They are only intended to gather more information which might provide a clue that eventually leads to a solution. NOTE: These instructions will not solve the problem. Hi I'm going to ask you to post some additional information that might help us to identify the problem. If not, install it and then try compiling again. That may no longer be the case when using the Apple Silicon build of Arduino IDE, since Rosetta 2 is not required to run the Arduino IDE application itself (only the many x86-64 tools used by Arduino IDE).Īnyway, please make sure you have Rosetta 2 installed on your computer. So users with Apple Silicon-based machines that didn't already have Rosetta 2 would likely be presented with the Rosetta 2 installation dialog as soon as they started Arduino IDE. Previously, there was only an x86-64 build of Arduino IDE. Arduino only created this Apple Silicon build of Arduino IDE 2.x last week. I asked it because I had a hypothesis (I don't have access to a Mac so I can't check) that, because it is executed by Arduino IDE as a subprocess, macOS does not present the Rosetta 2 installation dialog when running avr-g++. I didn't ask this question because I thought using the ' macOS Apple Silicon, 11: “Big Sur” or newer, 64 bits' variant of Arduino IDE might solve the problem. Many such tools are used by Arduino IDE, so even if you are using the Apple Silicon build of Arduino IDE, Rosetta 2 is still required. The avr-gcc toolchain is a completely separate component which is currently only available in x86-64 builds for macOS. The native Apple Silicon build of Arduino IDE is only the Arduino IDE application itself.

I tried reinstalling it anyway (the Apple Silicon OS), but got the same 'bad CPU type' when I tried to compile again.
