warm, suggesting the shutdown had only recently occurred. On one occasion the fan was going crazy. (When this problem occurs I also find that power is used up relatively quickly. Right now for instance, I've been using it for 50 minutes and 20% has gone.) Closing and then reopening the lid (which sometimes had worked) failed and the only way of restarting the machine was to keep my finger on the power button. I've always submitted reports when prompted. And all my software is up to date. I back up regularly via time machine/time capsule and also with an portable external hard drive. If I look at Activity Monitor something called 'kernel_task' hogs memory and is always over 1 GB - at the moment, for instance, it's using 1.23 GB of memory - five times more than the next item.

 

I have uploaded the text of the panic report I received this morning ******** Apologies once again for the non tech speak. Thanks so much in advance!

 

Product info: MBP mid-2015 running El Capitan 10.11.5; 2.5 GHz Intel Core i7; 16 GB 1600 MHz DDR3; 500 GB SSD

    Hi - I tried that but it was rejected for having 'invalid characters' so I've had to post it to Dropbox in a public folder. I linked to it in my Question but I see it's been replaced by asterisks... Anyway, will try again - it's here https://dl.dropboxusercontent.com/u/6430903/Untitled.rtf

    A

    The problem may be caused by a bug in OS X, triggered by "Flash Player."

    If Flash is installed and you haven't already done so, please update to the latest version by opening the Flash Player pane in System Preferences and selecting the Updates tab.

    If Flash is already up to date, or if the update doesn't solve the problem, open the Safari preferences window and select the Security tab. Uncheck the box marked

              Allow Plug-ins

    See whether there's an improvement. If not, see below.

    B

    Please remove "DPS Audio Enhancer" and test.

    Any third-party software that doesn't install from the App Store or by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.

    Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.

    I never install system modifications myself, and except as stated in this comment, I don't know how to uninstall them. You'll have to do your own research to find that information.

    Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button. The uninstaller might also be accessed by clicking the Customize button, if there is one.

    Back up all data before making any changes.

    You will generally have to restart the computer in order to complete an uninstallation. Until you do that, there may be no effect, or unpredictable effects.

    If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.

    Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software.

    MMany thanks, LInc. A and B didn't work so I'm going to have to erase and reinstall the OS. Thanks for all your guidance and the learning points.
