Has anyone been seeing this wake from sleep issue in 10.13.4 ? I looked for other threads about this. Sorry if something else was already posted.
It only happens if the machine is FileVaulted and it goes into full hibernation. Upon waking up the machine will freeze. Basic sleep works fine.
Here is a posting with a pretty good description of the issue.
For now we are just looking at disabling hibernation via pmset commands and hoping that it gets fixed in 10.13.5.
