Help me! my iMac 2013. Buy may 04, 2013 is locked, i need a pin code of four digits to unlock.
iMac, OS X Mavericks (10.9.2)
Have you set up a pass vide for Find My Mac in iCloud? http://support.apple.com/kb/TS4006
Pass code
Nope, my imac is not present in iCloud
It sure sounds as though you or someone else has activated find my Mac and if so the only way to get it going again is to take it to the nearest Apple Store or AASP where they can reinstall the firmware. This can only be done by Apple technicians. Good Luck.
iMac is locked, asks pin code of 4 digits
