• I have problems to restart of Yosemite, after power failure during the new backup, and now HD is also blocked.

• Assistance required after you download Sierra - locked in a spiral of failure of the Installation

  Hello - I am a student of the University who made the mistake of thinking I had to upgrade my OS system after seeing some updates new flashy in the Sierra. Long story short, that my computer is locked into a cycle where I restarts and the installation process will begin installation but end abruptly and ask me to reboot again.

  I have exams and papers due and seriously want access to my data again. I don't have a back up of my files. As such, I am looking for a method that will allow me access to my files that I need to be able to read notes, print etc.

  Details: I have an old MBPro by the end of 2011. He was on as the primary OS x Lion. I had updated some time later. More recently, I got El Capitan and it worked very well. I downloaded Sierra in the background as I did work at home and after installing it, it asked me to reboot. This was the point that I was able to come back from. Reboot after installation scenario is as follows:

  -A progress bar comes up saying 34 minutes until completion

  -The progress bar goes to 33 minutes until completion

  -Beginning of fans of my computer acting upward and the bar stops and crashes of progression

  -The installation process says he doesn't have and asks me to restart my computer

  Specifically, I get the message 'Mac OS could not be installed on your computer. File system check or repair a failure. Quit the installer to restart your computer and try again. »

  When I quit the installer of the OS, I am taken to the startup disk option and asked to choose a system to reboot my computer with. I see 'Macintosh HD macOS 10.11.4' but when I click on it and try to restart I get the following error message, "you cannot change the disk on the disk selected. Startup disk could not gather enough information on the selected disk. »

  Things I've tried:

  Internet recovery mode: I went here to do a restore of the Mac OS x comes with my computer (Lion). This attempt fails and the computer tells me I can't downgrade because a more recent OSX is already on my computer...

  Recovery mode: I tried to come back just El Capitan from here. When I try to do the process will take literally one second before I get a notification saying: "an error occurred during the preparation of the installation. Try to rerun this application".

  Disk utility: I tried to do first aid and repair on this menu on the big disk image (since some of them pop up... I'm sure that the big one is my computer and the small setup of Sierra is?). I see that I 115Gigs franco 319Gigs departure. When I click on check and repair, the process takes some time and seems as he goes to halfway through before I get errors in the two. Repair error wonder backup my data.

  -some specific stuff; the journal for the repair of first aid says something like: the Macintosh HD volume could not be completely checked. File system check exit code is 8. Update support partition for the volume as required. File system check or repair a failure. Operation failed... »

  Safe mode: I can't start in safe mode. My computer will load the apple logo, progress on 3/4ths of the way start-up and then crash on its own and not restart.

  Things I have tried:

  Constituting a new boot USB of OS Sierra - I read that in so doing I can substitute the installation process that is going on right now on my computer and start a new... I hope one that works. I was not able to do this again, because I need someone to another macbook to make it and none of my friends won't let me touch their computers after the fiasco that happened on mine... Can I get some feedback on this?

  Backup: I don't have an external hard drive... I'm willing to buy one if necessary, but I don't know how to make a backup in a world where I don't have access to the major functional sections of my computer. Also, if my computer is * session here now, I'm worried that a backup will be essentially a * a backup... is this the work of the computer?

  Other thoughts:

  -my computer was working fine before I tried the upgrade... no complaints on my end, it was a real trooper

  -Maybe the download was corrupted?

  -I learned today that the operating system installation process requires internet connection - maybe that my internet connection is bad?

  -on that note, I want to say I tried a lot of different things. Been in different parts of the campus (different parts of my dorm building, IT support across campus, etc.). My University has also 3 options of WIFI, but each requires a separate verification process. Throughout this process, I have been connected to one of these methods. Switching may help? But, if I can't do the verification step (i.e. open a browser and type in the details of my student specific to actually use the web), I do not think that this will help you a lot. In addition, I am sure that I am already using one of the less frequently used options.

  I want to avoid a permanent possible deletion because there are important things on my computer.

  Any advice? Enjoy it!

  Same problem here on my Mac Mini end of 2012. I couldn't find any fix so far. The machine worked perfectly fine before with El Capitan and had about 50 GB of available disk space. I have use any version beta of Sierra, but officially released one that came yesterday. Really disappointing to see the new system operating software with fundamental questions and no good way to solve it.

  Any help really appreciated.

• There's the iPhone battery chargers 5 that use no electricity.  For use in a power failure.

  There's the iPhone battery chargers 5 that use no electricity.  For use during a power failure.

  Your best bet is an accumulator.  I have one I got on Amazon by EC Tech.  It is a brick, but it will charge my iPhone and the iPad, if the current is cut off.  You just need to load the brick and keep it in an emergency.

• Of failure, white screen MacBook Pro HARD drive try to boot from the external HARD drive

  Hello

  I have a 2008 Macbook Pro which is having some problems, I was able to fix them, but eventually the hard drive failed. I know that because at startup until it would have a white screen Uni (no logo) and you can hear a clicking on in the lower left corner. I thought initially it was a memory problem, but after opening and verification of memory, it's clearly the hard drive.

  I solved this problem temporarily (until I can replace the HARD disk) by installing El captain on an external HARD disc and start from that. Here's the twist, I couldn't he can begin to El captain, I tried CMD + R, CMD + OPT + R, CMD + OPT + R + P and now shift. Everything that's happened would be that clicks would cease to release the keys.

  I left the macbook on while I'm at work, when I got home it was on the screen to connect the external HARD drive.

  I accidentally closed the macbook yesterday and again once when I tried to log on, I could not and I left it on a white screen while I was sleeping. There is a possibility that he may have launched from the HARD drive when I get home, but if not, is there something that escapes me to force do this?

  See you soon

  Usually start up to a blank screen without the Apple Logo, may report one of the following:

  • Hardware failure
  • Boot drive is not recognized as valid and updated updated
  • OS X essential software is missing, hurt moved or renamed or corrupt
  • A firmware update is necessary

  No matter who, in order to boot from an external drive "bootable", you would normally hold down the Option key until you get a screen that offers a number of devices to try to boot from.

  Alternatively, you can try holding down the C key to try to boot from the external drive.

  If none of these startup options work, then the bootable disc or the USB port on your MacBook Pro can be the question.

  Since you have a Mac pre-2013, if you hold down the D key while booting, the built-in Apple Hardware Test should start up.  This can help to identify hardware problems.

What are the other options of best for me? and this is the price charged for the motherboard, even as they say? can I have any apple legal right againt for replacement?

  You can test it by connecting via USB, a boot disk.  If the Mac recognizes, the Mac, boots, then the internal drive or connection that is the problem.  Is it is not recognized, then it may very well be a logic card problem.

  Ciao.

  Hello Mido, start safe mode and see if the install dmg will install properly.

  Restart now ' shift '.

  (Wait to take more time to start in this way because it runs a check of directory first. Also give it some time after the start because he runs maintenance routines at the beginning.)

• Time Machine backup failure

  I get the message:

  Time Machine could not complete the backup "Backups Time Machine". Full backup impossible. An error occurred during the creation of the backup folder.

  I reboot the system and am able to do the backup.

  Three questions:

  1 is my default backup drive and must be replaced?

  2. If I get a new drive, do I need to do any formatting when connecting it to my system?

  3. is there anything else that would work not to mention that the system restarts?

  Thank you!

  I should add that failures occur about once or twice a week.
