Gagal Instal Safe Exam Browser
Edel Dieringer
The following manual explains how to configure and use SEB for macOS from the perspective of exam administrators. SEB is a very flexible and modular tool, therefore documentation for examinees on how to use SEB with individual exam setups and the various exam systems it works with should be provided by the institution using SEB or their e-assessment provider.
To prevent switching to other applications or interrupting an exam, SEB disables the macOS Dock, the process switcher (Cmd-Tab/Cmd-Shift-Tab), the Apple Menu and various other items in the menu bar, the Force Quit window (Cmd-Option-Esc), normal reboot (Ctrl-Cmd-Eject), normal shutdown (Ctrl-Option-Cmd-Eject), hiding the application, printing, Expos, the Notification Center, screen shots, screen recording, spelling and grammar checking, automatic spelling correction, custom Touch Bar items and typing suggestions. In addition, various third-party applications for communication, screen sharing/remote access and screen recording are blocked. Customized settings for blocking prohibited applications are also possible.
Its possible to configure SEB to quit after the exam is submitted without having to enter a quit password by specifying a quit link and placing this on the summary page displayed by the LMS after submitting the exam.
In the browser window there is no right mouse (or Ctrl-) click popup window available, links requesting to be opened in a separate window can be set to be blocked generally, to open in the same browser window or in a new SEB window. Besides that, the browser is supporting Java, Quicktime and Flash content (as long as the required plugins are installed on the system). SEB can also be configured to always use the more secure internal PDF viewer instead of the Acrobat Reader plug-in.
SEB features an optional dock/task bar displaying an icon for the SEB browser with controls for its open browser windows and widgets. Buttons in the dock for quitting SEB, restarting exam, reloading page and a display for the current time improve usability in exams. Clicking the SEB icon in the dock and holding the left mouse button down or a secondary (right mouse button) click displays a popup menu with all open browser windows, the main browser window is at the bottom. With this menu you can switch between open browser windows.
SEB for macOS is based on the WebKit browser engine, which is also used by Safari, Apple Mail and many open source browsers (in contrast to the Mozilla Firefox/Gecko or the Chromium/Blink engine used by SEB for Windows). There might be some small differences regarding rendering of web pages in those different browser engines, so you should check all functionality of your quiz in SEB for macOS before using it in exams.
SEB for macOS can be used together with additional (third party) applications during an exam. You can download and open files linked in your online exam, edit it in a third party application and then upload the results to your online quiz/LMS again. This is only possible when SEB is used in a separate user account managed by macOS parental controls.
Please understand that you also have to configure your exam system correctly to be locked down securely. SEB is generally locking down exam client computers only, not the exam system or the quiz module of a learning management system. Check documentation for your exam/learning management system on how to lock it down correctly.
Since Moodle 3.9, there is very comfortable support for Safe Exam Browser directly available in Moodle's quiz settings. The new "deeper integration" is also available as plugin for Moodle 3.7 and 3.8. If possible, use this new SEB support in Moodle. Refer to the official Moodle documentation for details. Please note that our SEB support cannot answer specific Moodle questions, use the documentation on moodle.org and the Moodle community forums.
Sometimes hiding course navigation, link to the user's Moodle profile, logout etc. doesn't work as expected because some custom Moodle themes don't support the secure browser mode of Moodle correctly, they display links with which students can get out of the quiz during an exam. If this happens only with your customized theme and not the standard Moodle theme, then your theme is not implemented correctly. In that case you should fix the problem in your custom Moodle theme. You may also create URL filter rules which only allow to access the exam and no other parts of Moodle, but this is not trivial and we cannot provide you with any support on that.
An assessment mode has been added to the OpenOlat standard with the 10.2 release. The assessment mode allows course authors to limit the functionality and access of OpenOlat courses for exam settings. An exam setting is not limited to online tests however, IMS QTI 2.1 assessments, SCORM modules, external LTI 1.1 or 1.3 tools and all other OpenOlat course elements can be configured for such an exam setting.
