2012 Macbook Pro suddenly turned slow two weeks ago, now it keeps rebooting while trying to reinstall OS X El Capitan. Afraid it's dead!

Hi everyone.


I own a Macbook Pro from summer 2012, just after an upgrade in the hardware. Can't remember exact stats, and now I can't get anything out from it.

It has been running fairly decent with no problems until two weeks ago, the day after a small update of remote desktop, where it suddenly took 10 minutes to boot the computer, and opening apps like Safari took +1 minute. There was no error messages at any time.


I feared an impending hardware failure and bought an external HD and made a Time Machine backup of the 206 GB's of data I have in total, it took 2,5 days! It would seem to be on pause for 20 minutes and then resume copying data slowly.

However I got the full copy made.


Then I ran Etrecheck, but wasn't wise enough to copy it to another device, so I can't give you the full report, but the results were only 1 major issue: "It took more than 45 minutes to run", two smaller issues were unverified apps all with matches in the white list and no SSD HD. That's all.

I also managed to run DiscUtility and check the HD, no failures reported. The check took a whole night...


Now after the backup was secured, I tried to reinstall El Capitan using the recovery tool. It stopped quite soon and moved nowhere for 18 hours, whereafter I turned the computer off and on again. Then this screen started coming over and over again, and I can't seem to stop the updating from trying and then fail and reboot.

Assuming the disk drive hasn't failed:


Internet/Network Recovery of El Capitan or Later on a Clean Disk


If possible backup your files before proceeding.


  1. Restart the computer. Immediately after the chime hold down the (Command-Option-R) keys until a globe appears.
  2. The Utility Menu will appear in from 5-20 minutes. Be patient.
  3. Select Disk Utility and click on the Continue button.
  4. When Disk Utility loads select the drive (usually, the out-dented entry) from the side list.
  5. Click on the Erase tab in Disk Utility's main window. A panel will drop down.
  6. Set the partition scheme to GUID.
  7. Set the Format type to APFS (SSDs only) or Mac OS Extended (Journaled.)
  8. Click on the Apply button, then click on the Done button when it activates.
  9. Quit Disk Utility and return to the Utility Menu.
  10. Select Reinstall OS X and click on the Continue button.


Note:

1. To install the version of OS X that was currently installed use Command-Option-R.

2. To install the original factory version when the computer was new use Command-Option-Shift-R.


If the above fails because the disk drive has failed then you will need to replace the disk drive.

So now I'm waiting for a new SATA cable and crossing my fingers that it will fix everything. If it's not working after replacing the cable, then I'm pulling the plug and out for a new Macbook.


Do you think it will work with a new cable, or might it as well be the motherboard or some other component that is failing?


I/O errors I would not suspect the logic board as a first guess.


If it wasn't stated earlier it should have been: "always change the SATA cable when upgrading a new HD."


It is standard procedure for Apple Store HD replacements to include a new SATA cable—and this is for good reason.

Hi all, so sorry for my very delayed reply!


I installed the new HD cable and the Macbook turned on without any more problems - however I wasn't able to reinstall High Sierra, I kept getting the "servers are not available" error. Instead I was able to reinstall OS X Lion, which was the original version of OS X on the machine, using the standard recovery without internet. From there I could update OS X to El Capitan, and then on to High Sierra (though I am reluctant to go for High Sierra, as it would make my MS Office 2011 incompatible...) So I'm still using El Capitan. I recovered my files from my backup, and haven't lost any data!


So I can very much support the claim from LeroyDouglas: "always change the SATA cable when upgrading a new HD." :-D


Thanks for your help everyone who wrote replies.

Kind regards, Thomas

Being as you seem to use the machine minimally , I guess that depends on how deep your pockets.

Thank you very much for your reply!


I managed to get OS X High Sierra installed using internet recovery the way you listed above.

However, my computer is still running slowly.

I have made another run of EtreCheck, report listed below. Note this is with a completely newly reinstalled operating system and no extra apps or programs...! That explains the missing time machine backup...


I sense that something I broken inside my computer, but how can I tell what it is??
