Load bar at start up, then shut down. HELP NEEDED URGENTLY!!!

Tom,

you’ll need to use a bootable external drive to be able to back up what you can. Alternatively, if you have access to a FireWire 800 cable and another Mac with a FireWire 800 port, you can boot your MacBook Pro in Target Disk mode to have it act like an external hard drive to the second Mac, and copy what you can to the second Mac. Once you’ve salvaged what you can, boot into Recovery mode again and run Disk Utility to erase your internal disk, then shut down. When you power up again, OS X Internet Recovery will kick in, reïnstalling your MacBook Pro’s original version of OS X — probably Lion — from Apple’s servers. (If you can, connect via Ethernet cable rather than through wi-fi, to minimize download time.) Once it’s been reïnstalled, you can run Software Update to get it up to 10.7.5, and from there you could redownload and reïnstall Mavericks.

Tom,

you can try this in the interim: boot into your MacBook Pro’s Recovery mode by holding down a Command key and the R key as it starts up. When the Mac OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that it found errors, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart into normal mode. Do you still get the same grey screen + progress bar + beach ball of doom?

HI LowLuster,

I hope this message will find you sooner then later. I just tried to turn on my Mac Pro 2012. It has 4 DDRs in it and two SSDs on PCI card. One SSD has system and the other one was Fresh, hadn't use it yet. Same issue. Startup bar goes to about 80% and shuts down my Mac. Tried all the steps described here but cannot get to the disc utility panel. one of the DDRs snide has my time machine that backs up everything. Is there any way to access it without removing it from my Mac? Any other steps?

thank you

Hello!

I have the similiae problem. I got to the disk utility step however on my window it doesn't give the option to verify disk. There is a first aid icon, which I already tried, but no verify disk under disk utility. Any suggestions?

This the long way.. no need to reinstal apps/ programs...this has happened to me multiple times...

If the failing disk is internal..purchase same size or larger capacity external drive..boot into recovery mode.. then get a os dvd and install os on external drive.. boot from external.. download latest os from apple website..and install this on failed internal WITHOUT erasing or formatting.. once done.. everything will work as before all programs , settings , files etc are untouched

Get an External drive and install OS X on that and or restore to that external from your time machine backup.

Your internal drive has failed and will need to be replaced. you can do that yourself if you are out of warranty or have Apple do it once you take it in if you still have a warranty on the system.

But for right now your only 2 options are to make an external drive as you boot/running drive or replace the internal drive yourself today or tomorrow. With either you'll need to reinstall OS X and programs or restore from a Time Machine backup to either of those 2 options.

What I mean is your internal drive has failed.

With any Mac you can connect an external drive and use either the original system discs that came with your Mac (If it came with discs) or the Online Internet Recovery system to Reinstall OS X on that external and or Restore from a Time Machine backup you made previously to that external and run the system from that external drive.

As to your programs if you have the license keys for them you can reinstall them. If you don't have the license keys you might be able to get them from the vendor. That is something you would need to contact the vendor about.

If they were downloaded from the Mac App Store once you sign in to the MAS with the same Apple ID used to buy them they will be available for download and install.

I have no idea what you mean, so I think I'll just wait 'til Friday, and use my PC desktop for the time being. I've installed some apps (some quite expensive too), does that mean I'll lose them and have to repay for them?

this worked for me in similar situation! thanks!

I have the same issue, but the verification didn't take the progress bar away. My issue started when the system restarted from the upgrade to the newest iOS. Any ideas on what else might help?

but what if in the middle of the repair to the disk it always gets stuck on it should be 146 instead of 158 then the beach ball of doom comes up and the thing stops going as in it never gets repaired cas i left it on for 3 days just to see if it would finish repairing but no the loading sign just kept going on forever and i still cant boot up i have even tried to install mac os sierra again and and no the disks are all locked i can only access disk utility but its useless even with an internet connection please help if you can text me the solution to (714)-8181550 my name is andrew

This helped me recover my computer. Thank you so much!

So I'm having same problem once I've down this it says appears ok info to restart and does same thing any other ideas??

Hey!! Just wondering if you had any luck?!:( our mac book pro is doing the same and can't seem to find anyone that found a solution!!:(
