Can't connect to my new Arduino board

Development Tools IDE 1.x
1

Hello all,
First post and I have spent the last 2 hours trying to connect.
Mac 10.13.6
Arduino 1.8.13
SparkFun Pro Micro ATmega32U4.

When I first started Arduino, I was able to communicate with the board. I didn't have the correct board configured so there were upload errors but there was communication and some of the led's turned on/off. Once I installed the SparkFun board manager and the addons, I can no longer communicate. The board has power and the power led is on.

Under Tools > Ports, all I have listed is /dev/cu.serial-12345678
"lsof | grep usb" lists nothing
"ls -l /dev/ | grep usb" lists cu.usbserial-12345678 and tty.usbserial-12345678 but then I ran it again and I get nothing. It seems the device is no longer recognized at all when I plug it in.

Part of the problem (I think) is that I initially was running Parallels, and when a new device is plugged in, it asks which VM to connect it to. I did choose the Mac but now it no longer prompts when I plug something in. I have tried with a USB port in my hub and directly into the computer. When I plug and un plug in the Windows VM, there is no response as if nothing was plugged in. When I run just on the Mac, without parallels, again, nothing happens when I plug or unplug.

I realize this is complicated so I appreciate any help you can provide.
Thanks,
Dave

Hello. Please disregard my previous post. It seems I had "bricked" my board by trying to upload to it with the wrong configuration. I got lucky and was able to reset it using the "double-reset" method and I am good to go.
