Has anyone experienced a problem with the 2016-002 update of El Capitan? For me, after update, the boot process starts normally, but with the progress bar is halfway through, the monitor goes off, occasionally flashing...showing that the progress bar is not moving. It never seems to finish the boot.
My Mac Pro still boots from another disk with the previous OS. Running fsck verifies that the disk is fine.
Should I retry the install...or is it s problem with the boot.efi file?
