I have MBP 2013, after trying to update to the latest OS, I lost the ability to use my MAC. I am afraid to update to High Sierra due to previous issues. I worked for 3 days to get my MBP back up and running. I am not a computer person. It appears the problem hasn't been fixed. Apple, PLEASE help!!!!
