    My new 2017 iMac will not restart or shutdown unless I eject my external drive that has my iTunes library on it, It hangs on a black screen and I can still move the mouse.
    I just ordered a 2 TB LaCie to act as my Time Machine.
    Will it harm the Time Machine ti be ejected every time I need to restart (or go to Windows)?
    I wonder what the best solution will be.
    Thanks for any help.

    This is an extra step, but try this anyway and give us the results.

    1. Choose "log out" instead of shut down.
    2. Let the account be logged out
    3. NOW choose "shut down" from the buttons at the bottom.

    Does this change the behavior?

    Thank You for your reply!!
    That worked for Restart and Shutdown, any idea why this is happening?
    Just on a side note: I eject the external then turn it off before I go to Windows through Boot Camp and there is no issue.

    I would say this is the cause:
    iTunes or some other process is locking the drive and is basically ignoring the shutdown command and/or a bug is hanging the computer. what happens if you boot the computer up w/o that external drive and then after you log in, can you plug it in and then try rebooting? Also do that as well but the next time start up iTunes and then try rebooting. What I'm suggesting is trying to narrow down the cause :)

    Good luck
