Time Machine not working with OS 10.13.3
I upgraded my Imac to OS 10.13.3 and now my Time Machine will not do a back-up in normal mode.
Time Machine starts preparing backup and stops when it starts calculating time remaining.
It will back-up in Safe Mode but not in Normal Mode.
Time Machine did work in normal mode with OS 10.13.2
How can I fix this problem.
iMac, macOS High Sierra (10.13.3)
