If the bootloader is running, you should see the led blinking. Did you remember to move the jumper on Boot0 back to 0? Boot0 and Boot1 should both be 0 to use the bootloader.

Well, somehow I got this working but I'm not entirely sure how. Could have been Python installs, could have been usb ports..
Certainly one thing I changed in my setup was going from a CH341 to FTDI USB to serial device, so that may have been it, but I got this normally works.
But also I had to press the reset just a second after I started the bootloader upload, so maybe there's a timeout that was cutting it off before(?)
Either way I am now able to see "/dev/cu.usbmodem411 (Maple Mini)" in my port list and can switch upload method over to "STMduino bootloader".

I would like to know exactly which thing I changed caused it to work so next time I get a board like this I can avoid the headache.
Thanks everyone.

Maybe you should google this site:stm32duino.com and look for usb serial not working...

The problem is new people come here .. each one hasn't read the wiki or done any research.... they start a new thread thinking they are unique in having usb / bootloader / serial issues ... they start a new thread and then we end up with another solution making it harder for the next person to find the answer.

I don't know the answer to this problem except to try and ignore these threads

A solution could be to delete threads that don't get anywhere, so people doing a search has a higher likelihood of landing in a thread with an actual solution.

This is why sometimes I revive an old thread is the new post is directly related to it, to reduce the number of short threads with little actual content or context on them

Attention: Black Pill's VBAT pin be connected to Vcc - 3.3V.
It means you can't running longtime by battery to keep the data of RTC register.
