Gray
Screen error can occur during the startup of Mac and it is a common
occuring problem in Mac OS X. Gray Screen can show up just after you
started or restarted the Mac. When Mac is in the process of startup,
a blue screen occurs but sometimes it may change to the Gray Screen
and system hangs.
On the Gray Screen you can see the Apple logo, spinning gear,
spinning globe. Mac gets stuck at this screen, you will not hear any
hard drive sound or fan sound, it will be like everything just
stopped.
How
Gray Screen of Death might occur on OS X?
Peripheral issue can cause the Gray Screen of error i.e.
whenever a defected or bad peripheral gets connected to Mac, it will
prevent your Mac to startup. Mac may also gets stuck becuase of a
non-responvsive peripheral. One of the most common form of this
condition is when a bad peripheral causes the signalling pins on
Mac's port to stuck in one condition and these can cause the Mac to
freeze and failes to boot properly.
Steps
to solve the Gray Screen error:
- Disconnect all the external peripherals connected to the Mac .
- Now, forcefully turn Mac off by pressing the power button and then start again.
- Start the Mac backup and if backup starts normally then it is sure that the problem is with the peripherals only.
- Now turn off Mac and start checking the peripherals one by one. If the Mac shows the error while attaching to a particular external peripheral then it will be the defected peripheral causing the issue.
So by this, you can find the bad peripheral if any. In
case you find a bad peripheral, it is advisable to first change the
cable of the peripheral but if the problem still prvails then change
the peripheral.
If
peripherals are working fine then possible solutions for this error:
- Try to start Mac in safe mode.
- Reset the NVRAM / PRAM.
- Remove any third party RAM Or internal hardware from Mac.
- Try using disk utility.
If above solutions fails and in middle of all this you
have lost your important data then it is highly recommended to use a
recovery tool to get every piece of lost files back on Mac.
