MacBook Pro Flashing Logon Screen After Loading To Half Way.

[Kelvin Fideedle]

Hello,
I have a MacBook Pro 13" Early - 2015 Retina Display.

After the newest update through Apple Computers.
I have realised after I have logged on and loads to half way. The screen just blacks out and every few seconds flashes the logon screen.
So basically I open up my computer. I log onto my account. When the bar loads to half way it just blacks out. The screens turns into a really dark blue, pretty close to black. Then it starts flashing the logon screen every few seconds. The logon screen looks like its frozen and its just a picture just flashing. Then it just repeats it on and on and doesn't do anything. I left it there for around a hour, but it still continuously does that.

Also this may be a warning to the people with Apple Laptops. Either it affected or unaffected you after the update.

It would be a life saver if someone could help me solve this problem as school is just around the corner. This laptop has all of my notes and programs for school. And if I was go use another computer, it would take many hours to install all of the programs and I don't really want this since this is a really old laptop.

Try starting up in safe mode.
Try starting up in Recovery mode.

If you can get into Recovery Mode which chas_m suggested and have a Time Machine backup, you can roll it back to before the update. With no backup the only other suggestion is to reinstall OS X.

If nothing works I would be calling Apple. If you have an apple store close by make an appointment at the Genius bar.
