Mac OS X v10.4, or Mac OS X v10.5 on a PowerPC Mac
Mac OS X v10.4 supports up to Java Release 5, as does a PowerPC-based Mac with Mac OS X v10.5. Java Release 6 is not available for Mac OS X v10.4 or PowerPC-based Macs.
Mac OS X v10.5 on an Intel-based Mac
Java Release 6 is available via Software Update for Intel-based Macs running Mac OS X v10.5.2 or later via the "Java for Mac OS X 10.5 Update". After installation, use Software Update again to ensure the most recent compatibility and security enhancements are installed. If no additional Java updates are offered, Java is up-to-date.
Configure Java Release 6 to be the default Java environment
- Open the Java Preferences utility, located in the Utilities folder, in the Applications folder.
- Drag Java SE 6 to the top of the list:
- Quit Java Preferences. The new preference order will be effective the next time a Java-based application or web browser applet is opened.
Mac OS X v10.6 includes Java Release 6 in both 32- and 64-bit versions, which may be ordered by preference by dragging items in the same manner.
