macOS Catalina - Unable to load onto Nano any more

Development Tools Uploading

I'm pretty sure all these boards are fine, as they were working before I upgraded. I think one actually has the blink app on it already, as the light is blinking every second. However, since upgrading to Catalina I can't upload any more. I've read around, but am not finding anything interesting yet, so I figured I would ask here if anyone knows about this.

avrdude: ser_open(): can't open device "/dev/cu.usbserial-A904OGHO": Resource busy

The port is getting created no problem when I plug in the device.

Any thoughts?

I'm just stupid.

I tried updating via Atom / PlatformIO, and it failed at first, but from the error I got, I searched and found another thread here, that said try the old bootloader, so I did, and it worked :frowning: I could have sworn I'd already tried that, but I guess not :frowning: Also, it would appear it's using 57600 now instead of 115200. In any case, back in business.
