Q: TM stuck on Preparing Backup after update to Sierra

My MacBook Pro (Retina, 15-inch, Mid 2015) is unable to get past "Preparing Backup..." stage after updating to MacOS Sierra after 3 days. Other posts on this issue point the finger to Sophos. I disabled the software, and the system is still unable to get past the "preparation" stage. 

 

I was able to backup to a USB drive -- although it took much longer than usual (I have both methods for backup).

 

I then removed the network location from the TM preferences and tried to reinstate it again. However, the system fails the last stage of adding the network drive in the preferences. So, I am only left with the ability to backup to a physically connected drive only. This is very bad and I am disappointed that Apple does not have a KB case already open on this.

 

Issues after update to MacOS Sierra:

 

1. TM fails backing up to existing network backups (irrespective of Sophos or not),

2. TM fails to create a new network location backup,

3. TM only works with a locally connected backup physical disk.

 

It has been several days after release of MacOS Sierra: I am waiting for Apple to even acknowledge a situation that is damaging to users.

MacBook Pro, OS X Yosemite (10.10.1)
