Adding Ukrainian Spell Check to MacOS
Apple provides a Ukrainian system localization and Ukrainian keyboards for MacOS, but so far no Ukrainian spell check. To get the necessary files to add this, go to
https://github.com/titoBouzout/Dictionaries
and download the files for Ukrainian. Put them in Home/Library/Spelling and activate Ukrainian in System Preferences > Keyboard > Text > Spelling.
To access Home/Library, you hold down the Option key while doing Go in the Finder.
You will have to specify Ukrainian in the spelling preferences, as the dictionary will not be recognized if it is set to "automatic" as far as I know.
