Done! 🎉

Open a Terminal (Applications -> Utilities -> Terminal)
Copy/paste the following commands into your terminal and execute them to (a) download the latest ARC Commander release, (b) change permissions to make the ARC Commander executable and (c) move the ARC Commander program to a location from where it is executable via the terminal:

First, you need to verify if your machine is using an AMD / x86 processor or ARM processor.
Terminal window
```
uname -m
```
This command will return the processor type. If it returns x86_64 , your system is x86. If it returns arm64 , armv7l , or similar, it is ARM.

For AMD / x86 processors
Terminal window
```
curl -LO https://github.com/nfdi4plants/ARCCommander/releases/download/v1.0.0/arc_osx-x64
chmod a+x ./arc_osx-x64
mv ./arc_osx-x64 /usr/local/bin/arc
```
For ARM processors
Terminal window
```
curl -LO https://github.com/nfdi4plants/ARCCommander/releases/download/v1.0.0/arc_osx-arm64
chmod a+x ./arc_osx-arm64
mv ./arc_osx-arm64 /usr/local/bin/arc
```
By moving the ARC commander binary to /usr/local/bin/ it also becomes available to other users on your machine.
Run ARC Commander from the terminal by executing:
Terminal window
```
arc
```
MacOS security note: On first execution, MacOS will not allow arc to be run. Instead it opens a pop-up:
```
> "arc" cannot be opened because it is from an unidentified developer
```
Open the Security Panel in system Preferences (Applications -> System Preferences -> “Security & Privacy”) or by executing the following command in your terminal:
Terminal window
```
open "x-apple.systempreferences:com.apple.preference.security"
```
In the “General” tab click the bottom-right button “Allow Anyway” right next to
```
> arc was blocked from use because it is not from an identified developer.
```
Head back to the terminal and execute arc again. Another pop-up will ask you to confirm by clicking “Open”.
Check that arc is properly installed by executing
Terminal window
```
arc --version
```
You should see the following or similar message:
```
> Start processing parameterless command.
> Start Arc Version
> v1.0.0
> Done processing command.
```
A global config file will be created the first time you use the ARC Commander at ~/.config/DataPLANT/ArcCommander/ArcCommander.config

Download the latest ARC Commander release

wget https://github.com/nfdi4plants/ARCCommander/releases/download/v1.0.0/arc_linux-x64

Make it executable
Terminal window
```
chmod u+x arc_linux-x64
```

Move to suitable place (e.g. in your home directory or to /home/bin/ to make it accessible for all users)

if ! [ -d "$HOME/bin" ]; then mkdir "$HOME/bin"; fi # If it does not exist, create a folder `bin` in your home directory.
mv arc_linux-x64 $HOME/bin/arc # move executable to that folder

You might have to start a fresh terminal or source ~/.profile
Test that ARC Commander is properly installed
Terminal window
```
arc --version
```
You should see the following or similar message:
```
> Start processing parameterless command.
> Start Arc Version
> v1.0.0
> Done processing command.
```
A global config file will be created the first time you use the ARC Commander at ~/.config/DataPLANT/ArcCommander/ArcCommander.config
