2. i did called apple two time they were help with nothing , so be it.
3. when see password wrong try again ,keep casually press all keyboard {expect space and power key it will let turn off then need wait another 60min } then after few min 4 blank fields will be back .i did two day few time casually press all keyboard then 4 fields show 3 times then i press right icloud lock code . thats it .

i had same issue and i tried to do Command+Alt+R but password not accepted. what can i do.

I had the same problem on my iMac after I locked my iMac with 4-digit iCloud PIN.

The solution in my case was to make "Internet Recovery" (Apple Support gave me this solution):

1. Power off your Mac

2. Power on and hold Command-Alt-R buttons

3. Mac boot with EFI PIN lock (padlock icon with bar)

4. Enter your 4-digit iCloud PIN or your Apple ID password and press Enter

5. Internet Recovery process can take about 10-15 min then Mac will boot normally.

If not, call Apple Support for help 🙂

No data lost was in my case of Internet Recovery

Hi

Was your mac in a loop as well?

I am facing now the same problem and since it will take at least 2 weeks before I get back home to get my proof of purchase, I can not see how I can get around it...

I can not see the 4 input boxes 😟

Please help!!

If you locked it with "Find My Mac" you may also be able to unlock it with find my Mac from your other device on the same Apple-ID. That can easier than fiddling with the passcode on the locked device.

The problem is I can’t find the Mac in the list of devices, I thing it been locked by hackers.

the mac is asking for PIN code which i don't have, what can i do.

Try resetting the password. This works for Lion and later:
