Setting up Java on the Mac

ThomsonNOW's on-line learning environment makes use of the free Java Runtime Environment (JRE) browser plug-in for advanced features. Macs have Java installed already; depending on your browser, however, you may need a specific version for ThomsonNOW.

Most students won't need the JRE for ThomsonNOW, but it is recommended. For instructors, administrators, and ThomsonNOW authors, the JRE is required.

Testing for Java

The following problems in ThomsonNOW indicate you may need to install Java or install a different version (see System Requirements for details).

To see if you need Java

The browser freezes at the System Check or when you try to load or print an assignment.
You get an internal error when taking a test.
Graphs do not load properly.
Large gray or red boxes appear on the screen.
