I wrote a short script to set the firmware password on our Mac OS 10.11 machines. Here's the line in question:
/usr/sbin/firmwarepasswd -setpasswd 1Password2Goes3Here -setmode command
It appeared to work when run, but now the Mac in question will not accept anything I give it as a password. I think I used the command incorrectly and I'm not sure what was actually set as a password. Any suggestions as to what I should try, based on the line above?
Thanks in advance!
The same thing happened to me, luckily on a test unit. Seems like firmwarepasswd wants user input, rather than the password in a parameter. In my case the password was blank, as it sent a newline. I suggest you try booting the machine, running sudo firmwarepasswd -delete , authenticating and then hitting return at the firmware password prompt.
To script firmwarepasswd in a #!/bin/sh, here's what worked for me:
#!/bin/sh /usr/bin/expect -c "spawn /usr/sbin/firmwarepasswd -setpasswd ; expect ":" ; send "1234\n" ; expect ":" ; send "1234\n" ; interact"
i tried this your script, from terminal efi password was configured succesefuly, but when i sent this script by MDM ( MobileIron) it has not been set .
/usr/bin/expect -c "spawn /usr/sbin/firmwarepasswd -setpasswd ; expect ":" ; send "1234 " ; expect ":" ; send "1234 " ; interact"
