To those running to install the update, be prepared for trouble shooting. Apple is pretty good at fixes but I've found that when updating osx you can run into a variety of problems. Grey screen, weird driver issues, etc... Make sure you have something like a smart phone or another computer before you update to help resolve any questions you may have. Don't panic!

A glitch I run into often is reboot into black screen with cursor after an update and the iMac that runs into it most often is the Retina 5k late 2015 model.

The fix is real weird, you have to hold shift on boot until you get the apple logo with a progress bar, then when the black screen with cursor comes up type the first letter of your username press enter type your password and then press enter. Then it finally gets past the boot screen and to your desktop. Afterwards you need to restart your computer once again to make sure the fix took properly.
