Hi,
Several of my clients have had problems with Time Machine after the update. It goes approximately 85-95 % then fails with error messages?
I found this resolution, and it appears to resolve it:
Yes - the problem is very much related to Time Machine losing permissions to certain files when the machine sleeps. I've worked around this (until it's fixed) by making the following changes to power management:
sudo pmset -b hibernatemode 0
sudo pmset -b standby 0
sudo pmset -b disksleep 1
What this does is prevent the machine from fully hibernating. This will affect battery life a little if it's a laptop you regularly take about the place, but in general terms this is how MacOS -used- to operate.
If you aren¡¯t experiencing the issue of Time Machine failing, feel free to ignore, but if you are, these Terminal commands have resolved it for three of my clients.
Hope it helps.
Paul
