Finding a specific past beta build of macOS to install on my MBP

Almost a month back, I contacted Apple to seek help finding a particular past beta build of macOS. One of the people I spoke with on the phone later sent me the following very nice email as follow-up.

His main suggestion had been to use the Apple Feedback Assistant to get in touch with the team in charge of the betas, so I did just that, as below.

However, it's been almost a month with no response. I emailed back the person I spoke with as well (screenshots below), but no responses from there either.

I'm now not quite sure what I should do now, so any and all suggestions are welcome. If anyone knows of a way to get the specific build of macOS (build 18f127a), that'd be awesome too. Thank you!

MacBook Pro 13", macOS 10.13

It would surprise me if Apple made an old beta build available. Apple's take on older software is it is essentially forgotten as though it never existed. I have to admit, in the case of a beta, nobody else in the world would likely be using it except for you so why develop specifically for it?

Hiya, thanks for the reply :) 'Never existed' got a good chuckle out of me lol.

Maybe not openly available, but I would hope that the old beta build could be provided on request? I do realize it's an uncommon request.

As for why, I can't say much (or give specific details) due to company confidentiality, but basically a couple of beta testers had that build and some interesting behaviour was observed that I want to try and reproduce on my machine.

I do still have the case number, I'm just trying to figure how to proceed/whom to contact..

I think there's a whole developer support community and they may have better information on the back channels to Apple for this kind of thing.
