MacBook Freezing at OS X Utilities

My MacBook Air had its main logic board replaced a few weeks ago. After I got it back, it was crashing all the time whilst using the internet browser etc. I decided to wipe the laptop and try to reinstall from new.

When it boots, it boots to a folder with a question mark, then I press command and R, it loads to internet recovery fine, no crashing. I get to disk utilities and I press on reinstall OS X and I get so far to pressing reinstall but it then crashes and the only way to turn it off is to fully shut it down.

I have tried every single solution, but every single time we get to OS X Utilities, the computer will just freeze.

I have done this around 20 times but every single time, it freezes. I just can't find anything that works.

Thanks in advance.

2 questions. Who replaced your board, and why did they replace your board?


Hi there everyone,

Stormfront in the UK, an authorised apple provider, replaced my logic board and they did this as the computer before just died and wouldn't turn on.

When I got it back with the new logic board, that's when the crashing began.

I have a USB that has MAC Sierra on it, however, when I try and boot up the computer with it, it won't show, only internet recovery shows.

I have done the test booting up with D and it says everything is fine in working order.

As I said before, computer turns on fine, boots into internet recovery, loads fine and then as soon as I get to OS X Utilities, that's what it automatically crashes.

Just don't know what to do anymore as I am stuck on an island for a few weeks with no Apple Store.

You may want to create a memtestx86 usb stick for Mac and check your ram to begin with. I've seen Windows and Macs both crash after memory starts filling up to a point.

Next, I would run a Apple Hardware test:

Power on the mac then immediately press and hold the D key on your keyboard. Keep holding the D key until you see the Apple Hardware Test icon. Follow through the steps.

Another option, if the above tests work, is create a USB installer for OS/X -- once created power on holding the Option key and boot from the USB installer. In the case, for example, say El Capitan, you should get to a dialog that will let you run disk utility -- it may be that the copy of disk utility on the hard drive is corrupt.
