MacBook Pro stops during games

• MacBook pro stops during boot, same drive boots imac

  My 2009 MB Pro has a 2 TB with (MacOS 10.11) inside drive. It suddenly started to stop a few seconds in the boot process. When I walk in target disk mode I can still boot my iMac using this same internal drive via firewire. I used it like that for a few weeks with zero problems.

  I ran each diagnostic that I can think on the drive, including the latest version of Techtool Pro, and the player with the flying colors each time.

  I suspect the problem was the MacBook Pro hardware, but it starts on another internal drive (with 10.6 on it) very well.

  Any idea what I can do here to get this drive of my MacBook Pro starting again?

  Reset the SMC and the NVRAM:

• MacBook Pro stops during sleep

  My MBP 15 "mid-2015 retina stop completely during sleep. Often when I get back to my MBP, I have to start from scratch because it stopped during sleep. There is no message in the log to indicate why it closed and no error messages or indications of kernel panic. Sometimes the power and battery and with or without the lid closed. Latest OS X with all updates applied.

  Reset the SMC (and NVRAM) does not help. Apple Diagnostics is no problem, and Genius Bar suggested I have first of all to make an OS X install excessive, then a clean install because they believe that it is a software problem. I tried to install too, and it made no difference. Pure install then, but I delayed, because it involves a lot of work in store again my work environment and data, it is not useless in current state - it's just a problem of waiting for the start up and then restore whatever, I was working on the last.

  Any advice?

  There is no message in the log to indicate why it closed.

  There could be.

  Wait until the Mac stops unexpectedly, and then check your system.log file to identify the numeric code associated with the stop. Read below.

  Locate the Console application - it is located in your utilities folder and looks like this

  

  You can find it by selecting utilities in the Finder go menu.

  Open the Console.

  If the list of newspapers on the left column is not already displayed, view journal list by selecting view list of newspapers on display menu of the Console.

  Locate system.log in the list, and then select it. Many date and time-stamped entries will appear, hundreds of them, and you need to find the relevant entries to your Mac problem.

  Do that type the word cause stop in the field filter on the top right of the Console window.

  Who will do all the log entries be hidden, except for entries that contain these words. There will be a numeric code associated with the entry of journal from «Cause of previous stop» What is this code?

• My Macbook pro stops unexpectedly when approximately 30% of load.

  Hello

  I have a Macbook Pro late 2011 2.8 GHz, 4 GB of Ram (I've already ordered a kit of 8 GB and waiting for her) running on OSX El Capitan and recently changed the battery. It worked fine for the first two weeks. It loads normally and work fine without fresh power. A week ago, he began to stop himself when he was about 30% remaining battery. Indication of battery level lights flashing a couple of times, everything as he had no more battery left and 3 of them would be on again. If I tried to turn it on, it would go up to a certain point and then close itself again. It wouldn't light up to accused. I've read that it could be due to heat problems, but this occurs even when the fans are very low and the macbook is cold. I read this reset THAT SMC can solve the problem that I did that and still nothing. Can someone help me please?

• MacBook Pro stops when the lid closes, loses the open tabs and background image...

  Hi all

  I recently had a new hard drive installed in my 2012 13-inch MacBook Pro. I am running El Capitan 10.11.2. Since then, my computer cuts automatically to the bottom when the lid is closed, losing all Web pages, and for some reason, some background, I've saved. (My browser is Mozilla Firefox and it prompts you to restore me the tabs lost, which he will).

  The led standby does not blink or light up when the computer is turned on, it will turn on only at startup. At startup, the login page is displayed, and after that I entered my password it takes about 15 to 25 seconds to load and open my account. What is going on?!

  Summary:

  Stop when the lid is closed,

  Loses the background image & open Web pages.

  Standby blinks only when starting,

  Time of loading extended after logging into my account.

  Any help would be greatly appreciated! Thanks a lot for reading.

• I'm on a macbook pro, and without knowing it, I turned to the vault of fire during a software update. The encryption process has begun. If I can't decipher, which will make my slow mac? or encryption is slow mac anyway?

  Hello

  I'm on macbook pro 13-inch (mid-2012), and without knowing it, I turned on the Arch of fire during a software update (El Capitan 10.11.5). The encryption process has started and if I don't want to read more, which will make my slow mac? or encryption is slow mac anyway?

  or at the end of the encryption process, my mac is slow?

  waiting for a quick response.

