At times, as you turn on your MacBook Pro you might see a grey or blue screen or it gets stuck at the Apple logo that never loads OS X. This can happen for a number of reasons, so it's one of the most frustrating things that can happen to a MacBook Pro, and troubleshooting it is no easy task. Here are few steps using which you can fix such start-up issues. Just have a look at these simple steps and try it out!!

Step 1: Disconnect all peripherals

One of the main causes for MacBook Pro startup problem is incompatible hardware connected to the machine. This can be your external hard drive, a printer, or even a USB hub. So, disconnect everything except the mouse and keyboard, and restart your MacBook Pro.

If your Mac starts this way, then it's an issue with one of those peripherals. To figure out exactly which-one is causing the issue, do trial-and-error method. So connect them back into your computer one by one, and restart. If one of them causes your computer to hang on the grey screen again, you've found your issue. If no devices are causing problems and your Mac still won't boot, then just proceed with the next step.

Step 2: Safe Boot your MacBook Pro

Safe boot makes your MacBook Pro to boot up with the minimum amount of drivers needed to make it work, and it checks your hard drive in the process. This might take a quite longer time to boot up. To achieve this, start up your laptop while holding down the Shift key until the Apple logo passes. If your Mac starts up with the safe boot, go ahead and restart the computer again and see if it boots up normally. If not, try the running the Disk Utility as explained below.

Step 3: Run Disk Utility

In case if the above two steps couldn’t start up your OS X normally, it's time to run Disk Utility and check out your hard drive. Go through the below steps:

(Note: Make sure you have data backup before running the Disk Utility)

  • Start your MacBook Pro by holding down Command + R (if you are running Snow Leopard or earlier version, find your OS installation disc, put it in the drive, and reboot your computer holding down C). This will boot you into a diagnostic mode.
  • Select the Disk Utility Option and your hard drive
  • Now click “Verify” and wait for Disk Utility to finish running
  • After it is done, if any issues are reported as a pop up then click “Repair Disk”
  • If nothing is reported then, click "Repair Permissions" and wait until the Disk Utility scans your hard drive again
  • If Disk Utility finds and repairs some problems, then just go ahead and reboot your MacBook Pro

In most of the cases, running Disk Utility will catch problems with startup issues. Sometimes a single file with the wrong permissions could cause the whole system to collapse, or if something's not in the right place it won't boot.

With the above-mentioned steps your MacBook Pro startup problems can be fixed. Before you run the Disk utility take back up of your entire data. In case either while repairing the disk or the permissions if any interruptions occur your entire data on the MacBook Pro will be lost. In such cases backup copy would help to restore them back else, just use the Remo Recover Mac tool to get back your lost data. The tool works exceptionally well to get back your entire data.
