During install of 10.9.5, iMac stalled half way thru 'Completing installation' phase. Have spinning beach ball, but no progress after 1 hour. How should I proceed?
i Have a Carbon Copy Cloner backup on external drive.
Try shutting down using the power switch and then start up again.
I Was under the impression that if an OS install was interrupted, bad things would happen.
Most of the time bad things can happen, but there have been a lot of posts here about a hang, like you are experiencing, and when restarted, the installation either resumes, or it turns out it was actually done. Since you have a backup, you can fix an oops.
I found this: 10.9.5 update stalls, I reboot, and I am still at 10.9.4.
And the Bash fix cannot be installed.

Try running the combo update.
The BASH fix requires 10.9.5.
10.9.5 update stalled at 'Completing Installation' in iMac with current software. How to resume or restart?
