Q: Black Screen But Can See My Cursor

Oops spoke too soon. Was seconds away from finishing install screen, but just when black again after that

Jesseinma- THANK YOU!

My sister-in-law just had this happen, took her macbook to the Apple store and they wiped her computer to fix it.  Fortunately, I did a quick search first and saw your awesome directions and it worked like a charm.  Thank you again for posting this invaluable information!

Genious! it worked.

Brilliant, well done, great fix.

Yes! worked for me too, after two nights of failed recovery attempts. thank you jesseinma

Spiro.r's suggestion appears to have gotten us unstuck.  Thanks.

Thank You very much jesseinma!!! Whoop! Whoop! I got my laptop up and running!! Much Mahalo from Honolulu, HI!

spiro.r's  solution worked for me.  I tried all the other solutions on this thread and from other threads about typing the username and password "blindly" but not of that worked.  I booted into single user mode and executed these commands and rebooted and it worked immediately.

For me, I think the problem originated because I didn't have enough free disk space to fully install the last 10.9.4 Mavericks combo update (I only had 1-2 GB).  I booted into single user mode, moved about 30 GB of files to an external hard drive, executed the commands listed above, rebooted, and it worked!

Thank you jesseinma really helped me out I was going to have an emotional Breakdown

This took a couple of tries, but it worked! Thanks for the post.

P.S. Come on Apple, you know better than to release something like this.

jesseinma's fix worked for me too! Thank you 1000 times for posting that!

OMG this worked. I was freaking out/getting annoyed because I recently had other problems with my MacBook Pro. Thank you a million times jesseinma!

Thank you Jessieinma! Had to hit enter and enter password a couple of times after getting back to black screen but eventually got it to work! Now I can cancel my appt at the Apple store tomorrow. Woo hoo!

Hey all- jesseinma's solution did not work for me, nor did the PRAM restart and certainly didn't want to erase my HD.

Apple knows this is an issue and has now dedicated a team to fixing the problem in their call center.  Call them!

The Apple tech walked me through entering in some code (after holding down Command S) that took care of the problem and it took less than 10 min to do.  I'm sorry I didn't save exactly what he told me to enter in.

Call them!!!

Many Thanks Jesseinma! worked for me. Mine is a 15-inch, Mid 2009 Mac-Pro.