One of the many security features is the enforced usage of Safe Exam Browser. An exam setting can be configured with multiple Browser Exam Key keys. As of version 16.2, OpenOlat alternatively supports configuring SEB natively within OpenOlat using the Config Key mechanism, which greatly simplifies the SEB configuration and usage both for administrators and users.
When launching a protected assessment, users are directly prompted with the config file and SEB download if not already installed. The quit-link feature is also fully integrated in the user experience enabled by a single click by the author. When using the lecture and absence management module, teachers can convert regular lectures into SEB protected assessments with a single click.
No additional software needs to be installed in order to use the assessment mode together with Safe Exam Browser. The module is fully integrated ready to use in every OpenOlat installation. The assessment mode is globally enabled / disabled in Administration -> Modules -> Assessment mode. Within the courses the configuration is done in the course menu.
You can download the DMG disk image file here. If it doesn't get mounted, just double click on the downloaded file. Then drag the SEB application to the Applications folder (you can drop it on the alias icon in the mounted volume). Make sure you don't have another SEB version 2.x on your Mac (as a .seb config file or a seb:// link might get opened with the wrong version).
When you start SEB, all currently running applications are hidden and all attached screens are covered with a black background. On the main screen SEB opens its web browser window filling the whole screen (the window can be resized and moved nevertheless). Optionally you can use a full screen presentation or customize the relative or absolute width, height and horizontal positioning of the SEB main browser window and separately for secondary browser windows.
SEB opens the webpage at the preset Start URL, which might take some seconds. Initially, as long as you don't set another Start URL (see Configuration), SEB for macOS opens the project web site displaying this documentation.
SEB can display navigation buttons in the browser window toolbar (if enabled), and if browsing back/forward has been enabled, you can use Cmd-Cursor Left to go back in the browser history and Cmd-Cursor Right to go forward in history. Cmd-R reloads the current page.
To quit SEB (while it's using the default settings), just press the quit button in the SEB dock, Cmd-Q or the red close button in the browser window. Quitting SEB can (and should in most cases) be password protected in its settings. When SEB quits, the applications which were visible before starting SEB will get unhidden again.
The Preferences window can also be opened by holding the Option/Alt key when starting SEB (also when dropping a SEB configuration file onto the SEB icon). Then only the Preferences window is opened and SEB doesn't lock the system, so you can easily edit configuration files.
After setting a SEB administrator password, users have to enter this to display the preferences window. SEB for macOS can also be configured not to display the preferences window at all, this could make sense on exam client computers.
While the preferences window is displayed, switching to other running (initially hidden) applications is possible and the screen background isn't blacked out. Also the menu bar is displayed, so SEB menu commands can be used. You can also drag and drop .seb configuration files onto the preferences window or the SEB icon in the macOS dock (not the SEB dock). In the preferences window 9 tabs with grouped settings are available.
When closing the Preferences window, SEB asks if edited settings should be saved (if you were editing a .seb settings file, local client settings are autosaved as described above). SEB also asks if those edited settings should be applied. If you answer Don't Apply, then edited settings are discarded and SEB continues using settings which were in place before opening the Preferences window. If you answer Apply, then SEB reconfigures and restarts itself using those edited settings, and the web page at Start URL is loaded.
If you apply an opened/edited .seb settings file, then SEB is running in the exam mode, same as if SEB is started opening a .seb config file for starting an exam or if the user loaded a .seb config file for starting an exam from an exam portal page. More information about this you can find in the how to use SEB 2.0 document explaining the concept behind SEB 2.x.
Detail description of all parameters in the preferences window panes follows below. You can also use tool tips (move the mouse pointer over a button, text field or other control in the Preferences window) to get a short explanation for the function of the according setting option.
You can also exit SEB while applying changed settings using the item Apply and Restart SEB in the Settings menu (menu bar or the context menu in the Preferences window title bar clicking the triangle symbol).
