High Sierra 10.13.2 move/copy files finder freeze issue

There appears to be a compatibility issue between the High Sierra 10.13.2 security update and Samba (SMB), the networking protocol. I believe this is an issue to do with Intel processors, but that is as far as my understanding goes.

As a result, moving files on an externally mounted drive on an internal network causes the finder to freeze, (with the message “preparing to copy…”) requiring a manual shutdown to get the computer going again.

We have found a work around as follows:

  1. Eject the drive/computer from the machine where the freeze is happening, using the eject icon in the finder window.
  2. Go to Finder > Go > Connect to server…
  3. Into the server address type afp://xxxx, where xxx is the internal ip address of the server where the drives are located.
  4. Follow your normal connection procedure from here.

This reconnects the drive using the AFP protocol. So far we have been able to have full control over our folders on the externally mounted drive on the internal network. At this point we’re not sure if this requires reconnecting each time you start up, but it would be advisable to turn of any auto load of the drives in the “login items” in your User Preferences.
