Hello. My name is***** to JustAnswer. I'm reviewing your question now, and will post back with your reply momentarily.
To start up into Safe Mode (to Safe Boot), do this:
Open your finder ( magnifying glass ) type in disk utility, and launch the disk utility application.On the left side of the disk utility window, click your mac hd, then at the upper right hand side, click first aid. Then click run first aid.
Then reboot and see if you can sign into normal user acct. Let me know the results and we will go from there.
