I have "Macbook (13-inch, Mid 2010)" it has white plastic case with 4GB 1067MHz DDR3 RAM and NVIDIA Geforce 320M 256MB.
Model Identifier: MacBook 7,1
Boot ROM Version: MB71.003F.B00.18022149
SMC Version (system): 1.60f6
It had originally El Capitan installed. It booted nicely every time. I think that I didn't go trough all software updates it provided.
I did a fresh install of High Sierra from USB flash drive. I went trough some installation steps with errors and restarts.
Now when I boot, there is a 50% chance of booting to OS.
Other times I see grey Apple logo and a progress bar that is filling slowly, gets to 100% and then nothing happens for a whole day.
There were some updates of software in between, but they are not related to this booting problem.
Is there any way how to fix this problem?
Here's a list of things I have done to test/diagnose the problem:
- three passes of extended Apple Hardware Test; passed OK.
First Aid on HDD; passed OK.
First Aid test from Disk Utility passed with no errors
smartctlshort and long HDD tests passed with no errors.
I tried to reset NVRAM and SMC. Didn't help.
I recently did an update in High Sierra and update of the SMC to the latest version provided for my hardware. Didn't help.
I was doing some High Sierra updates, re-installs to Lion, El Capitan and Snow leopard and my Boot ROM Version has changed from
22.214.171.124according to this article from 31.10.2018, my firmware was latest to that day, so i probably have a recent firmware.
diskutil info disk0 | grep SMARTis
SMART Status: Verifiedbut as I said I used smartctl to run short and long SMART tests which passed. Anyway SMART looking ok may mean nothing.
- removed second partition formatted 320GB partition to APFS and reinstalled high sierra from usb flash drive, original distribution from apple store. didn't help it freezes every other boot.
