Where can I set it to full wallet? saw this just when I downloaded and started it first, don't find a part to change this on an existing one?
Close Byteball, rename your datadir (see code above) to byteball.old, and restart Byteball. It should ask you again.
Strange is, that following directory does not exist not he older library which I saved:
macOS:
~/Library/Application Support/byteball
Was it different before the current updates?
