Hi Guys

Purchased 3 macs (2X macbook air + 1X imac) on auction here in Sydney. So, when running (Command-R or Option-Command-R) recovery it installs a ventura macOS propriety of University of Sydney, even with user/password from them. I can cheat the system creating a Ventura USB with Ventura.

Since a bought them to resell, it is no nice to inform the buyier that he can't use the internet to recovery his machine.

Question: Is there anyway to remove that from the mac, apple site or HDD (if resides there)? Is that information comes from where (BIOS if the macs have one)?

Booting with my Ventura clone (option key) the problems goes away.

Thank you!

Cheers

If and only if I understand correctly

Has the University of Sydney done things right ?

What to do before you sell, give away, trade in, or recycle your Mac

And, have they removed the Serial Numbers of these computers from the MDM Service ( Mobile Digital Management ) Service Data Base ?

I would verify with them before moving forwards with any of your plans to selling the computer off

PS - There is no BIOS in Apple Computers

Before you ask about the importance MDM services.

Even if you were able to reinstall Ventura as a clean installation

The MDM Service can, at any time, take Control of the Computer as the Serial Number is still Registered in their Data Base

The Serial Number is a unique set of alpha numerical digits that are embedded on/ in the LogicBoard and can not be removed

Hello PRP_53

Well after an extensive number of phone calls they agreed with me that those Macs were registered in their database. They relase 2 of them but one still locked.

Last email they said:

"That one device that you sent a photo of in the PDF displaying an Asset Tag popup will need to be reset as it has progressed too far in the setup.

For more information on resetting the computer, visit Official Apple Support"

Any idea what he is talking about?

Thx mate!

Well well, we were right from the very beginning (sadly right )

" Asset Tag popup " not a clue what that is

What can say beyond what has been said, sadly.

Have the computer evaluated by the Professionals who have the Special Hardware Software and Expertise to diagnose the issue and offer possible solutions

Make an Appointment at the Apple Genius Bar

The above would require you transporting 1 or all of the computer and have them attempt to wipe the computers and reinstall macOS

That may challenge the Universities' assertion should the professionals not be able to put the machines right

The person or organization that conducted the Auction may have acquired the 3 Apple Computers by dubious means.

Knowingly or Unknowingly, they have sold you the computers in this statement does occur

Some of the oldest Scams, especially when selling Used Apple Devices in this state - Lock to someones MDM Service still registered and acquired by doubtful means.

Right now, they have their money and you have 3 semi expensive computers that are not useable.

Word form the wise.

When purchasing any used Apple Device, alway purchase Directly from Trusted Sources, like Apple.

Sorry, without actually knowing Who was the Previous Own was and all the very specific details of what MDM or similar type of Service was associated with the computer, you have 3 niece paperweights.

Welcome.

Apple computers that have been prepared for resale should always be done the proper way.

Anything less should be immediately returned for Full Refund

As for prompt rely, you are about 16 hours ahead from where I am located lol

As competent as they were on the first two computers.

Why would one expect them to be any more competent on this computers ?
