Across shows the error, when i push the "Pair" button: Pairing failed due to error Pairing process failed due to an error (code: 7). Across pro v2.00.beta3 (2.00.2) macOS Mojave 10.14 (18A391) MacBook Pro (Retina, 13-inch, Early 2015)
Mine kinda works. I can move my mouse to Mojave, I just cannot move it back. I have to use the keyboard shortcut.
There is a solution https://community.acrosscenter.com/index.php?threads/macos-10-14-mojave-accessibility-issue.164/
