After upgrade to 10.12.2 macbook pro has black screen

Last night I did upgrade my MBP in 10.12.2

While updating the MBP has launched a sound shrill and is locked for a while, but after a while he completed the update and I could use the Mac for the rest of the evening.

This morning, however, after boing Startup and the appearance of the apple, it appeared a black screen with only the visible white cursor and the Mac no longer worked.

I tried resetting the NVRAM, the SMC reset, but it did not do anything. When started in Safe Mode I can get to enter the password of my profile, but after still has to be black screen.

I rebooted into recovery mode to do a test to the system disk, but that's ok.

The problem continues as before.

I asked Apple service if it was a known issue and if they had a solution to give me, that was not to reinstall your MacOsX and recovering from a Time Machine backup, but they refused to give me information because the MacBook Pro obsolete.

It 'happened to someone else and was able to solve it?

The my mac configuration is:

MacBook Pro 13" early 2011, 16GB RAM, Startup Disk SSD Crucial MX500 1TB
