You can type Ainu using the Ainu input source.
On your Mac, choose Apple menu > System Settings, then click Keyboard in the sidebar. (You may need to scroll down.)
Go to Text Input on the right, then click Edit.
Click the Add button , select Ainu (scroll down in the sidebar on the left or use the search field), then click Add.
On your Mac, do any of the following to switch to the Ainu input source:
Use the Input menu: Click the Input menu in the menu bar, then choose the Ainu input source. If the input source is dimmed, the current app doesn’t support it.
You can also press Control-Option-Space bar to select the next input source in the Input menu, or Control-Space bar to select the previous input source. Or, to view all your input sources (displayed close to where you’re typing as characters or letters that represent each source), hold the Control key and press the Space bar. Continue pressing the Space bar until the input source you want to switch to is selected.
Use the Caps Lock key: You can set an option in Input Sources settings to change between Latin and non-Latin input sources by using the Caps Lock key. Choose Apple menu > System Settings, then click Keyboard in the sidebar (you may need to scroll down). Go to Text Input on the right, click Edit, then turn on “Use the Caps Lock key to switch to and from [last used Latin input source].”
Press the Caps Lock key to switch between a non-Latin input source (such as Ainu) and a Latin input source (such as English).
Use the Fn key or key (if available on the keyboard): You can set an option in Keyboard settings to change input sources by using the Fn key or key. Choose Apple menu > System Settings, click Keyboard in the sidebar (you may need to scroll down), then set “Press Fn key to” or “Press key to” to Change Input Source.
Press the Fn key or key to switch to the next input source and show all your input sources close to where you’re typing. Continue pressing the key until the input source you want to switch to is selected.
