Booting to folder with a question mark
My macbook is intermittently booting to a folder with a question mark. At first I thought drive was bad so I bought a new ssd drive. After removing the old drive I was able to pull all my data off of it with no issues. I installed OS on the ssd drive and it worked for about a week before having the same issue again. I removed the ssd and was able to boot to it externally from a drive enclosure. I ordered a new sata cable from iFixit and am still having the same issue. It boots externally every time with no issues. The only think I can think of at this point is the connection on the motherboard that the sata cable plugs in to. Any ideas? Doesn't seem worth buying a new motherboard for this system.
