Question: My MacBook can't find startup disk after reinstalling macOS
I have a 12 inch Macbook that I bought early 2017. it has worked perfectly for little over a year until the last couple of weeks.
every now and then the screen froze and then the Mac restarted with blinking folder with a question mark. after restarting it a couple of every thing worked fine again. it seemed to happen more often when it was charging or it was fully charged. I tried a couple of times to repair the startup disk in the disk utility but that didn't help. I then erased the startup disk and reinstalled the macOS Sierra again but the same problem still occurs.
Anyone who has any idea what it can be and how to fix it?
