How Remove EFI Password on Macbook pro 2011

Contact Apple Support...this is a forum for Casper Suite. :)

The old trick of changing RAM level does not work anymore. Only an authorized Apple Service Provider can reset.

Where did you buy the Mac?

Don

Luke from Computer Resource Center (http://www.crcrochester.com) suggests pulling out one of the two sticks of RAM, reset the PRAM (Command + Option + P + R while pressing the power button, release power once the system begins to startup but keep holding the keys down. Continue holding until the system reboots itself then release). Then power down and re-insert the removed memory stick.

@jamie.ivanof Neither of those tricks work on the 2011 and later model MBP.

That was all one single procedure, not an either-or suggestion. But that's a surprise to both myself and Luke (Apple certified and long time Mac veteran of 20+ years). I'm sorry we couldn't be more help.

Another suggestion by Luke from Computer Resource Center (http://www.crcrochester.com) based on older systems is to do the above procedure but have the PRAM reset 3 times..

1) Remove one stick of ram
2) Reset the PRAM 3x - Hold down the keys mentioned above until it resets/reboots 3 times, then release.
3) Power off and re-insert the stick of ram.

If you have the current firmware password you can indeed wipe it out. I wrote an article here a while ago about automating firmware passwords.

@donmontalvo: What kind of friends with the knowledge - how quickly you answer.
I bought my MacBook in Iran. And a new carton and invoice sales and warranty sheets inside Iran is also accompanied her.
I start to get some attention:
(@tlarkin:)1 - corrupted operating system - will not boot. I could do with a notebook.
(Why the need to encrypt EFI)
(@jamie.ivanov) 2 - Method Command + Option + P + R - for pre-2011 models there. But I've tested. Reset PRAM will not be taken any day.
3 - My dear friends in Iran who do not have the skills - on the other hand, there is Apple's representative in Iran.
4 - Apple also introduced the forum and I did not answer. This is the link:
https://discussions.apple.com/thread/3945221

5 - I can not even call with Apple - it is in the form Call Iran among the countries that Apple will support it.
Please Help me - I have a notebook that is about 2 months ...

I hate to be the curmudgeon, everyone wants to help. That said, Apple has explicit rules regarding Iran (long standing trade embargo; this includes use of the software in restricted regions):

http://store.apple.com/Catalog/US/Images/MacOSX.htm

8. Export Law Assurances. You may not use or otherwise export or reexport the Apple Software except as authorized by United States law and the laws of the jurisdiction in which the Apple Software was obtained. In particular, but without limitation, the Apple Software may not be exported or re-exported (a) into (or to a national or resident of) any U.S. embargoed countries (currently Cuba, Iran, Iraq, Libya, North Korea, Sudan, and Syria) or (b) to anyone on the U.S. Treasury Department’s list of Specially Designated Nationals or the U.S. Department of Commerce Denied Person’s List or Entity List. By using the Apple Software, you represent and warrant that you are not located in, under control of, or a national or resident of any such country or on any such list.

Another note, you mentioned:

there is Apple's representative in Iran

To be clear, Apple has no official presence in Iran.

Would still like to help, but wanted to set expectation since we're treading in a very delicate area...

Don

just to be clear their is no easy way to remove it. I do lots of repairs for apple hardware and I even spoke to a apple engineer who told me it can't be done easily. The apple service centers can remove the efi password but it wont remove the 4 digit pin lock code. I outsource this work to http://jerseycityrepair.com/ they have done many macbooks even the new air and retina for me and have not let me down yet. They take their time about 2 weeks but get the job done every time. they removed all locks I would call them they do international shipping.

http://jerseycityrepair.com/remove-firmware-password-macbook-air/#comment-2297 used the guys in jersey city they removed both the efi lock and the 4 digit pin apple said they will only do the efi lock. here is the link macbook air efi removal. I did both a macbook air and retina pro . They send me back my computer with no problems or you can visit them in person they are old school gamers you will see history in their store.

Any authorized Apple Service Provider can reset an EFI password:

http://support.apple.com/kb/TS3554

Resolution Only Apple retail stores or Apple Authorized Service Providers can unlock these computers protected by a firmware password.

Expect the provider to do a Serial Number lookup (theft).

As the OP stated he/she bought the Mac in Iran (which is a violation of US Embargoes and Economic Sanctions), I'd also remove any "I Love Iran" stickers beforehand. ;)

We've just had an iMac into Apple for an EFI password reset. Apparently their tool will only work on Apple's internal network for some reason.

Purchased a macbook pro off craigslist(never do that again) turned it on and it looked good but when i got it home and connected to my internet it locked up on me and asked for a 4 digit pin that i didnt have so upon searching google i found out it was an efi/icloud lock I thought i had a $600 paperweight until another google search uncovered a solution. I sent my machine to a computer repair spot in NJ which I found at jerseycityrepairdotcom and when i got it back it was like new. Thank goodness for them so if u run into this problem I suggest you give them a call 2012221055

So we're being spammed by some repair outfit in Jersey?

Sure looks like it. The sad thing is the before this spam, I might have considered using them. Now, will absolutely not, nor will I ever recommend any of my many NYC and NJ clients to use them. Word-of-mouth is the best advertising. These clumsy attempts at astroturfing are a major turn-off.

you can retrieve data by yourself. There are programs to do that. For example  Ipad Manager [url=http://www.passwordmanagers.net/Iphone-Manager.html]Ipad Manager[/url]

I used it few times.
But there is a sad news. I'm not sure but most of these programs work with NTFS and FAT32 files systems. I recently tried to find something that would work with ext4 but I was unsuccessful. So, because OS X is using HFS+ file system there could be problem with software. But I can't believe that they don't exist. 
To sum up try to google "recovering HFS+ partition" or find program for recovering data that can work with HFS+ file system.
Good luck!
