Funny it works on my Macbook M1 running macOS 26.5.2….
But I did notised that it only gives me the path (path to the binary) if RcloneView is actually running, if RcloneView is not running it only gives me rclone: in terminal.
Edit.
Actually I was thinking of the which command and not whereis.
From what I can see which works if RcloneView is running or not.
