Flashing question mark folder on startup -- sometimes
The flashing question mark on startup has been addressed quite a few times here, but my situation has a bit of a twist, because I’m only getting the flashing question mark sometimes. When I get it, I shut down my macbook, try starting up again, and it’ll start up fine. Sometimes I have to try 3 or 4 times to get it to work, but eventually (so far) it does work. And once it’s started up, it works just fine. So why would the flashing question mark only appear sometimes?
I ran disk utility. It couldn’t find anything wrong with the SSD. I’ve tried resetting the pram and smc. I’ve tried taking out the ssd and cleaning the connectors. Didn’t help.
I could simply never shut down the laptop, but then I run into another problem, which is that it isn’t waking from sleep properly.
Any ideas why the question mark folder would only appear sometimes?
