Clean install Mac OSX El Capitan/Sierra

One more thing. I’ve even tried internet recovery, but the same result. White screen at the end of loading after I enter my Wifi password. Attaching screenshot for your reference. As of this posting, Internet recovery also stuck at white screen and not doing anything.

Hello..

After failed attempts at usb installer, internet recovery and bootable Ubuntu, I thought I’ll try something else.

So I opened the physical hard disc from my Mac and plugged it in as an external HDD on my wife’s MacBook and installed OS X El Capitan on it.

To test if it works, I booted from this drive to the other Mac and it worked fine, just as the Ubuntu bootable did.

Then I plugged in the external HDD to my MacBook and tried to boot from it. Again it shows the progress bar with Apple logo. After going halfway through it, a weird multi coloured stripe shows up and the computer shuts down. I’m attaching screenshots for your reference. Please advise what this could be? Thanks

Hi, thanks for your reply.

I’m not being able to go up to disk utilities. When I click install El Capitan, it goes half way through the progress bar, and then the white screen comes and then shut down. Please check the pictures where I’ve tried to show how far I can go.

Regarding hard disk, I’m pretty sure it’s alright as it’s taken from my windows laptop which was running perfectly. Also, the hard disk that was present in this Mac is now in the windows laptop, and that is also running perfectly. So I’m assuming both hard disks are fine.

Regarding usb stick, I’ve tried with 3 different ones and all are doing the same thing. Also I’ve tried 3 different versions of the OS, El Capitan, Sierra and High Sierra, as that’s the latest my Mac is compatible with. But all OS versions and all USB sticks are behaving the same way.

Hi, thanks for your reply.

Its a 15” MacBook Pro, late 2011 model A1286.

When you say that there might be an issue with the GPU, how to fix that? Is it software issue or hardware? Also you mentioned to force to use intel GPU, but how? Thanks

Hello.

As per your suggestion, I made a bootable usb with Ubuntu on it. Tried to boot from it on my MacBook, but again failed. It’s stuck on a black screen after I select option 1 (try Ubuntu without installing); also stuck on black screen when I select option 2 ( install Ubuntu).

Just to rule out a faulty usb drive, I tried it on my wife’s MacBook Pro, and its booting from the same usb just fine.

So now to conclude, even usb bootable Ubuntu is not being able to load on my MacBook Pro. Now I’m really confused about what the problem is. Thanks

Hi there!!

Finally it worked. Switched to intel graphics and booted the OS. But the laptop is getting extremely hot as advised in the forums. Will try to tweak some more to get around it. Thanks a lot for your help!!

These are screenshots from the Ubuntu install attempt. Pls note that this same usb is working on another MacBook Pro, so the usb is fine.

Hi there, thanks again.

I’ll try to go through the instruction and see if I can get it working. Will update you on the result.
