macOS 10.14 Mojave added a new security mechanism to prevent an app from controlling another app without the user 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. Remove the previous installed Across: From Finder, go to /Applications/Across/ and then run "Across Uninstaller". You don't have to remove the previous settings. 2. Download the below linked installer file and then install it. Pro (v2.beta): https://d2fa0wrz2qwv08.cloudfront.net/AcrossInstaller_2_BETA3-2.zip Basic (v1.40): https://d2fa0wrz2qwv08.cloudfront.net/AcrossInstaller_1_40-2.zip 3. Register acrossd in the exception list: Open "System Preferences" and go to "Security&Privacy" and "Privacy" tab. In the "Privacy Tab", choose "Accessibility" from the left-pane. Click on the lock icon on the bottom left corner and enter password. 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. PS: If you had added Terminal.app by referring to our previous workaround (https://community.acrosscenter.com/...0-14-mojave-accessibility-issue.164/#post-842), you can remove Terminal.app from the Accessibility exception list.
