MP 1,1-5,1 Mysterious Popup on Screen

[tsialex]

I did close Disk Utility but there was no way I could find to open Terminal in Disk Utility. There was no menu selection for anything even close to it. Is there another way to open Terminal, a keyboard shortcut maybe? View attachment 2096609
I clicked on everything in the menu. It is a mystery to me. This reminds me of microshite, every time they do a minor update, they change something but don't tell anyone.

Why you are looking in Disk Utility?

It's on the main menu, is the screen that will display right after you boot Recovery, (or after you select the Language that you gonna use, if you are booting Recovery for the first time/or after a NVRAM reset):


Sierra Recovery language selection screen, usual only opens the first time you boot Recovery or after a NVRAM reset:

Sierra Recovery Main screen, click Utilities, then click Terminal:

After you opened Terminal, type csrutil disable and press Enter key:

Now you can close Terminal and then Restart.

I read the Apple Instructions and it said "Launch Terminal from the Utilities menu." So I opened Disk Utilities. Fuzzy instructions from Apple eh? As clear as mud. Well not really, the majority of the audience that read them, are Mac and Apple users, not the other lot on the other side of the fence. So bear with me.🙃🙃
I'll go through it again tomorrow or Wednesday. I'll report back then.

@trixman Regarding having any MDM profiles installed, if you go into System Preferences, do you have an icon for "Profiles" there? If you do, then you have a profile installed - go into the option and take a screenshot, please.

BTW, it's not coming from the internet. It's a Management Profile that was installed by someone or by an app, or was embedded inside the BootROM by the original owner of the Mac. It's already in your Mac, in one way or another.

How can you tell it's not coming from the internet? Just curious. I thought DEP-enrolled Macs get the same pop-up seen in the first post when the Mac periodically checks to see if its serial number is registered in an enrollment program.

There's nothing fuzzy about the instructions. You're quoting from Apple's site but interpreting it totally differently.

To disable SIP, you do it from Terminal within macOS Utilities, after booting into Recovery. This 3rd page of the thread has all you will ever need to do this.


Now, what you quoted before from Apple's site is not the access to Terminal you are after. The Utilities Folder contains quite a few Apps. Terminal is one, Disk Utility another, and there's more. An example:


Yes, normally you have access to Terminal from here. But to disable SIP you need to access Terminal from Recovery itself, as @tsialex has outlined on this page. So for now don't go into Disk Utility App at all.

MacPro5,1 can't be DEP-enrolled from the factory, it's for 2013 and later Macs. It's a MDM profile installed into macOS or it's embedded into the BootROM.

In posting #24 the OP says that he downloaded a Sierra installer from an unspecified source on the Internet. My guess is that he downloaded a dodgy installer from a place other than Apple, and it came with the MDM embedded in it.
