I tried to restart so many times and now I rebooted in recovery mode and I'm reinstalling. I keep getting a frozen desktop and the coloured spinning wheel whenever I try to quit the apps set to open on login.
However I live in Asia and have a slow internet connection... I get this screen.
SO I suppose I will try to go to bed and see what has happened by the morning. It makes me sick in the stomach when my computer is not working right. I did not have time to back up before I upgraded either. So, lesson learnt.
THis is is the first time I have had an issue with upgrading tho, I am on a 2014 fall MBP.
WIll update ate tomorrow I suppose.
