Edit the settings file
- In Finder, choose Go → Go to Folder, type
~/Library/Application Support/JimiOS Alpha, and press Return. - If there’s no
config.json, create one with TextEdit: Format → Make Plain Text, then save it asconfig.jsonin that folder. - Add your settings between one pair of braces, separated by commas, for example:
{"direction_keys": "hjkl", "hide_dock": true}
- Quit JimiOS from its menu and open it again. JimiOS reads the file only when it starts.
