My configuration :

MacOS Sierra 10.12.3 (16D32)
MacBook Pro (Retina, 15', late 2013),
Model: MacBookPro11,2
2 GHz Intel Core i7 (i7-4750HQ) CPU: 4-core
. BANK 0/DIMM0
.. 4 GB DDR3 1600 MHz ok
. BANK 1/DIMM0
.. 4 GB DDR3 1600 MHz ok
Bluetooth: Handoff/Airdrop2
Wireless: 802.11 a/b/g/n/ac

Step to reproduce the crash :

  1. turn wifi on (sometimes crashes happened just after deactivating wifi and when the systems restarted the wifi card had disappeared, icon marked with a cross and popup saying "no wifi hardware detected")
  2. disconnect any ethernet thunderbolt cable or deactivate ethernet connexion
  3. simply use the computer for instance navigating with safari or chrome or wait a little doing nothing (less than 2 minutes now, but it used to be hours before the problem occurs)
  4. Boom ! Black screen, fans and keyboards back lights increase activity for a few seconds and then the computer just turns off completely

Noticeable informations :

  • bluetooth can be on or off, it doesn't matter or affect the crash behavior even if sometimes when I turn on the computer after a crash bluetooth can be activated or deactivated when it was in the opposite state before the crash,
  • no crashes occur when connected to internet with both wifi and ethernet or just through the ethernet port only. The problem is only when the wifi is on.
  • no crashes when in the mac is started in safe mode and with only wifi on
  • the issue started after updating to sierra os x and prior that date I had very few crashes in years (almost none). Unfortunately my time machine copies before migrating to sierra have been overwritten with post sierra's copies

I have tried several solutions but the problem remains. Here is a list of the opérations I went through so far with absolutely zero success :

  • Changing Mac OS X Wireless Card Country Code as explained here
  • removing all wifi preferences and all extensions, LaunchAgents, LaunchDeamons, Internet pluggins, etc. (both in /Libbrary/, ~/Library/, /System/Library, etc.)
  • removing all my applications that could mess up with the system (brew, ports, cleaner, magicPrefs, Citrix, antivirus, etc.) and cleaned all their remaining files (such as .plist files, etc.)
  • updating to os x sierra with the utilities of the recovery mode
  • bootable usb key, hard drive format, os x sierra clean installation and personal data recovery with time machine
  • and of course I have tried contacting the apple support (feedback/bug report messages, phone calls and several visits to the so called genius bar where all hardware tests showed nothing wrong (their conclusion : as it works fine in safe mode, it might be a software issue but they don't know where and why turning wifi on is triggering the crashes). My conviction : it is a faulty sierra wifi card driver responsible of the crashes as I always get com.apple.driver.AirPort.Brcm4360.0 crash logs after each single unwanted shutdown and few times accompanied with a com.apple.iokit.IO80211Family crash log (CCIOReporter log file).

I think all is said about my issue. And I will also provide a crash report (pretty messy) or an etreCheck reports (clearer) but both didn't give usable information. I hope my approach can help some of you solving similar issues and also that some can help me find a solution.

  • I reported the bug through the apple bug report and gave them a thorough analyse with the terminal command "sudo sysdiagnose -t" The answer I received is pretty puzzling from a company that own the material, the operating system and all the proprietary softwares on my computer. Basically, it is a known issue/under investigation. And I must check the release notes for changes affecting this issue. So I tried the beta program and installed the latest 10.12.4Beta7 but it also crashes every 5 min or less :(

    Have you tried downgrading to El Cap? I have many clients (including myself) who have solved a number of Sierra issues by going back to 10.11. If the problem persists there, then it's most likely hardware. Also, you may wish to try running Apple Hardware Test (AHT) to verify that the Airport card is good. Hold the D key while booting from a powered off state with the AC adapter connected.

  • Thanks @Allan for the reply ! Yes, I have tried El Cap and it didn't crash my MacBook. But maybe I didn't wait enough time because unfortunately all my old Time Machine backups were overwritten and I cannot import the data from the ones made with Sierra, that's why I had to resume to the new OS. Plus the AHT didn't find any issue. I took my computer to an apple certified repair and their deep hardware tests indicate a failing mother board and they said it might be a messy EFI update. So 2 options there : change the mother board or wait for a new EFI.

  • If you had a "messy" EFI update, you likely wouldn't be able to boot your Mac at all. If your logic board was failing, it would be picked up by AHT. Here's what you can do: go get an external drive like the WD Passport and install El Cap to it. Boot using the Opt key to select the external drive. If all works, then you know proof positive it's not your logic board.

  • Hi, The apple support after telling me the issue will be corrected by an EFI update, changed the recommandation and they asked me to change the material as the issue should have been resolved by previous updates. So I have changed the logic board and it is working perfectly so far :) Thanks again for the replies !

What helped me:

  • Using OS X Mavericks (default OS for my laptop, didn't have a chance to use Sierra/ElCapitan)
  • Using any usb wifi adapter;
  • Using native wifi but power adapter is connected
  • Using native wifi on battery but it should be charged > 45%

What didn't help:

  • OS reinstall (with/without disk formatting)
  • Remove wifi, airport etc config files
  • Reset SMC
  • Reset NVRAM
  • Look for updates (no updates available)

What I did else:

  • Launched Apple Hardware test (OK)
  • Launched some apple benchmarks (Geekbench 4, Blackmagic Disk speed test) (all OK)
  • Launched Coconut Battery (got 7193 mAh, designed 8440 mAh)

Other problems I found:

  • Can't turn the mac on (or wake it up) when the battery is low than 40%. But if I don't shut it down or hibernate it works down to 0%

I have no proofs but I think the problem is in the combination of soft wifi and battery status.

Had the same problem. Remove from user library, from folder preferences, the apple internetconfig files. Examples: com.apple.internetconfigpriv.plist com.apple.internetconnect.plist

(And any other you could find)

In addition you could remove the preferences for airport too:

com.apple.airport.preferences.plist

Remove and reboot...voila!
