Stuck in Recovery Mode After APFS Conversion

[Babz]

UPDATE 3:

Think I fixed the slow progress bar boot problem.

Zapping the Pram didn't work.

BUT, what appears to have fixed it was shutting down the Mini and unplugging the power cable for a minute or so. (This apparently is how you reset the SMC on the Mini).

So, cautiously optimistic..

Thanks to anyone who has hung with me this far..

I wish you the best, and thanks for sharing your experience. I just felt really helpless and had nothing constructive to offer, but if I'm not mistaken, wasn't APFS supposed to only work on SSDs?

Ha, thanks! It nice to know someone is out there at least!

This was a tough one, it took every trick in the book, but at this point, I'm pretty much back in business. I cloned the drive using SuperDuper to SSD in external USB 3 enclosure, then installed it in the Mini. Testing it out for several hours, going through my dozens of plugins, so far and all seems to be working well. Super zippy! I didn't even have to reauthorize 90% of my plugins (including DP). The only ones giving me trouble are Spitfire Audio LABS (which is set of FREE instruments) and Waves! Been on the phone w/ Waves tech support 3 times now! #@!$%^@#! Waves!

Well, if you're a glutton for punishment, now's the time to check out DP 10.1.
