I have never really found a good TFTP for macOS. Is it funny that macOS is much used by network people but there isn’t a decent TFTP server?
Well, there is. macOS has it built-in, no GUI though. But that’s also fine, as long as you know to use it. It’s disabled by default, but you can start and stop it with the following commands.

### Start TFTP sudo launchctl load -F /System/Library/LaunchDaemons/tftp.plist ### Stop TFTP sudo launchctl unload -F /System/Library/LaunchDaemons/tftp.plist ### Check if its running (no process means it not running) netstat -atp UDP | grep tftp |
The TFTP daemon uses the /private/tftpboot folder so we are going to copy the file there. Then set the correct permissions on the file.

### Copy file to tftp folder cp FILENAME /private/tftpboot ### Set permissions for the folder and files within chmod -R 766 /private/tftpboot |
There is a gotcha with the TFTP daemon, which is you cant copy a file to the TFTP daemon if that file does not already exist there. To work around it you can just create a file and set the permission for it. Then your devices will just send data into the pre-created file.

### Create the file touch /private/tftpboot/FILENAME ### Set permissions chmod -R 766 /private/tftpboot |
