brand new mbp tonight...decided hey I’ll do a clean install since it’s a new machine and I wanted to have a baseline that I knew I personally wiped clean etc.

Ran into the fact security utility wouldn’t let me boot from an external drive. Told me to restart into disk utility and change settings...ok fair enough....too bad I had already wiped my HD clean and it gave me an error explaining there was no administrator found. So I wasn’t even able to change the settings.

Absolute ******** someone has to go through this.

Now I’m forced to recover via internet and all it’s allowing me to download is high Sierra. So now I have to download and install that then upgrade to Mojave I guess.

****ing ridiculous **** you apple ****ing shitbags
 
Uh, how exactly did you wipe it? I believe you only need to boot to recovery and reinstall... Or make a USB installer and boot from that.

Also, this is a mac. Not a PC. Wiping it when you buy it is pointless unless it's a used mac you got from a private party. The same stuff will be on the download from apple as what came with the computer. We don't have bloatware like the proprietary PC (IE dell or HP) people do.

This may also be useful to you.

I feel like you put yourself through a completely unnecessary experience of pain by wiping a brand new machine. However, it is yours to do what you wish with!
Not being able to boot from an external drive does suck, but I think the amount of people pleased by security features the T2 brings would outweigh those who boot from external drives. Again, I don't know, just speculation.
 
Other people ran into the issue related to the increased security. ITs no longer a simple process of wiping and reinstalling. The T2 chip has been giving other folks headaches on a number of fronts.
 
https://support.apple.com/en/HT204904 - Hold Command + Option + R when you boot. It will install the latest version of macOS compatible with that Mac. Not a bad idea on a new Mac - you can be guaranteed you're running the latest build compatible and won't have updates.
Unfortunately it was only showing High Sierra Available through that Avenue. I have resolved the issue anyway.

Had to reinstall Sierra, then change security settings then boot from external.
 
and could you explain the benefit of a clean install on a new mac? since it starts out with... a cleanly-installed OS, just waiting for someone to dive into...

how is it apple's fault if you choose to over-complicate setting up your new mac?

I don't own a t2 Mac yet (probably not until next spring), but the very first thing I intend to do once one is in my hands is to DISABLE every t2-related "feature" than CAN be disabled.

And then... go on from there.

"just curious; why?"

Well, just because I want to... ;)

I prefer as little "encryption" as possible, preferably, none at all.
I WANT my drives and data to be "in the clear".

I want to be able to boot and run from external drives.

If possible, I'd like to reformat the internal drive to HFS+ and run that way (but, unfortunately, I don't this is possible with the t2 chip).
 
not possible nope.. High Sierra and above will convert to APFS, and new Macs cannot downgrade sine no chipset support for older OS's... Since you have a T2 chips it's a new Mac.

The only option is buy an older Mac laptop

Yes, Apple should be ashamed for enhancing the security of Macs everywhere.

As you found out, all you had to do was enable booting from external media *before* you decided to wipe the drive for no reason.

If you're going to go 'off the beaten track' it's probably a good idea to actually know what you're doing.
