About MacSKK
macSKK is an SKK-style Japanese input method for macOS 13.3 and later. With SKK you mark where kanji conversion starts as you type, instead of converting whole phrases.
It suits SKK users looking for a modern alternative to AquaSKK. It is written entirely in Swift and SwiftUI and uses the macOS sandbox to limit network and file access.
Highlights
- SKK input for Japanese on macOS
- Sandboxed, with restricted network and file access
- No third-party libraries
