Mavericks won't complete a start-up in safe mode (shift key held down after the chime). It goes progresses slowly in the start-up process, then near the end of the process the screen goes blank and the computer automatically restarts in the normal mode. Does anyone know what is causing this 😕
What is your configuration?
Late 2012 27" iMac (1 TB Fusion drive) OS X 10.9.2.
I would shut down, remove power cord for 30 secs, startup and hold down the shift key as it chimes.
If that doesnt work then describe what happens, does it attempt to boot into safe drive?
As before, it just boots into 'normal' mode - no 'safe' mode.
Do you at least get the progress bar as if it were going to boot into safe mode?
No.
are you able to boot into single user mode and are you able to zap the pram?
Works for me now. What is interesting is the fix wasn't on the list of fixes for the new update.
I saw it on the list from apple. Seventh from the bottom:

The 10.9.2 update solved the issue with my MacMini (with fusion drive) unable to boot in safe mode 🙂
You are correct, don't know how I missed it.
Hi there friends
I don't have apple help in my city
I'm using MBP as desktop removed battery due to batter sensors issue.
It is late 2011.
It started with no startup tone chime than I set nvram so startup tone came but the persisting issue is grey bar at the startup blow apple logo that takes 20 min almost and after completion MBP turns off and requires manual turn on and upon re turning on again that grey bat appears same fasion.
Some one told me to go to safe mode and apply some changes but I can't go to safe mode with shift key startup login Id password bar appears and constant shift key press interrupts and again grey bat appears.
I don't know how to disable startup password and how to disable vault.

How did you get into Terminal? And what was the command to reverse the safe mode? I am in an infinite loop of where my iMAC (early 2009) running Mavericks is trying to boot into safe mode (long long long time for status bar to fill on gray apple logo screen) and then when it does, the machine shuts off. Power up and ............ same thing again.
won't start in safe mode
