TFTP on macOS

Before entering tftp, change your directory in terminal where the file you want to push is sent.

tftp 192.168.x.x

Prompt switches to tftp>

 
bin
# sets tftp to binary mode
trace on
# gives you verbose output
put [firmware file]

The server is disabled by default.

Starting the TFTP server

sudo launchctl load -F /System/Library/LaunchDaemons/tftp.plist

Stopping the TFTP server

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
