tried everything by now… not working. same odd error "The network backup disk does not support the required capabilities"
even a freshly installed Mojave macOS on another macbook gets the same error. so I assume I have to search here at unraid for the solution. did exactly what everyone else did. hidden time machine, normal, secured, public, empty directory, deleted share, created a new one
every time the same error. its mounting the drive but error 45 in console. I can upload files to it, its not about write permissions
