to get rid of AFP I tried to setup time machine over SMB according to How To Start Time Machine Backups Over SMB in macOS Sierra 10.12 and Higher. My firmware is 2.31.174
If I try to set the destination with tmutil, I get back the error 45:
sh-3.2# tmutil setdestination ‘smb://xxxx:email@example.com/TimeMachineBackup’
Disk does not support Time Machine backups. (error 45)
The backup destination could not be set.
I can mount the share just fine in Mojave.
Anyone tried this out yet and got it working?
