  There was several abnormal stoppages in the last days. A negative stop code may indicate a hardware problem. The precise meaning of the codes is not publicly documented.

  If you haven't already done so, you can try to reset the system management controller. Otherwise, or if the reset has no effect, see below.

  Do a 'genius' one appointment at an Apple Store, or select another authorized service provider. You may need to leave the machine there for several days.

  Back up the data on the internal disks before you turn on your computer to anyone. There are ways to back up a computer that is not fully functional - ask if you need advice.

  If privacy is a concern, delete the partitions of data with the ability to write zeros * (do it only if you have at least two backups complete, independent, and you know how to restore on a blank disc from any one of them.) Do not delete the recovery partition, if it is present.

  Keep your confidential data safe during the repair of the equipment

• Mid-2015 MacBook Pro won't start every 2 weeks, need to restore from a backup.

  Hello all, big problem, Apple says that it is not material (although I'm not sure), but if not, then there must be some sort of conflict between my installed software and the new model of MacBook Pro mid-2015. Help!

  The problem here is that I've been running EXACTLY the same configuration on a MacBook Pro 2012 since, well, 2012, without any problem. But when I received the new machine in December, I migrated everything on (using Migration Assistant), I have installed a Bootcamp partition, migrated my old installation of Windows on the use of WinClone, and everything was fine for about 2 weeks. This is the same process as I did when I upgraded the machine from 2009 to 2012 also machine well.

  Suddenly one day, starting from Windows to Mac OS, I watched the progress bar filling, then stop, then the screen went black. No sound, nothing. I hit the power button and the same sequence. Progress bar about 3/4 of way filled, on the screen then black, then the unit turns off.

  I called Apple, went to two Apple stores, and we all tried to run disk utility to fix the problem. But every time I find myself with a message "Invalid node structure. The volume could not be completely checked. File system check exit code 8. Updated scores of start-up of the volume as required. File system check or repair a failure. Operation failed... "The topic on this bed,"first aid process has failed, if possible, back up the data on this volume. »

  The idea of first re - install the operating system didn't work... apparently there was a problem with the volume at this point so he would not restore. The next option was to completely erase the partition and then restore the backup. That worked, but then the entire process repeated two weeks later.

  I have been through this process 7 ~ 8 times since December! It seems to happen every two weeks and no one can tell me why it's happening on this new machine, but I have NOT had the problem on the old machine running the same configuration.

  
  

  Apple said it might have something to do with execution Tuxera NTFS on Mac (if I can share documents across side Windows). I have not removed... Tuxera two restorations there is no change.

  I also use Paragon HFS + for Windows, because most of my material is actually stored on the Mac side. I have NOT yet removed this (current running Windows 10) because I have NO idea why or how something running on the Windows side could affect the operating system volume on the side of Mac... especially when everything I do is opening and closing things as Word documents.

  I have log files and screenshots (I write below a few... but there are many others). Apple says "it is not a hardware problem" so they won't have to help understand if it's just software. I beg the community to help!

  Here's what I new material:

  MacBook Pro (retina, 15 inch, mid-2015)

  Intel Core i7 2.8 GHz

  16 GB 1600 MHz DDR3

  AMD Radeon R9 M370X 2048 MB

  This graphics card is the NEW one, first, that I do business with AMD

  My OLD machine is:

  MacBook Pro (15-inch, mid-2012)

  Intel Core i7 2.7 GHz

  16 GB 1600 MHz DDR3

  Intel HD Graphics 4000 1536 MB

  Any help or ideas are appreciated!

  

  Suddenly one day, starting from Windows to Mac OS, I watched the progress bar filling, then stop, then the screen went black. No sound, nothing. I hit the power button and the same sequence. Progress bar about 3/4 of way filled, on the screen then black, then the unit turns off.

  This occurs when the drive Boot CAN get the initial Blob of the software off the drive with the boot loader, but when he tried to mount the disk with the file system, it can not be mounted. It runs a single past of [essential] disk first aid. If the drive cannot be mounted, your Mac can not do something useful, he died.

  If the problem could not be fixed quickly, you should have been advised to REPLACE this hard drive.

  This is what you need to do now and stop wasting your time. A new drive costs less than $ 100 and will solve your problems.

  If you got less than a month ago, it is still under warranty of 90 days (I think), so take it back to the Apple Store you got OR no matter what Apple Store close to you if you bought it online.
