Photos won't force quit, Mac won't shut down.

If you continue to experience this try the following;

1 - Boot into Safe Mode, Mac OS X: Starting up in Safe Mode, and try Photos from there. If the problem goes away reboot normally and try again.

2 - As a test launch Photos with the Option key held down and create a new, test library. Import some photos and test to see if the same problem persists. Does it?

3 - lastly try repairing the library according to the instructions in this Apple document: Repair Your Library.

Warning: If you use iCloud Photo Library with Photos, this action will cause Photos to upload all your pictures again (from Fix missing or incorrect thumbnails in Photos - Apple Support).

I tried force quit.

Trying force quit again yielded the same results.

Now, my mac won't shut down because it can't close the program.

You can force a shutdown of the Mac by holding the power button for an extended period.

Restart as normal.

Apple menu ==> force quit

or select in the activity monitor and force quit

I was going to try that but was worried it would somehow mess with the laptop. So force shutdown is a safe option?

Quit all other apps, that can be quit before doing the force shot down.

If you hold down the power button to frce a shut down some apps may be left in an inconsistent state, because they may not be able to close the documents and files properly. You will minimise the risk by first closing all apps that can be closed.

To force a single application to quit, you can send signals from the Terminal.

• Launch the Terminal.app from the Applications folder.
• Enter the text below and hit return:

killall Photos

That is essentially the same command as Force Quit.

If that does not help, try this modification:

killall Photos -KILL

The "kill" command sends a signal to the process to be terminated. Without a signal name as parameter, it is the "TERM" signal, the same as "Force Quit" will send. This request can be ignored. The "KILL" signal is the ultimate killer, it is not catchable and cannot be ignored.

KILL (non-catchable, non-ignorable kill)

This is the second time this has happened to me' same thing. Photos won't quit no matter how I try to force quit. The last time I had it happen the only thing that worked was to force close the whole computer using the start up button. I tried following your advice using terminal. It did some weird things. It makes me very nervous to use terminal as Im not a techie and Im afraid I will make a ghastly mistake. I hope Apple is watching this forum. In the mean time Im just going to force quit the computer.

For persons having this problem, I tried all possible force quitting approaches but none worked. Same as others, restarting the computer didn't work as the application was still "running".

As I do not like to force "powering off" my computer, I was trying to find a "gentle" way to do it.

At the end, my solution was to restart my mac from the Terminal by typing:

1) sudo shutdown -r now

sudo: because shutdown needs root privilege

-r: means I want to restart

now: means now

2) type your admin password

And that's it

Good luck

P.

Just click on your username on the right top menu bar, and then click "Login Window..." and login with your "root" user, fill in your root password, and you can shutdown your mac.

Hope helps!

Brilliant re killall Photos - helped me resolve this; thank you 🙂
