I have bought MacBook Pro with OS X Yosemite two days ago. After I transferred my files through Windows sharing I come to know that Disk utility didn't install properly as it says damaged or incomplete. So I had to restore is as new.

First time it took more than 8 hrs because I slept after 5 hrs of wait. Then again I had to repair because I didn't find iMovie, iPhoto etc because it was in purchased items in iTunes but it also take ages and also I stopped migration through apple app because of same problem, took ages.

So I was afraid if data was saved somewhere so I restored again. I started at 3pm and it's 6.46 and it's not even half of it and saying 33 hours left. I followed Youtube videos, they says their repair takes just half an hour! Need help in a detailed and easy way. What does it mean by boot?

  • the problem is apple store is not in my city and i asked them they said it will take 2 days and money too!

there might be a better solution (below), but a slow internet is a slow internet. it will just be a less painful download. read the steps to see what you think and if it works for you.

  • so boot into the ailing os
  • if you don't have the yosemite installer, download via the app store. yes this might still be slow, but should be resumable and you can do other things while it goes.
  • download disk maker x, this is a prog that takes and osx installer app and makes an installer usb stick with the full os on it.
  • run diskmaker x and get an 8 gb usb stick and point it to the yosemite installer. be careful you choose the right disk to erase.
  • then just boot off the usb stick and it will install from the local installer files.

i use this program and depend on it to make installers for various machines


I would strongly advice you to visit the apple store for them to fix your Mac.

But if you insist doing it your self:

Turn off your mac.

Hold the cmd and the r and turn the Mac on by pressing the power button. (keep holding the cmd+r.)

Now you will get this:


First Run the Disk Utility application to Repair your disk. (do not Erase anything).

Next run the Reinstall OS X.

If you deleted the recovery for some reason, you need to use the Internet recovery to get it:

Immediately after hearing the Mac boot chime, hold down Command+Option+R – if you see the Apple logo you waited too long and need to reboot and try again.

You should now have a working Yosemite after waiting minimum a hour or much more depending on you Internet speed.

If you have erased Apple applications like iTunes ect.. then follow this instructions how to get them back. OS X Yosemite: Reinstall apps that came with your Mac

Finally back to transferring: How to transfer files from Windows PC to Mac.

Read and follow instructions from here. OS X Yosemite: Transfer your info from a computer.

  • Disk-Utility is a application, not a folder. If you used the ERASE the disk, than all your information has been erased from the disk. That was a big mistake! Now you have to start all over with installing everything that is why it asks you about itunes and iphoto. Those applications were per-installed on your computer by Apple and you deleted them. Seriously, get some help, we can not solve this online.

  • We need to come clean here: you did not erase the disk utility (it is a application), you erased the disk it self using the disk utility to do so.

  • well since you erased all from your disk now you have to reinstall all of it using the Internet. For example the Yosemite it self could take anywhere from a 1 hour to several hours (depending on your Internet speed), then you need to get all of the Apple applications as well (like iTunes and so on), that could take additional hours to do. Good luck and follow my instructions, and before you delete anything come here and ask.
