Do not start (El Capitan, mid 2012 Macbook Pro)

Hi all!

I'm having serious problems with my Unibody Macbook Pro mid 2012 since a few days ago.

On Sunday, all of a sudden the computer really slow and G.Chrome used a lot of CPU, so I rebooted the machine, but on reboot, I couldn't get the operating system to start. I kept getting a white screen with the circle-slash (prohibitory sign) and a file of o Apple logo with the question mark that would Flash briefly before returning to the slash of circle.

After leaving the computer alone for half an hour, it starts without a problem. I rebooted again to see if the problem disappeared, but he returned to the circle-slash. I tried the resets of LANDAU and SMC but no result. I couldn't enter Recovery Mode (via CMD + R, because he just left me a white screen). I got the computer to reboot again and ran first aid to disk on the disk and partition utility and I got a message that says that there is only a problem with the map of partition with could prevent from starting.

So, I downloaded El Capitan on the App store, is an installation of the flash player program, reformatted the whole drive and reinstalled the operating system but I always get the slash circle approximately 85% of the time and cannot set the Mode of recovery without the flash player. Also, I can't access Single User Mode (CMD + S) I get an error that says something about a problem loading the kernel cache.

In summary: when the operating system loads (15% of the time), it works well; but can not access the Recovery Mode in single user Mode.

What are my options?

Here are the instructions from Apple for your splash screen:

Your HARD drive may also be suspect or the connection with it.  Try to access the Internet, OPTION-COMMAND-R recovery on startup.   Then run disk utility > first aid.

Ciao.

  • Mid 2012 Macbook pro with 2 monitors generic?

    I have a 15 inch mid 2012 Macbook pro (the one with an optical drive), there a mini-Display port and a firewire port.  I have a few spare Dell monitors and I want to set up two monitors to it.  I know there is a DVD-I or VGA adapter mini-Display, but I can't find something-> firewire.  Is what I'm trying to do possible?

    This was after the 3 beep error and I couldn't restart the Mac with one of the 2 GB of Ram into the lower slot.

    Is there a way to test if the top housing is faulty or just dirty?

    Yes, the MBP will work with a single module of RAM installed, but there will be a slight performance decrease.  A MBP 2012 will accept a module of 8 GB RAM.

    Is there a way to test if the top housing is faulty or just dirty?

    Install each RAM module individually in each slot, leaving the other empty.  If the two RAM modules work in a slot and not the other, the slot is faulty.  Sometimes the adjustment screw can resuscitate the slot.  If this is not the case, make an appointment at an Apple store for a FREE evaluation.

  • Mid-2012, Macbook Pro 13 inch corrupt partition map

    I was connect my external hard drive that works 24 Fedora quite frequently beyond a few days. I use the option key during the startup key to choose the operating system. So now my OS X El Capitan only lights because of a partition error. I fixed that with the recovery of the internet, but I am 100% sure that this issue will come soon. Is there any solution for this? What is the cause of this problem?

    Any suggestions or comments would be appreciated.

    Is there any solution for this?

    Yes, a replacement hard drive. They are not terribly expensive and replacement is simple.

    What is the cause of this problem?

    Contamination, mechanical damage, age... one of these factors.

  • RAM upgrade for mid-2012 MacBook Pro question?

    So, I bought some RAM Corsair (2 x 8 GB) to install in my MacBook Pro for mid-2012. It has been well over a month now and I get freezes and flaws that were not there when the Apple RAM stock has already been installed. My question is... are it freezes and the seeds one result of the brand of RAM I have installed (Corsair) or the fact that I am superior to the amount of 8 GB of RAM recommended for this laptop of Apple to the particular address?

    Thank you.

    As you can see here, your MBP can, indeed, support for 16 GB of RAM. However, DIMMs must meet Apple specifications which are often much more demanding that really meant DIMMS for PC can meet. One of the advantages of buying from OWC (in the link) is that they provide 100% support so their products need to be designed with the Mac in mind. If you have no problem with DIMM Apple, but you do with Corsair DIMMS, I would say getting them replaced or, better yet, to get a refund.

  • Mid 2012 MacBook Pro starts only with the external hard drive

    I have a MacBook 2012 mid Pro and whenever I try to start it only shows the folder with question mark flashing. But, whenever I plug in my external hard drive, it boots. I also tried selecting the boot drive and the interns don't show, but once in the external plug-in, it shows externally as Macintosh HD. I also tried to reinstall OS X but it says I can't you this player.

    Thank you

    While in the drive external hard, that I hope has the same operating system, can you go to utilities utilities disk-file and run a repair of the internal drive and repair permissions? You could also do the same thing in starting mode of recovery-command keys R at startup. Using the recovery disk utilities. If you can't get the internal drive to show everyone, most likely the drive is bad. Then, you will need to replace it.

  • Mid 2012 MacBook pro test equipment

    I got the error 4BAT/1/40000000: 0x8984fb90 while doing the test hardware. Can anyone advise if this is a question of logic board or battery? I checked in the coconut battery test and battery seems fine. I had this problem all of a sudden as I was getting backup from 2-3 hours, but all of a sudden, it worked only when power adapter connected. I checked using different power adapt too and also tried to remove the battery (it was working fine when connected). Any clue? If it's a question of logic board then I better start my computer or notebook.
