DON'T DO IT!
I have tried
@dosdude1 APFS patcher on my Mac mini 2009 and it bricked my maca mini, had to order an EFI chip, and had to go to a local eletronic shop for them to weld it on the board.
It's working fine again but I don't recomend you using it because these mac mini's were launched with several EFI chips and tho I took my mac mini apart to pick the correct one as he warned you that you should check it first, it still didn't work.
Im not complaining or anything, I knew what I was getting into, I'm a huge supporter of his work!
My advise for you is to wait it out, I know it's hard and you want to try it out, but just wait for
@dosdude1 to release his patcher with APFS patcher for machines without native APFS, his has done this already in previous patcher's, so Im sure he will release this soon.
Just wait a little longer, that's what I advise
