Darwin/amd64 installs wrong tools (darwin/amd64)

[umbynos]

Describe the problem

Running the getting started on MacOS with Amd64 architecture causes the agent to download the wrong tool system (when multiple macOS systems are available for a tool) an example of this is the arduino-fwuploader which is available both for amd64 and arm64.

To reproduce

Connect a board with an old fw (for example Nina 1.4.3) to the PC and add a new device in Arduino IoT Cloud. Perform the getting started. It should fail trying to run the arduino-fwuploader with an error similar to Bad CPU type in executable.

(The problem is that the agent has downloaded the arm64 binary instead of the amd64 one)

Expected behavior

The agent should download the correct binary

Arduino Create Agent version

1.2.7

Operating system

macOS

Operating system version

N/A

Browser

N/A

Browser version

N/A

Additional context

The problem should be fixed in

arduino-create-agent/tools/download.go

Lines 67 to 74 in 58d2960

	var systems = map[string]string{
	"linuxamd64": "x86_64-linux-gnu",
	"linux386": "i686-linux-gnu",
	"darwinamd64": "apple-darwin",
	"windows386": "i686-mingw32",
	"windowsamd64": "i686-mingw32",
	"linuxarm": "arm-linux-gnueabihf",
	}

Even better would be to use the Arduino CLI way of detecting and downloading a tool: https://github.com/arduino/arduino-cli/blob/08d746dd9c31ce75b94a2c3caced3e34b6687f6a/arduino/cores/tools.go#L126-L213
