Hi, 

 

I have a Macbook Pro 2011; lots of memory, 8gigs ram etc.  Newest version of Sierra recently installed. 

 

Whenever I startup the laptop either goes into a loop of restarting, restarting to a black screen or just loading into a white screen. I've tried some troubleshooting to no avail. I have:

 

1. BOOTED UP IN SAFE MODE:

Held shift while booting up. This just leads to white screen after apple logo, stuck there. 

 

2. TRIED RUNNING DISK UTILITY:

Started up while holding Command + R: Once again stuck on white screen 

 

3. INTERNET RECOVERY: 

Started while holding Command + Option + R: Able to select internet network, then screen is stuck on spinning globe 

 

4. RESET NVRAM: 

Command + Option + P + R : Causes reboot loop 

 

5. USING TERMINAL IN SINGLE USER MODE:

Command S; check for file consistency and remount boot volume: says "system modified" first, then "system ok" finally. After this, I restart, stuck once again on white screen. 

 

I can't even reinstall because I can't get to the disk utility or any other screen beyond the apple logo. 

 

I've even tried letting the power rundown and starting it again, but, no avail. 

 

The laptop is also piping hot if on for any amount of time. 

 

Please, any tips would be greatly appreciated!

 

Thank you 

 

Greg
