I bought a 2nd hand imac a few days ago and was given the passwords to be able to factory reset it as it had no keyboard for the previous owner to.
I got home had it working and as i was about to factory reset it i have been locked out with a lock pin code? I have aked the previous owner and he has no idea on what it is and its not letting my bluetooth key board connect so i can type anyway.
any help wouldnt be much appreciated.
Thanks
Hi Doyles1901,
If your iMac is requesting a System Lock PIN code, a previous owner locked the iMac through Find My Mac. You must enter this PIN code in order to use your Mac normally again.
If you want infinite guesses at the PIN code, provided that a firmware password wasn't already set earlier, hold down the Option key as you turn on or restart your Mac. Release the key when a padlock and a password field appears. You can now take infinite guesses at the PIN code. To exit, force your Mac to power off by holding down the power button. If you guess the correct code, you will see a selection of startup disks to boot. Use the arrow keys to select your iMac's internal drive (usually named Macintosh HD) and hit Return. Use the same PIN code to unlock your Mac.
Or, you could also take your iMac to the nearest Apple Store or Apple Authorized Service Provider to get the lock removed. Bring proof of purchase with you if you have it.

maybe I can help you. Firstly, I've found bluetooth keyboards to be a little troublesome, especially at first startup. See if you can find a USB keyboard-any USB keyboard, doesn't have to be Mac-could be windows-as long as it works. hold down the power button and reboot, and press Command + R on the keyboard to get into the Recovery partition. From there, move the mouse to the top center of the screen, and go to OS X Tools. Go to Terminal, and type in "resetpassword" and press return. This should get you to the reset admin password application, and from there you should be able to get into the iMac. Hopefully the previous owner has de-authorized the iMac and the Apple ID account associated with it. If he/she has fileVault activated, that I can't help you with....so you'd have to post back later.
