Warning
On macOS Sequoia Beta 4, the Git File History does not show the correct state. We are investigating whether we can provide a workaround. On non-beta macOS versions, everything works as expected.
such a shame what happened to this once great app. Ever since Black Pixel acquired the app, development was minimal. Now Black Pixel got acquired from another company, so I don't have much hope that things will improve.
