Just got keyboard and unable to flash

Help and Getting Started
1

Hey there, I’m having some unfortunate beginner’s problems with my just received keyboard. Neither Chrysalis nor the Arduino IDE are able to flash the board. The error response I’m getting is the following:

Arduino: 1.8.10 (Mac OS X), Board: "Keyboardio Model 01"

Sketch uses 25010 bytes (87%) of program storage space. Maximum is 28672 bytes.
Global variables use 1338 bytes (52%) of dynamic memory, leaving 1222 bytes for local variables. Maximum is 2560 bytes.

I’d be rather happy it someone were able to assist… I’ve already tried all sorts of combinations of when to press Prog with no luck.

Mac running Catalina 10.15.1

Edit: the keyboard works pretty normally otherwise as far as I can tell just plugged in and I’ve tried two different cables thus far.

According to this thread Flashing: SKETCH, LIBRARY, SOURCEDIR, and ROOT need to be set Catalina broke flashing on every ATMega32U4 based Arduino. So you won’t be able to program your keyboard before Apple pushes a fix for it.

If you have access to a windows or Linux machine there should be no problems flashing the keyboard.

I can confirm this. I got a new board (Loud Click) and was tearing my hair out trying to flash it, until I found these comments about Catalina. Worked fine on my High Sierra machine.

FYI, Catalina 10.15.2 which was released today fixed this issue.
