2.2 Installation and Removal on OSX

2.2.1 Installation

macOS 10.13 and later: Across uses the latest version of openssl which Apple does not support any more. So, if you do not have the latest version of openssl, it must be installed beforehand. The simplest method is using brew.

Across will search for the openssl libraries (libssl.1.0.0.dylib and libcrypto.1.0.0.dylib) from /usr/local/opt/openssl/lib and the openssl binary from /usr/local/opt/openssl/bin. If you already have openssl installed using other method, please make symbolic links pointing to your version of openssl files, in the corresponding directories (/usr/local/opt/openssl/lib, /usr/local/opt/openssl/bin).

  1. Download and Launch the Across Installer: Launch the Across Installer by double-clicking the downloaded installer file.

  2. Agree and Confirm: Read carefully the Across EULA (End User License Agreement) on the installer’s License Agreement phase and if you agree to all of its terms, click ‘Agree’. When the installer requests your password, enter your password.

  3. Get Started: Upon completion, you can see that Across is running in the Dock. The Across Client mode is the initial operation mode. You can find how to switch the operation mode of Across in the next chapter.

  4. macOS 10.14 and later: macOS added a new security mechanism to prevent an app from controlling another app without the user’s consent. That is, you are able to register an app explicitly as an exception in the allowed list from ‘System Preferences’. To do this, please follow the steps below:

    1. Open ‘System Preferences’, and go to ‘Security & Privacy’ and ‘Privacy’-tab. Choose ‘Accessibility’ from the left-pane from there.
    2. Click on the lock icon on the bottom left corner and enter password.
    3. From Finder menu bar, click ‘Go’ > ‘Go to Folder…’ and then input /usr/local/sbin to the ‘Go to the folder:’-path. Click acrossd and drag-drop it to the exception list.

    Note: Even if acrossd is listed in the exception list, macOS could not apply it as an exception. In this case, please try to remove acrossd from the exception list and then add it to the list again.

  5. Autostart Control: Once Across starts to run, Across will keep autostarting whenever computer starts. However, when you exit ‘Across Center’, you will get a confirmation message box asking you whether you want to keep autostart of Across enabled.

    When you want to run Across, open ‘Across Center’ located in /Applications/Across/ and when ‘Across Center’ requests your confirmation, enter your username and password.

2.2.2 Removal

  1. Using Finder, go to /Applications/Across/ and launch ‘Across Uninstaller’.
  2. You can cleanly remove Across with all its settings by checking the ‘Remove all settings completely’ in the uninstaller. When the uninstaller requests your password, enter your password.