  Thank you

  I have a MacBook Air with active FileVault 2012. There is no significant difference in performance. Note, however, that there will be a performance impact until the original encryption is complete and that it doesn't have a way to stop it.

• MacBook pro starts the process but stop before midway lights

  HI -.

  My MacBook Pro starts the boot process but stops and stops before reaching the point to halfway. This can be the result of something that I did yesterday, I disabled my MacBook during a software update. I don't know what has been updated.  (I've left for a few hours and would not leave my computer on while I was out.)

  Is there something at home, I can do to fix this?

  Thank you!

  If you do not know what has been updated, nor do we. Could have been a critical system component. Try to start in Safe Mode and see if that clears up the problem. If this is not the case, start in Recovery Mode, select disk utility and make a disk first aid. If that doesn't work or you can't get into Recovery Mode, then try Internet Recovery Mode, while the Mac is connected to the Internet (press Command + Option + R) so it starts off Apple servers and reinstall OS X. If all goes well, you won't lose too much data.

• Audio has recently stopped working on macbook pro 2014, Win7 x 64

  Material: Retina Macbook Pro mid 2014-15 "2.8 GHz 16 GB of RAM

  Software: Mac OS + installed bootcamp Windows 7 business N SP1 64-bit with latest updates attached to the field

  Audio worked absolutely the facility for a year or two. Just recently the speakers and headphone stopped working and SPDIF red light of the headset jack is now constantly lit (did not use to be informed in all). Maybe happened as a side effect of windows update, update of apple or software update or demand of the NVIDIA driver installation.

  What audio drivers should I have installed Bootcamp software support for MBP mid 2014? Real audio hardware is present on this MBP - Apple card is vague on this point?

  When scanning for hardware changes in Device Manager the same driver is always automatically reinstalled. There is no option to delete this. The driver update has no effect. The device is shown as working properly. There is no errors and there are devices of reading for the speakers, headphones and SPDIF, but no audio exited actually.

  • High definition audio
  • Manufacturer Microsoft
  • Location 0 (internal high definition Audio Bus)
  • version 6.1.7601.17514
  • day 11-19-2010

  There was also a Microsoft device system speaker (don't download reinstalled during the analysis of new equipment) and nvidia audio drivers (for audio output HDMI).

  An additional symptom - connect headset does not show the helmet as playback device as a playback device connected as I expect.

  Is it possible the Bootcamp software support has failed to reinstall the audio drivers correctly? Can I get a feedback or a software Bootcamp Support log to see what's happening?

  A Windows somehow got locked in a SPDIF output? This cannot be a purely material error as MacOS still work very well?

  Other measures to diagnose this problem?

  A few steps I've tried without success:

  • Check all volume and mix parameters
  • Roll back these recent software installations
  • Watching installed the drivers in Device Manager - all audio devices are shown as working properly analyze, because material changes do not find any additional sound hardware to configure. Update driver drivers online research is not to find an updated driver.
  • Using an another USB audio device - this device works great
  • Reboot under Macos - built in speakers very well work
  • Restart in SafeMode the Windows - audio device does not appear to be installed (maybe the driver no is not supported in safe mode).
  • Reset the NVRAM (restart with option commmand PR)
  • Reset the controller of the SCM
  • Run the restore of the system - restore points fail to restore with the exception of a few of the latter that does not solve the problem
  • Uninstalling all audio drivers and re-run bootcamp support software setup.exe (the older version of download 5.1.5640 which seems to be the only one who supports my hardware/windows 7 x 64 combo)
  • Back the NVIDIA driver to the version provided with the support of bootcamp software
  • Intel chipset installers running provided with the support of bootcamp software
  • Assistant Configuration boot camp running on Mac OS to get the latest drivers - fails because does not support my combination of material and win7 x 64 as documented on Apple support pages
  • Not running Apple Software update - no update is available for all drivers.
  • Don't run Windows update - no update is available for all drivers

  If the red light goes out in OS x but not in Windows, it seems to be the State of the combined analogue/digital port stored in the Windows registry. On W7 on a 2013 rMBP (he has the card nVidia 750 m), this is what you should see your Audio devices.
