Installing the JDK from a File Archive

You don't have to modify your security preferences if you install the JDK from a .tar.gz file archive, in particular, a prebuilt OpenJDK package. However, the system may warn you the first time you run a Java command-line tool.

Running a Java Command-Line Tool for the First Time

When you run a command-line tool for the first time (such as java), depending on which app (such as Safari or Firefox) you used to download the installer, a window may appear with text similar to the following:

'jdk1.8.0_231.jdk' is an app created by Safari. Are you sure you want to open it?
