there
yep title sez that all.

Thanks for clicking on the tab to giva shi-lookies,
i have a MBP 2012 the good one, we all drool over now, ya' know that one with 2 ssd bays since dvd is no more.
anyways no matter what i do's, terinimal-MrMac-support and sacraficing an  gift card, pray to Feist... did not remedy this
today as Internets Recovery only wanted to install Mojave, which is on the other ssd drive.
i know peoples on our well your planet are starving, voters still voting, flight delayed, taylor spears BF drops balls, oh canada, global harming is rampant, revised movies- TV are worse than bazooka joe comics as we should remedy these first.
BUT
why can't i install a LIONese osx on a blank pure ssd?

mercy buckets for reading this tripe!
 
Just a guess but you might need to install Mountain Lion or later onto your MBP. Even though it's a 2012 model the Mac will only allow installation as far back as the OS version that it originally shipped with, not any earlier versions. Mid 2012 MBPs came with Lion installed but Late 2012's came with Mountain Lion.

Further to that, because the Late 2012 model was manufactured up until 2016 your Mac could have originally been sold with an El Capitan installation. I had an issue once with someone who purchased a Mac just before a new OS release and then had to return it and get a replacement. The replacement was on the newer OS but some software that they needed wasn't supported but there was no way to install the older OS even though the hardware was exactly the same (the technical reasons are beyond me - something to do with firmware, grumble, grumble...).

You have mentioned Internet Recovery and this will be your best way of getting the earliest possible Mac OS version onto your hard drive. There are two versions of Internet Recovery and I think you will need to use the second one:


Version 1
  • Option-Command-R: Start up from macOS Recovery over the internet. Use this key combination to reinstall macOS and upgrade to the latest version of macOS that’s compatible with your Mac.
Version 2
  • Option-Shift-Command-R: Start up from macOS Recovery over the internet. Use this key combination to reinstall the version of macOS that came with your Mac or the closest version that’s still available.

Mountain Lion always worked with this MacBook Pro 2012
I have installed that OS many times until these last Tim years.

perhaps Option-Shift-Command-R might do that trick?
34 to17 minutes in an hour…..but progress?
Nope!

OP:

Have you tried creating a bootable USB flashdrive installer?

And then, completely erasing the internal drive and try a new installation that way?

You must back up any data you want to save on the drive first, it will be erased.

There are "alternate ways" of obtaining the Mountain Lion installer if you can't get it from Apple.

There are also solutions to creating the bootable USB installer:
- DiskMaker X
or
- Install Disk Creator
Download BOTH of these tools (free). If one doesn't work for you, try the other.

The free app "Mist" will download a copy of the ML installer.
BUT... BE AWARE that Mist runs only on newer Macs and OS versions, so you can't obtain or use it on older Macs.

"Can't download the additional components needed to install Mac OS X.​


The certificates for several of Apples OS's expired in October 2019, Apple have been very poor at getting these updated on their Recovery Servers with valid certificates. This may be the problem you are experiencing.

Try this workaround, we are going to set the time and date on your mac to a date previous to the expiry date of the certificates.

Boot to your Recovery HD, click on Utilities in the menubar select Terminal.

Enter a new date, for example or just copy and paste

sudo date -u 011421002018


press Return
enter your password
press Return

Now try downloading the OS.
If this works when the OS is installed and booted up you can Open System Preferences> Date & Time
and reset the time back to today."

only seven times on 3 ssd drives and 2 thumbs drives of 3 different Mt Lion editions.
even time machine back up wont work, bu ti have a 500GB I might get a new drive for.
as that defeats the purpose of a fresh install I performed many times.

I will try those last 2 things out, FM!
thank!~>

I will try this later today.

I also feel that since I have a robust .49¢ in my iCloud, that might be a problem too?
 
OP:
Can you get ANY version of the OS installed and bootable?

It's why I made the following "#1" on the list:
Fishrrman's "Mac Rule Number 1":
A Mac that boots (to any version of the OS) is preferable to one that won't boot at all.
