No, they don't necessarily contradict each.

possession of proof of purchase does not mean ownership, at least not in my country. Alternatively you can own something without possessing proof of purchase.

They contradict what evidence he has of the transactions necessary. Given his sequence of events and statements, neither I nor you can say who owns the devices, when asked he hasn't clarified the position much, no reference to what his parents or he signed up to, no reference to how the fees were described, basically no "working" for the "solution". Being at school he should understand that gets you minimum marks.

If the school has proof of purchase then the school owned it. Unless he can show proof of purchase, even by school statement, then the school <still> owns it.

Must say for someone who completely misunderstood a poster's reference to the OP's other posts, and started to make off the cuff accusations on the basis of that misunderstanding, you really are starting to chuck rocks in a glass house...

What we're witnessing here is the creep of totalitarianism from the mainland into the schools of Hong Kong...

LOL - no I think we are witnessing a school trying to control their network to prevent rife copyright theft and network security issues - a complaint that has been levelled at China for years, the irony is that now we see that starting to be reversed, it is the Westerners criticising the school...just too funny.

At the end of the day the school doesn't have to teach him, and if he can't use the MBP in class his education may suffer (lets assume for a minute there actually IS a sensible reason why the school encourages/provides these machines at all, perhaps they are quite vital for in-class work? Perhaps the school doesn't provide computer lab for exactly the copyright/scam hosting/hacking reasons??)...but that seems unimportant to you?

If he wants educating at that school he should comply with their policies whether the machine is his or not, otherwise he should go elsewhere.

It's simple then. No EFI password = the Mac stays off the school network.

But then really, there is not much from stopping him taking any old laptop into school and using their network. I can't think of any effective way to stop this.

Network Access Control (e.g. 802.1x) will easily prevent people from attaching "any old laptop" to the network.

Can you clarify this? What specific protocol will prevent unauthorised devices and how? At what layer does it operate and what identifier is it using to filter access?

Lets stop with the bickering. The last couple of posts were removed because they were derailing the thread.
 
Need to remove FW Password! o_O

Before you reply to this thread, or even read it, please note that I am responsible for anything that happens because of this.

I've lost my Firmware Password.

Is there ANY way to reset it without removing DIMMs? This MacBook is a latest model, so I think it won't have any effect.

The system is brand new with two accounts: Administrator and Student.

Student has no password. Administrator is locked and I cannot log in to it.

This is MY PROPERTY. Please do not reply about this, it does not contribute to my problem. The computer was bought legally with my money, outright.

Perhaps if I can obtain administrator elevation, I can retrieve / reset the password from the terminal?

Many thanks,
Cryosim

Note: Please do not relate this thread to any others I may or may not have posted in the past.
 
Is it definitely a firmware password? If it's just on Filevault you should be able to boot up the machine with recovery media and wipe. Could definitely try a Linux USB or some such if all else fails.

Otherwise I'm genuinely not sure but fingers crossed someone else can help.
 
Yep, definately a FW password.

Perhaps if I can get admin on the computer, with the use of some kind of hack, I can use setregproptool to reset it?

But I don't see me getting sudo unless I reset the FW password first... any ideas?

A firmware password means you can't boot from an external device. You will be prompted for a password when you hold down Option at boot.

If that doesn't happen, it's just a FileVault password and can be bypassed by reformatting the entire drive.

I assure you, it's a firmware password.

When I CMD+R it comes up with a lock and PWD input.
 
If its a firmware password, there's no work around. You may be able to take it into apple with verification that its your laptop but I'm not sure they do that sort of stuff.

That's my Plan B. Only because I need to make an appointment. Isn't there an exploit that can be used to obtain root / sudo?

No, and I'm glad there isn't. Firmware is preboot up. Root access is OS level.
 
I didn't. But the school did (again this is my legal property, please do not question it)

Then go to your school and get someone to log into the machine. If they won't then they'll be able to explain to your face why and we'll finally be done with this thread.

I own my Phone, but to put it against my corporate Exchange server I allow them to control it. It really sounds like something similar.
 
2015-02-12 This is just another "I forgot my password" thread, so sooner closed the better, "think about it"...

Anyone surprised here ? OP has the answer; return the Notebook to Apple with the appropriate paperwork, and stop Phishing for exploits to unlock/bypass security features...

The OP has his answer, and he has his options. I find it fruitless to continue the discussion any further as it will only cause more bickering.
