Q: Terminal opens by itself; strange alert messages
I have an early 2009 Mac Pro tower. It's been running fine under El Capitan, but recently several things happen that I can't explain and wanted to see if others are having issues and how they may have dealt with them. I use the latest update of El Capitan (10.11.6), but the first problem below has been going on since the first El Capitan release.
First off, I cannot simply restart my computer. When I select "Restart" it will not shutdown, ever. I must do it manually by pushing the start button, then restart manually. I read to unplug the computer for 15 min. and it will clear up the problem. It worked one time. If I shutdown and unplug it, it will work again, but only one time. I would have to keep unplugging it every time I shut it down to work the next time I start up.
Also, I often leave my computer on during the night. Lately, seems like since the last El Capitan update, when I first sit down in the morning, I find the terminal open. That is strange because I never open the terminal. I'm scared of the terminal :-) Twice I've found an alert message on the screen when I sit down in the morning to use the computer. I have attached two examples to this note. I'm wondering if someone could help decipher them. If someone is trying to hack my computer, I have no idea what is happening, or how to correct and protect.
Thank you in advance for any help you can offer!
Michael
