I got a 2015 MacBook Pro from eBay. I’m trying to install Sierra from scratch (after completely formatting the SSD) but I get this strange extra step (although the install USB is vanilla and done using Apple’s own bootable usb tool) that I can’t pass (pressing continue asks me to connect to a IBM private network, which I obviously can’t do)

Does anyone have any info about this. Where is this MacBook comming from? How can I disable this remote management step? Is this a custom firmwere, or where does this come from?

    This laptop may be stolen property. To protect yourself, contact your local police station, constabulary, etc, as well as eBay, and report the serial number. – IconDaemon Jan 3 '18 at 18:26

    @IconDaemon I'm starting to worry that's the case. What other legit reason could there be for a 2 and a half years old enrolment Macbook sold privately outside the company? I'll contact Apple Customer Support tomorrow to see if it was flagged. Also thinking of writing IBM as well, maybe they have a database of stolen hardware ids. What can I say, I just hope I won't lose both the laptop and the cash :( – Valentin Radu Jan 3 '18 at 19:20

    Please come back after your dealings are done, we all are interested in the result! – Kyslik Jan 3 '18 at 21:51
  • @Kyslik So far so good, I've contacted Apple and it doesn't figure as stolen also contacted local police and again it's clear. Unfortunately, this doesn't make me feel at ease. Apple doesn't really have a flagged(stolen) devices register so if you turn off Find my Mac you're out of luck. As for police, really, this could have been stolen in another country or even another continent. Will contact IBM later on today, but I expect it will take a while to dig through their corporate layers. Also, big red flag is that the seller told me he got it form a friend, so, no proof of purchase :( – Valentin Radu Jan 4 '18 at 8:02

    Any update? Facing the same problem here and can't get the "owning" company to even talk to me about it. – Jeff Evans Aug 3 '18 at 20:26

This Mac has been enrolled under Device Enrollment. Upon connecting to Apple, the device has received instructions to be managed by IBM.

This cannot be bypassed. You should contact the seller.

Mobile Device Management ‘locks’ enforced by Device Enrollment are enforced by Apple’s severs and are based on hardware identification, so cannot be removed by macOS reinstallation ― they’re defined to be enforced as soon as the Mac is unboxed for the very first time prior to any manual configuration.

    What would happen if the mac was offline during the first setup process? – Alexander - Reinstate Monica Jan 4 '18 at 1:42
  • @Alexander with no internet access during the installer, it might proceed but phone home at the first chance, or it might not allow the installer to complete at all. – Criggie Jan 4 '18 at 1:46

    Ok, did some research. The way things are now, you can install the OS if you're not connected to the internet and will not be bother again later (even if you'd like to). It seems it's a flaw in Apple's system many enterprises are complaining about. This could be fixed in the future. Also, if the purchase is ligit (confirmed by initial owner), Apple can help with removing the Mac from the enrolment program. – Valentin Radu Jan 4 '18 at 8:11
