I have ended up with a firmware locked imac(unaware when bought) I hvae the serial number If anybody is worried if it might be stolen,I have learning disabilities which makes matters more difficult with my endeavours.

Im attempting firmware brute force with this script from here: https://forums.hak5.org/index.php?/topic/30055-payload-optimized-android-pin-cracking-script/

DELAY 150000
STRING 1234
DELAY 100
ENTER
DELAY 14000
STRING 0000
DELAY 100
ENTER
DELAY 14000
STRING 1111
DELAY 100
ENTER
ect...

after each entry the mac takes a while to actually enter hence the long delay between each, my issue is it enters the first pin,then only 1 digit in the next(a timing issue?) I have altered timing in a few places but to no success,ALSO If any one can help me generate the ducky script for 0000-9999 pin brute force I would be very greatful as producing the script myself is becoming to much of a challenge

Darren actually made a tutorial how to do this, just make a few minor changes and your good to go.

It's for android, but it's almost the same.
