Instructions for installing SignStream® 3.3

Before launching the SignStream® application from the SignStream® folder:

1) You will need to allow the launch of the SignStream® 3 application, despite the fact that it is not provided by Apple or certified developers (to get around security features that have been implemented in Mac Operating Systems since OS 8).

2) You will also be offered the opportunity to download the latest ASLLRP Sign Bank, which consists of a repertoire of signs, with gloss labels and annotations of other properties, as well as images and video illustration of those signs, to assist in the process of annotating new video files. This Global Sign Bank is not required for use of SignStream®. If you wish to download the Sign Bank, you must first agree to the terms of use (which will also be downloaded to your SignStream® folder).

Open a Finder window, and double-click on the SignStream folder (the folder you downloaded, which includes the application and related files) to open it.

Do the following, in the order listed:

1) [Required] You will see a file called “DisableQuarantine.command”.
Double-click on that.

  • You may get a message asking if you want to open the file even though it is from an unidentified developer. If so, say YES.

  • If you get a message that the file cannot be opened because it is from an unidentified developer:

    a. Go into System Preferences > Security & Privacy > General

    b. Under the section "Allow apps downloaded from" click "Open Anyway" for this file.

This will open in the Terminal application and run immediately, then close itself when finished.

2) [Optional] If you wish to download the ASLLRP Global Sign Bank, double-click on "GetSignBank.command". You will be asked whether you wish to download the Sign Bank and agree to abide by the terms of use. If you click ‘yes’, the download of the ASLLRP Sign Bank materials (and of the Sign Bank terms of use) will commence. Close the Terminal window.

You will then be ready to launch SignStream® by double-clicking on the application.

Do not move the SignStream application out of its enclosing folder.
